Do not use the meter if the rear cover is not covered up, or it will pose a shock hazard!
Before use, please check and make sure the insulation layer of the meter and test leads is in good condition
without any damage or broken wires. If you find the insulation layer of the meter housing is significantly
damaged, or if you think the meter cannot function property, do not use the meter.
When using the meter, your fingers must be placed behind the finger guard ring of the test leads.
Do not apply voltage over 600V between any meter terminal and earth ground to prevent electric shock and
damage to the meter.
Be cautious when the measured voltage is higher than 60V (DC) or 30Vrms (AC) to avoid electric shocks
The measured signal is not allowed to exceed the specified limit to prevent electric shock and damage to the
meter!
The range switch should be placed in the corresponding position during measurement.
Never change the range setting when measuring to avoid damage to the meter!
Do not change the internal circuit of the meter to avoid damage to the meter and user!
When the symbol appears on the LCD, please replace the batteries in time to ensure measurement
accuracy.
Do not use or store the meter in high temperature and high humidity environments. The performance of the
meter may be affected.
Clean the meter casing with a damp cloth and mild detergent. Do not use abrasives or solvents!
Safety symbol description
4. Operating Instructions
The meter has the function of battery self-checking, and can complete the battery status detection within 2
seconds at the moment of booting:
a) When the supply voltage is >2.7V, the indicator on the top of the meter lights up green for 2 seconds,
indicating that the power is sufficient, and the meter enters the normal measurement mode accompanied by
one beep.
b) When the supply voltage is within 2.4V~2.7V, the indicator on the top of the meter lights up yellow, and the
low battery symbol appears on the LCD.
c) When the supply voltage is <2.4V, the indicator on the top of the meter lights up red for 2 seconds, and then
the meter powers off. It can only be used after replacing the batteries.
4.1 DC/AC Voltage Measurement (Picture 1)
1) Tum the range switch to the AC voltage position;
2) Insert the red test lead into the ” v Ω “jack, black into the “COM” jack, and make the probes in contact with both
ends of the measured voltage (parallel connection to the load);
3) Read the test results on the display.
