5-3. How to Make Measurements
_
WARNING
1. To avoid electrical shock hazard and/or damage to the
meter, do not measure voltages that might exceed 600V
above earth ground.
2. Before using the instrument, inspect the test leads,
connectors, and probes for cracks, breaks, or grazes in
the insulation.
DC Voltage Measurement
1. Plug the red test lead into the "V Ω mA" jack and the
black test lead into the "COM" jack.
2. Set the RANGE switch to the desired DCV position. If
the voltage to be measured is not known beforehand,
set the switch to the highest range and reduce it until a
satisfactory reading is obtained.
3. Connect the test leads to the device or circuit being
measured.
4. Turn on the power of the device or circuit being
measured. The voltage value will appear on the digital
display along with the voltage polarity.
