Operating Instructions
WARNING: Risk of electrocution. High-voltage circuits, both AC and DC, are very
dangerous and should be measured with great care.
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.
AC VOLTAGE MEASUREMENTS
WARNING: Risk of Electrocution. The probe tips may not be long enough to contact the
live parts inside some 240V outlets for appliances because the contacts are recessed deep
in the outlets. As a result, the reading may show 0 volts when the outlet actually has voltage
on it. Make sure the probe tips are touching the metal contacts inside the outlet before
assuming that no voltage is present.
CAUTION: Do not measure AC 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 600 VAC position.
2.
Insert the black test lead banana plug into the negative COM jack.
Insert red test lead banana plug into the positive V jack.
3.
Touch the black test probe tip to the neutral side of the circuit.
4.
Touch the red test probe tip to the "hot" side of circuit.
5.
Read the voltage in the display.
6.
If the reading is less than 200V, switch to the 200V range to improve
resolution.
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 600VDC 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.
5.
If the reading is less than the maximum of a lower range, switch to that
range to improve resolution.
