4) Connect the common test wire and then the live test
wire during connection. Remove the live test wire
first during disconnection.
4.8 Measurement Of DC Voltage
WARNING
There is the risk of electric shock.
Pay special attention to avoid electric shock
when measuring high voltages.
Do not input any voltage of over DC1000V,
which may damage the internal circuit though
a higher voltage may be displayed.
4.8.1 Plug the black probe into the
COM
jack and the red
probe into the V jack.
4.8.2 press the “
RANGE
” key to select the auto or manual.
4.8.3 Connect the test probes to the voltage source or load
in parallel for measurement.
4.8.4 Take a reading in the main display area of the LCD.
The polarity indication will show the polarity of the
terminal connected by the red probe.
Note:
1) At the low voltage range, unsteady readings will appear
before the test probes contact the circuit. This is normal
because the meter is highly sensitive. When the test
probes contact the circuit, the true reading will be
displayed.
2) In the manual range mode, if the LCD displays “O L”
or “-O L” only, it means the measurement has exceeded
the range and a higher range should be selected.
3) In the manual range mode, if the scale of the measured
value is unknown beforehand, the highest range should
be set and then lowered down gradually.
4.9 Measurement Of AC Voltage
WARNING
There is the risk of electric shock.
Pay special attention to avoid electric shock
when measuring high voltages.
Do not input any voltage of over AC750V rms,
which may damage the internal circuit though
a higher voltage may be displayed.
4.9.1 Plug the black probe into the
COM
jack and the red
probe into the V jack.
4.9.2 Set the range selector to the V range position.
4.9.3 Press the “
RANGE
” key to select the auto or manual
mode.
4.9.4 Connect the test probes to the voltage source or load
in parallel for measurement.
4.9.5 Take a reading in the main display area of the LCD.
Note:
1) At the low voltage range, unsteady readings will appear
before the test probes contact the circuit. This is normal
because the meter is highly sensitive. When the test
probes contact the circuit, the true reading will be
displayed.
2) In the manual range mode, if the LCD displays ‘O L’ only,
it means the measurement has exceeded the range and
a higher range should be selected.
3) In the manual range mode, if the scale of the measured
value is unknown beforehand, the highest range should
be set and then lowered down gradually.
