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 500V 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

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.
