WARNING:
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 meter is not in use.
2. If “
OL
” appears in the display during a measurement, the value exceeds the range you
have selected. Change to a higher range.
DC VOLTAGE MEASUREMENTS
CAUTION:
Do not measure DC 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 green
VDC
position.
2. Insert the black test lead banana plug into the
negative
COM
jack.
Insert the red test lead banana plug into the
positive
V
jack.
3. 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.
4. Read the voltage on the display.
