Lower limit value
icon
The symbol appears when the upper limit value is set,
and the symbol
appears when the lower limit value is
set.
3 Measured
resistance value
Represent the value of a resistance flowing between the
HIGH and LOW terminals.
4 Test time
elapsed
When the testing time is set, countdown starts from the
time set, and is displayed. When the testing time is set to
OFF, the time elapsed after the start of the test is
displayed.
If the elapsed test time exceeds 999 s, "---" is displayed,
but the voltage continues to be output.
5 Test voltage
range
Indicates the test-voltage value.
6 TEST
Remains lit during the test.
Danger lamp
Indicates that a voltage is being output. This lamp remains lit as long as a
voltage of at least 50 V is being applied to the output terminal in the
insulation resistance mode.
Analog voltmeter
Does not move in insulation resistance mode.
External I/O
The
TEST
――――――――
signal is turned ON when
TEST
on the fluorescent indicator lights
up. The
