2.
Check that voltage is not applied to the circuit under
test. Measure the voltage according to chapter 5,
“VoltageMeasurement.”
3.
Confirm the voltage that can be applied to the DUT,
and set the range switch to the appropriate range (rated
measurement voltage).
• Youcanonlychangetherangewhenyouturn
off both the measurement switch and the probe’s
remote switch.
• Thereisanemptyrangebetweenthe500Vand
1000Vpositions.Notethatiftherangeswitchisset
to the empty range, insulation resistance will not be
measured even when you press the measurement
switch.
• Whentherangeswitchissettothe1000V,an
intermittent buzzer sounds to warn you of the high
voltage output range.
• Toswitchbetweenthe125Vand100Vranges,set
therangeswitchtothe125V/100Vposition,and
hold down SELECT for at least 1 second. The set
voltage appears on the screen.
4.
Connect the probe (black) connected to the EARTH
terminal to the ground terminal of the circuit under test.
Ifthevoltageis30Vorhigher,alivecircuitwarning
is indicated with a blinking
, buzzer, and red
backlight. When the live circuit warning is in effect, the
measurement button is disabled.
5.
Apply the tip of the probe (red) connected to the LINE
terminal to the circuit under test, and press both the
measurement switch or the probe’s remote switch.
Measurement will not start if you press only one of the
switches.
