Detection of voltage and mass wires
• put the red probe in the socket
only one probe is enough
• turn the main switch to the LIVE position
• put the tester on the cable
• if a quick, intermittent buzzer sound appears
and the red diode above the screen flashes
and the display shows symbol:
- - -
it means
a current cable with voltage
• if a slow, intermittent buzzer sound appears
and the red diode above the screen flashes
and the display shows the symbol: it means
the negative wire (ground).
Non-Contact Voltage Detection (NCV)
• this function does not require the use of probes,
the measurement is carried out by the built-in
NCV detector in the upper part
• turn main switch to NCV position
• bring the detector closer to the cable or the socket
• if an intermittent buzzer sound appears and the
red diode above the screen flashes and the display
shows a symbol of bars (one, two, or three

depending on the signal strength): it means that
the tested circuit is live.
• note, the signal strength depends on many factors,
such as insulation thickness, depth of cable hiding,
environmental humidity and electrical noise.
Therefore, if the detector is not signaling voltage,
it does not mean that it is not there. If you think
the cable may be live, retest with another method.
Diode test
• put the black sampler in the slot
• put the positive, red test probe in the socket
• turn the main switch to position
• put the testers in parallel to the diode circuit
(red at the input), if the buzzer gives a signal,
it means working diode
• to measure the diode voltage, press the SEL
button, the diode icon will appear on the screen.
Take the measurement, the correct voltage value
is 500-800mV.
• if the coil circuit is broken or the polarity is reversed,
the meter shows OL.
• when measuring diodes, disconnect the power from
the device and discharge the capacitors
• after taking measurements, disconnect the testers
from the circuit
