The  
I n te rna l  Ba t te r i es 
Status Indicator, which appears 
in the screen’s top left 
corner, lets you know the 
status and charge level 
of the analyzer’s 6 1.5 V batter-
ies. The X shown in the figure 
shows that the EXP is powered 
by the battery you’re testing to 
conserve the internal batteries. 
Press the two Soft Keys linked 
to the bottom of the screen to 
perform the functions displayed 
above them. The functions 
change depending on the menu 
or test process. So it may be 
helpful to think of the words 
appearing above them as part 
of the keys. Some of the more 
common soft-key functions are 
SELECT, BACK, and END.
When you first connect the EXP 
to a battery it functions as a 
voltmeter. The voltage read-
ing appears 
above the left 
soft key until you move to other 
menus or functions.
In some cases, you can use 
the Alphanumeric Keypad to 
enter numerical test parameters 
instead of scrolling to them with 
the ARROW keys.
You’ll also use the Alphanu-
meric Keys to create and edit 
customer coupons. The keypad 
includes characters for punctua-
tion. To add a space, press the 
RIGHT and LEFT ARROW keys 
simultaneously.
The Selection Area below the 
Title Bar contains items you se-
lect or into which you enter infor-
mation. The area also displays 
instructions and warnings.
The Directional Arrows on the 
display show you which Arrow 
Keys to press to move to other 
icons or screens. The Up 
and Down Directional 
Arrows, for example, let 
you know to press the 
UP and DOWN ARROW 
keys to display the screens that 
are above and below the current 
screen. 
The Left and Right Directional 
Arrows let you know to use the 
LEFT or RIGHT ARROW keys 
to highlight an icon for selection.
Another navigational aid is the 
Scroll Bar along the right side 
of the screen. The position of its 
scroll box tells you which menu 
screen you’re viewing.
The Title Bar shows you the 
name of the current menu, test 
tool, utility, or function.
Press the POWER button to 
turn the EXP on and off. The 
EXP also turns on automatically 
when you connect its test leads 
to a battery.
Whichever way you turn on the 
EXP, it always highlights the icon 
and setting you last used for 
your convenience.

Data Entry Methods
To perform a particular test or function, the EXP will ask for different types of information. This means 
that the methods you use to enter information will change depending on the type of information re-
quested. The four types of entry methods are described below. 
Typically, the soft key below the right half of the screen confirms your choice, although the word above 
it may vary. In Figure 7, for example, the word is SELECT; in Figures 8 and 9, NEXT; and in Figure 10, 
SAVE. In a similar fashion, the soft key below the left half of the screen cancels your choice or returns 
you to the previous screen, although the word above it may also vary. 
Menu icons
A menu icon is a graphical representation of a function you can select, 
such as the Diode Icon in the DMM Menu. To select an icon, use the 
LEFT or RIGHT ARROW key to highlight it. Highlighting changes the 
icon to a white picture on a black background as shown in Figure 7. To 
confirm your selection, press the appropriate soft key.
Option Buttons
Some lists have option buttons before each item. To select an item, use 
the UP/DOWN ARROW keys to move the dot into the button next to the 
item you want. You can also use the alphanumeric keypad to enter the 
number preceding the option button. To confirm your selection, press 
the appropriate soft key.
Scrolling Lists
Scrolling lists contain items that extend above and below the screen 
or the selection box that contains them. To indicate that there are 
more items, the symbols 
 appear to the right of the first visible or 
highlighted item on the list. 
To select from this type of list, use the UP/DOWN ARROW keys to 
scroll to the item, or use the keypad to enter your choice, and press 
the appropriate soft key.
Alphanumeric Entry
Some selections require you to use the alphanumeric keypad. These 
“user-defined” selections have a blinking horizontal line (cursor) to the 
right of the last character (Figure 10). 
Use the UP/DOWN ARROW keys to highlight a line for editing. Display 
the character, symbol, or number you want by rapidly pressing its key 
as many times as needed. If you pause, the cursor moves to the right. 
To backspace, press the LEFT ARROW key. Use the RIGHT ARROW 
key to add a space. Use the UP/DOWN ARROW keys to highlight a 
line for editing. When finished, press the appropriate soft key to save 
your settings.

Chapter 3: Test Preparation
Inspecting the Battery
Before starting the test visually inspect the battery for:
• Cracked, buckled, or leaking case. If you see any of these defects, replace the battery.
• Corroded, loose, or damaged cables and connections. Repair or replace them as 
needed.
• Corrosion on the battery terminals, and dirt or acid on the case top. Clean the case and 
terminals using a wire brush and a mixture of water and baking soda.
• Low electrolyte level. If the electrolyte level is too low, add distilled water to fill up to 1/2 
above the top of the plates and fully charge the battery. Do not overfill.  
• Corroded or loose battery tray and hold-down fixture. Tighten or replace as needed.
Testing Out-of-Vehicle
The preferred battery test location is in the vehicle. However, if you plan to test out of the vehicle:
• Always disconnect the negative cable from the battery first and reconnect it last. 
• Always use a carry tool or strap to lift and transport the battery.
CAUTION: When testing side-post or group 31 batteries, always test using lead terminal adapters 
provided with the EXP; do not test at the battery’s steel bolts. To avoid damage, never use a wrench 
to tighten the adapters more than 1/4 turn. Failure to properly install lead terminal adapters, or using 
adapters that are dirty or worn, may cause false test results.  
Testing In-Vehicle
The preferred test position is at the battery posts. If you must test at a remote-post location, it should 
have both a positive and negative post. Otherwise, you must remove the battery and perform an out-
of-vehicle test.
At the start of the test, make sure all vehicle accessory loads are off, the key is not in the ignition, and 
the doors are closed.
Connecting the Battery Test Cable
CAUTION: Do not connect the EXP to a voltage source greater than 30 Vdc.
Connect the battery test cable to the EXP by first aligning the cable connector’s 6 pins with the holes 
on top of the EXP. Firmly insert the connector and tighten the locking ring.
Connect the clamps to the EXP: the red clamp to the positive (+) terminal and the black clamp to the 
negative (–) terminal. 
Chapter 3: Test Preparation
• 18 •
If you connect the clamps in the wrong polarity (positive to negative or negative to positive), the EXP 
displays CLAMPS REVERSED! Reconnect the clamps.
To make sure both sides of the clamps are gripping the terminals, rock the each clamp back and forth. 
A poor connection will prevent testing, and the EXP will display the message CHECK CONNECTION. 
If the message reappears after you have correctly reconnected the clamps, clean the terminals and 
reconnect.
Connecting an Accessory Cable
If you are using an accessory cable, plug it as you would a phone jack into the accessories port on 
top of the EXP. It locks automatically into the port. To remove it after testing, press the lever and pull 
the connector out.
Setting User Preferences
Before starting your test you may want to customize the use of your analyzer by setting preferences 
in the Utility Menu. The menu has settings for the display’s date and time, the contrast and backlight 
time, a utility to customize printouts for the optional IR printer, among others. The utilities are described 
in Chapter 10.
To conserve the analyzer’s internal batteries, the EXP will turn off after 30 seconds of 
inactivity.

For the next few seconds the EXP will display the word TESTING and a stopwatch while 
it evaluates the battery. The analyzer will also display your selected rating standard and 
units or JIS part number.
Additional Test Requirements
For a more decisive result the EXP may ask for additional information or probe deeper into the 
battery’s condition. The following messages and instructions may appear before the analyzer displays 
the results of your test. 
Temperature Compensation
   
Surface Noise/Unstable Battery
The battery will hold a surface charge if the engine has been running or after the battery has been 
charged. The analyzer may prompt you to remove the surface charge before it begins testing.
1. Follow the EXP’s instructions indicating when to turn the headlights on and off.
2. The analyzer will resume testing after it detects that the surface charge is removed.
If the analyzer detects that the temperature of the battery 
may make a difference in the result, it will ask you to 
measure the battery’s temperature with the analyzer’s 
built-in temperature sensor. 
The sensor is located in the top left corner of the EXP. 
An arrow moving diagonally across the display will show 
you how to angle the EXP so that the sensor is pointed 
directly at the battery.
Press the NEXT soft key to continue.

Chapter 6: System Test
Before starting the test, inspect the alternator drive belt. A belt that is glazed or worn, or lacks the 
proper tension, will prevent the engine from achieving the rpm levels needed for the test.
The System Test includes 3 tests that provide a complete diagnosis of the vehicle’s electrical system:
• BATTERY TEST
• STARTER TEST
• ALTERNATOR TEST
The System Test includes the option of using an amp clamp.
You also have the option of viewing or printing the results at the end of each test, or at the end of the 
entire test sequence.  
Battery Test
The System Test includes a test of the battery to eliminate it as the cause of starting or charging 
problems. See Chapter 4 for the Battery Test procedure. 
If the EXP determines that the battery needs assistance to start the vehicle, it will prompt you to begin 
the Jump Start routine described in Chapter 8. 
Starter Test
If you are using the amp clamp, keep it clamped around the negative (–) battery cable.

3. REV ENGINE WITH LOADS OFF FOR 5 SECONDS: Rev the engine with the loads off. 
Gradually increase the rpm until the analyzer tells you to HOLD the rev level as the bar on 
the display crosses the rpm target line.
NOTE: Some 8-cylinder and older vehicles idle at a high level after starting, allowing the 
analyzer to detect the rev automatically.  
4. ACQUIRING DATA....HOLD ENGINE RPM: Continue to hold the rpm while the EXP takes 
system measurements.
5. ENGINE REV DETECTED, IDLE ENGINE: The EXP has detected the rev. Press the 
NEXT soft key to continue.
6. TESTING ALTERNATOR AT IDLE, LOADS OFF: The analyzer will next test the engine 
at idle for comparison to other readings, and then test the diode ripple. Excessive ripple 
usually means one or more diodes have failed in the alternator or there is stator damage.
7. TURN HIGH BEAMS AND BLOWER MOTOR ON, IDLE ENGINE: After a few seconds, the 
EXP will ask you to turn on the accessory loads. It will determine if the charging system is 
able to provide enough current for the demands of the electrical system.
IMPORTANT: Turn on the high-beam headlights, the blower to high and the rear defogger. 
Don’t use cyclical loads such as air conditioning or windshield wipers.
8. TESTING ALTERNATOR AT IDLE, LOADS ON: The analyzer will determine if the charging 
system is able to provide sufficient current for the demands of the vehicle’s electrical 
system.

NO PROBLEMS The system is showing normal output from the alternator. No problem detected.
NO OUTPUT
The alternator is not providing charging current to the battery. 
√ Check the belts to ensure the alternator is rotating with the engine running. 
Replace broken or slipping belts and retest. 
√ Check all connections to and from the alternator, especially the connection 
to the battery. If the connection is loose or heavily corroded, clean or replace 
the cable and retest. 
√ If the belts and connections are in good working condition, replace the alterna-
tor. (Older vehicles use external voltage regulators, which may require only 
replacement of the voltage regulator.) 
LOW OUTPUT
The alternator is not providing enough current to power the system’s electrical 
loads and charge the battery.
√ Check the belts to ensure the alternator is rotating with the engine running. 
Replace broken or slipping belts and retest.
√ Check the connections from the alternator to the battery. If the connection is 
loose or heavily corroded, clean or replace the cable and retest.
HIGH OUTPUT
The voltage output from the alternator to the battery exceeds the normal 
limits of a functioning regulator.
√ Check to ensure there are no loose connections and that the ground connection 
is normal. If there are no connection problems, replace the regulator. (Most 
alternators have a built-in regulator requiring you to replace the alternator. In 
older vehicles that use external voltage regulators, you may need to replace 
only the voltage regulator.)
The regulator controls voltage output based on the battery voltage, under-
hood temperature, and vehicle loads used. In other words, it controls the 
maximum voltage the system can produce based on the current needs and 
amount of current that can be produced by the spinning of the rotor in the 
alternator. The normal high limit of a typical automotive regulator is 14.5 
volts +/–0.5. Refer to the manufacturer specifications for the correct limit, 
which may vary by vehicle type. 
A high charging rate will overcharge the battery and may decrease its life and 
cause it to fail. If the battery test decision is REPLACE and the charging system 
test shows a HIGH OUTPUT, check the battery’s electrolyte levels. A symptom 
of overcharging is battery fluid spewing through the vent caps, which causes low 
electrolyte levels and will harm the battery.

Chapter 7: Cable Drop Test
If the test results for the starter or charging systems indicate that there may be a problem, you may want 
to perform the Cable Drop Test to determine if it is due to worn cables or bad connections between the 
battery and the alternator or starter. Worn cables or bad connections create higher resistance, which 
causes a drop across the circuit. The voltage drop reduces current carrying capability that displays the 
same symptoms as a weak alternator or starter and causes premature battery failure.
There’s no need to run the engine. The Cable Drop Test uses Midtronics’ conductance technology to 
send a signal through the circuit at the component under test. The EXP then simultaneously calculates 
voltage drop on the  positive (+) and negative (–) sides of any circuit as well as the total voltage drop. 
The amperage range for each of the four tests is 0 to 1000 A. When you change the setting from the 
factory defaults, the EXP will store your setting in memory for your next test. 
There are three preset tests:
• BATTERY GROUND
• STARTER CIRCUIT
• ALTERNATOR CIRCUIT
A fourth test, OTHER CIRCUIT, tests other grounds and circuits against your specified amperage 
capacity.
The test requires two test lead connections, as shown in Figure 17: 
• Battery test leads at the component’s output lead (the B+ or output screw on the 
alternator) and the component’s housing as ground 
• DMM test leads at the battery terminals
NOTE: The test requires a complete circuit. If you’re testing a system with a remote 
solenoid, you can test from the battery to the solenoid, but not from the battery to the 
starter.

Chapter 13: Troubleshooting
If you have problems with the display or the Midtronics printer, try these troubleshooting suggestions:
The Display Does Not Turn On
• 
Check the connection to the vehicle battery.
• 
Press the POWER button.
• 
The vehicle’s battery may be too low to power the analyzer (below 1 volt). Fully charge 
the battery and retest. 
• 
The analyzer’s 6 AA batteries may need to be replaced. Follow the directions in 
Chapter 14: EXP Internal Batteries and replace the batteries (alkaline recommended).
• 
If troubleshooting does not solve the problem, contact Midtronics at 1-800-776-1995 to 
obtain service. See “Patents, Limited Warranty, Service” for more information.

Data Will Not Print
• 
If the IR transmitter and receiver are not aligned, all the data may not print. The infrared 
ports on the top of the analyzer and on the printer below the MODE button should be 
pointed directly at each other. The maximum distance for reliable transmission between 
the ports is 17 in (45 cm).
 
To realign, press the END button to cancel the print job. Verify alignment between the 
analyzer and printer; then try to print the test results again.
• Make sure the printer is on. The printer shuts off after 2 minutes of inactivity to conserve 
the batteries. To turn the printer on, briefly press the MODE button. The green STATUS 
light should turn on. Make sure you are using the Midtronics printer. Other printers may 
not be compatible.

• Direct sunlight interferes with infrared data transmission and receiving. If the printer is 
not receiving data, remove the printer and EXP from direct sunlight. If the printed charac-
ters are not clear or are partially missing, recharge the battery and reprint.  
• 
If you are unable to print after ensuring the analyzer is functioning, the printer is on, the 
batteries are good, and the IR transmitter and receiver are aligned, check the printer 
manual for further instructions or call Midtronics at 800-776-1995 for assistance. (See 
“Patents, Limited Warranty, Service” for more information.)

Chapter 14: EXP Internal Batteries
The EXP uses 6 AA, 1.5-volt batteries (alkaline recommended) to allow testing of batteries down to 
1 volt and supply power while the menu is active. The analyzer can test batteries down to 5.5 volts 
when the internal batteries are not functioning. 
Battery Power Indicator
The square in the upper left corner of the display indicates the charge level of the battery pack. The 
square is black when the battery pack is fully charged. It gradually changes to white as the charge 
level declines. The EXP will display a warning message when the batteries need replacing.
