DMM Tests
Warning
When connecting to the line, especially when using
crocodile clips, special care must be taken as high voltages
may be present on the line and there may be a danger of
electrocution.
Caution: TDR/DMM Tests
When performing Capacitance and Load Coil tests make
sure that voltage is NOT present on the line, if a voltage is
present on the line you may damage
The Current test is intended for low DC current
measurement only. It is protected by a 400mA fuse.
The TDR/DMM module has protection devices fitted at
manufacture that cannot be reset by the user. If the
protection devices are activated
returned to Agilent Technologies for repair.

You can also run a DMM test from the Auto Test Mode
screen. See
DMM (Digital Multimeter) and TDR (Time Domain
Reflectometer) tests are used to test the Electrical Layer of
the local loop.
The DMM test enables you to:
