WARNING
Beware of Electrocution.
Pay special attention to avoid electric shock
when measuring high voltage.
Do not input the voltage which more than
600V rms AC.
4.12 Measuring AC Voltage
4.12.1 Plug the black test lead into the COM jack and
the red test lead into the INPUT jack.
4.12.2 Set the rotary selector to V position to make
the meter get into AC V range.
4.12.3 Auto range mode or manual range mode can
be selected by pressing the “RAN” button.
4.12.4 Connect the test leads to the voltage source or
load terminals for measurement.
4.12.5 Take the reading on the LCD.
Note:
1) At small voltage range, unsteady readings may
appear before the test leads contact the circuit.
This is normal because the meter is highly sensitive.
When the test leads contact the circuit, the true
reading will be shown.
2) At the manual range mode, when only 'OL' is shown
on the LCD, it means the measurement has exceeded
the range. A higher range should be selected.
3) At the manual range mode, when the scale of the
value to be measured is unknown beforehand, select
the highest range first and lower the range gradually.
4) “ ” means the maximum input voltage is 600V rms AC.
5) If the test result is more than 610V rms AC, symbol
“OL” will be displayed on LCD and the build-up
buzzer will sound.
