4. Copper Testing
4.1 AutoTests OneCheck Copper
Purpose
The OneCheck test is used to determine whether the DVOM (Voltage, Re-
sistance), Capacitance (Loop Length), and Balance pass on the F2/Drop section
of the loop. This test requires open pairs on the far end.
Note: High Voltages on the line can lead to false test results or damage to
the instrument. The test set performs a voltage measurement prior to
starting a test; if there is voltage present, a popup warning message will be dis-
played.

5.0 Additional Copper Tests
5.1 Voltage
Purpose
MultiMeter is used to measure Voltage. The presence of excessive AC
voltage is often due to induction from the AC power grid. The presence of
any DC voltage is an indication of a resistive coupling (cross) to one or
more working pairs (with CO battery).
