4-3.mV Voltage Measurements
CAUTION:
Do not measure mV voltages if a motor on the circuit is being switched ON or OFF. Large
voltage surges may occur that can damage the meter.
1. Set the function switch to the
mV AC/DC position.
2. Press the MODE button to indicate “ DC ” or “ AC ”.
3. Insert the black test lead banana plug into the negative COM jack; Insert the red test lead banana
plug into the positive V jack.
4. Touch the black test probe tip to the negative side of the circuit; Touch the red test probe tip to
the positive side of the circuit.
5. Read the mV voltage in the display.
6. Press the
HZ/% button to indicate “ Hz ”.
7. Read the frequency in the display.
8. Press the
Hz/% button again to indicate “ % ”.
9. Read the % of duty cycle in the display.
