4.13 Measuring DC Voltage
WARNING
Beware of Electrocution.
Pay special attention to avoid electric shock
when measuring high voltage.
Do not input the voltage which more than
600V DC.
4.13.1 Plug the black test lead into the COM jack and
the red test lead into the INPUT jack.
4.13.2 Set the rotary selector to at the V range position.
4.13.3 Press the“SEL” button to turn to DC V range.
Auto range mode or manual range mode can be
selected by pressing the “RAN” button.
4.13.4 Connect the test leads to the voltage source or
load terminals for measurement.
4.13.5 Take the reading on the LCD. The polarity
symbol denotes the polarity of the end
connected by the red test lead.
Note:
1) At small voltage range, unsteady readings will
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) Under the manual range mode, when only
‘O L ’ o r ‘- O L’ is shown on the LCD, it means the
measurement has exceeded the range. A higher
range should be selected.
3) Under 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 DC.
5) If the test result is more than 610V DC, symbol “O L”
will be displayed on LCD and the build-up buzzer
will sound.
