It is applicable to test and measuring circuits connected to the distribution part of the building’s
low-Voltage MAINS installation.
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 °C” 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.
The meter has the function of ACV/DCV automatic identification (voltage ≥0.5V). If you want to measure voltage less than 0.5V,
press the Select Button to toggle the AC and DC voltage to lock the measurement mode: After pressing the SELECT button,
the meter no longer has the function of ACV/DCV automatic identification, unless you turn the range switch or restart the meter!
Note:
•
Do not measure voltage above 600Vrms. Although it is possible to measure higher voltage, it may damage the meter and
hurt the user! If the LCD displays “OL”, it indicates that the voltage is over range. The input impedance of the meter is 10MΩ.
This load effect may cause measurement error when measuring high impedance circuits. If the measured impedance is
≤10kΩ, the error can be ignored (≤0.1%).
• Be cautious to avoid electric shock when measuring high voltage.
• Test known voltage before use to confirm if the meter functions properly!
