(3) Connect the Earth cord (black) to the Earth terminal of the circuit under test.
(4) Put the tip of the Line probe (red) to the circuit under test.
Then press the Test button. The buzzer sounds intermittently during
measurement when a range other than 500V(250V) range is selected.
(5) The measured value will be displayed on the LCD, and it remains displayed on
the LCD after a measurement.
(6) This instrument has Auto-discharge function. Keep the test leads connected
to the circuit under test and release the Test button when measurements end.
The auto-discharge function operates to discharge the electrical charges on
the circuit under test. Confi rm that the voltage monitor shows 0V.
# DANGER
● Do not touch the circuit under test immediately after testing.
Capacitance stored in the circuit may cause electric shock.
● Leave test leads connected to the circuit and never touch the circuit until the
discharge completes.
Auto-discharge function
This is a function to discharge capacitance stored in the circuit under test
automatically after testing. Discharge condition can be checked on the voltage
monitor. This function will be canceled when removing the test leads 2 sec. or
more before discharge completes.
CAUTION
Turn off the breaker of
the circuit under test.
