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,
Resistance" can not be measured and with no readings on the displays.
If one auto test is started and "Loop Resistance" is less than 40KΩ, "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.
