Operation
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.
NOTE: On some low AC and DC voltage ranges, with the test
leads not connected to a device, the display may show a
random, changing reading. This is normal and is caused by the
high-input sensitivity. The reading will stabilize and give a proper
measurement when connected to a circuit.
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 highest 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 in the display. Reset the function switch to
successively lower V
DC positions to obtain a higher
resolution reading. The display will indicate the proper
decimal point and value. If the polarity is reversed, the
display will show (-) minus before the value.
