The “
” besides the probe jack indicates that the input
voltage or current should not exceed the specified limits
to protect the internal circuit.
3
Before measurement, turn the function/range switch to
the desired range.
Direct voltage measurement
1
Insert the red probe into the “
VΩmA
” jack and the black
one into the “
COM
” jack.
2
Turn the function/range switch to “
” and connect the
probe to the power supply or load to be measured. The
polarity touched by the red probe will be on the display.
WARNING
1. If you do not know the measured voltage range in advance,
set the function/range switch to the maximum range, and then
gradually turn to smaller ranges until satisfactory resolution.
2. If the display shows “
OL
”, this indicates an overrange
measurement, and the switch should be set to a higher range.
3. Do not input a voltage of more than 600V, it is capable of
indicating a higher voltage, but with the risk of damaging the
inside circuit.
4. When taking the measurement of high voltage, pay special
attention to avoid an electric shock.
Alternating voltage measurement
1
Place the red probe into the “
VΩmA
” jack and the black
one into the “
COM
” jack.
2
Turn the function/range switch to “
v~
” and connect the
probe to the power supply or load to be measured.
Note: Refer to point 1, 2, 3, and 4 for direct voltage
measurement.
