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.
