Operating Instructions
WARNING:
Risk of electrocution. High-voltage circuits, both AC and DC,
are very dangerous and should be measured with great care.
If “1” 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 con-
nected 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.
NOTE:
To extend the battery life of the meter the backlight will automatically
turn off in approximate 30 seconds.
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 position.
2. Insert the black test lead banana plug into the negative
COM
jack and
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 and red
test probe tip to the positive side of the circuit.
4. Read the voltage in the display. If polarity is reversed, the display will
show (-) minus sign before the value.
5. Reset the function switch to successively lower positions to obtain a
higher resolution reading.
