1) Long press “ ” key to turn on the power.
2) Insert the red probe into the “ ” jack and the black
probe into the “COM” jack.
3) Touch the test lead tips together to check if they are
connected normally. The indicator light should turn
green and the buzzer sounds.
4) Press “
” key to switch to “ ” function. Press ”
” to switch between AC voltage and DC voltage.
5) When measuring AC mV, connect the two tests leads
to the neutral and live wires respectively (red to live,
black to neutral). After the reading stabilizes, record
the reading from the screen. The frequency will be
displayed at the same time.
6) When measuring DC mV, connect the red test lead
to the positive electrode and the black test lead to
the negative electrode. After the reading stabilizes,
record the reading from the screen. Note: If the result
is negative, it means the test leads are connected
inversely. To achieve a positive result, reconnect the
test leads to the correct electrodes.
7) When the measurement is completed, disconnect
the test leads from the measured object.
WARNING
1. A voltage higher than 250V cannot be measured
otherwise the meter may be damaged.
2. Pay special attention to safety when measuring
high voltage to avoid electric shock or personal
injury.
