3. OPERATING INSTRUCTIONS
Risk of electrocution. High-voltage circuits, both AC and DC,
are very dangerous and should be measured with great care.
1. Always turn the function switch to the OFF position when the
multimeter is not in use.
2. If "OL" appears on screen during a measurement, the value
exceeds the range you have selected. Choose a higher range.
3.1 DC voltage measurements
Do not measure DC voltages if a motor on the circuit is being
switched ON or OFF. Voltage surges may occur and damage
the multimeter.
1. Set the function switch to the VDC position.
2. Insert the black test lead banana plug into the
negative COM terminal.
Insert the red test lead banana plug into the
positive + terminal.
3. Apply the test probes to the points of the circuit
to be tested.
4. The voltage measured is displayed on screen.
