6. Operating Instructions

Always ensure the meter is set to the correct function and range before making any measurements. Connect test leads to the appropriate input jacks.

6.1 AC/DC Voltage Measurement

1. Insert the red test lead into the VΩHzT+ jack and the black test lead into the COM jack.
2. Turn the rotary switch to the V~ (AC Voltage) or V- (DC Voltage) position.
3. If measuring AC voltage, press the SELECT button to toggle between AC and DC if necessary (for combined V~ / V- position).
