OPERATING INSTRUCTIONS
WARNING: Extreme care should be taken when reading
high voltages. DO NOT exceed maximum voltage for
which the meter is designed.
DC VOLTAGE MEASUREMENT
1. Set function switch to V position
2. Set range switch to desired position. If magnitude
of voltage is unknown beforehand, set the switch
to its highest range and then reduce until
satisfactory reading is obtained.
3. Connect test leads across the source or load under
measurement. The polarity of the RED lead
connection will be indicated as well as the voltage.
4. When the range switch is set to the 500V position, “HV”
will appear on the display, to remind you of a high
voltage measurement. Special care should be taken.
AC VOLTAGE MEASUREMENT
1. Set function switch to V position.
2. Set range switch to desired position. Measurement
reading can be obtained at 2V and 20V positions,
but accuracy is not guaranteed.
3. Connect test leads across load or source under
measurement. Read voltage value on display.
4. When the range switch is set to the 500V position, “HV”
will appear on the display, to remind you of a high
voltage measurement. Special care should be taken.
