ETDR-10
Cable Fault Locator
Applications
The ETDR-10 is purpose designed for
balanced telecommunications cable.
Seven test modes offer fast and accurate
fault location procedures for finding cable
discontinuities at distances of up to 20 km.
Another feature is the possibility of com-
paring measured cable parameters with
results stored in 10 memory locations.
The ETDR-10 has dedicated keys for the
most frequently used functions.
All faults are clearly identified from open
circuits to wet joints.
It is a small hand-held instrument for
measuring TDR cable parameters. In
conjunction with the EPR-42S printer
it is suitable for printing measurement
protocols.
All cable faults are clearly identified on a
large calibrated display.
