Fig 27: “ Distance ” results menu
Caution:
After setting “ Function ” item as “ DMM ” , directly pressing “ AUTO TEST ” key
can start a DMM test.
Pay attention to the measurement range descriptions in “ Reference ” menu of
the tester to ensure not to connect the out-ranged signals.
If one auto test is started and a signal with its voltage (>2V) is detected by the
tester,
“ Loop Resistance ” , “ Loop Capacitance ” and “ Isolation
Resistance ” can not be measured and with no readings on the displays.
If one auto test is started and “ Loop Resistance ” is less than 40K Ω , “ Loop
Capacitance ” and “ Isolation Resistance ” can not be measured.
In “ Loop Resistance ” , “ Loop Capacitance ” and “ Isolation Resistance ”
testing mode, the test can not be performed if there is a signal with its voltage
(>2V) is detected in the line.
The results in “ Distance ” menu are described in Table 20.
