Procedure :
Ensure that the measured circuit is turned OFF and that no
voltage is present in it.
①
Connect the EARTH (ground) lead (Black) to the EARTH (E)
terminal and the LINE lead (Red) to the LINE (L) terminal. Also
connect the GUARD terminal if required.
(When using GUARD, also see
5-7 Using the GUARD Terminal
.)
②
Set the function switch to the desired test voltage function.
③
Connect the test leads to the object measured.
④
If a voltage of 30 V or more is present while the object is not
measured, the high voltage warning is displayed and the buzzer
beep is generated. In this case, the measurement cannot be
started by pressing the TEST button. If this happens, check the
power supply to the object measured.
⑤
Press and hold the TEST button for more than 2 seconds to
start the voltage output. When the function uses a voltage of
1000 V or more, intermittent buzzer beeps are generated during
measurement to warn about the high voltage generation.
⑥
Read the value or bar graph on the display.
⑦
To stop the measurement, press and hold the TEST button for
more than 1 second. The value displayed at the moment the
measurement is stopped is held automatically.
⑧
The object measured may be charged even after measurement.
Ensure that it is free of voltage charge by referring to
5-4
Discharge Function
and be sure to disconnect the LINE lead
before the EARTH (ground) lead.
