2) Buzzer Alarm
a.The buzzer beeps once (about 0.25s) at any valid press of buttons or turning of the function dial.
b.The buzzer beeps continuously when the input voltage or current is over range.
3) Low Battery Detection
When the battery voltage is <4.6V, "
" is displayed. After the symbol lasts for 20s, the meter
displays "Lo.bt" and automatically shuts down after 60s.

Accuracy: ± (a% of reading + b digits), 1 year calibration period
Ambient temperature: 23°C ± 5°C; ≤80%RH
Temperature coefficient: To ensure measurement accuracy, the operating temperature should be
within 18°C~28°C and the fluctuation range should be within ±1°C. When the temperature is <18°C
or >28°C, add temperature coefficient error: 0.1 x (specified accuracy)/°C.

±(2.5%+35)
1) Clean the meter casing with a soft cloth and mild detergent.
Do not use abrasives or solvents!
2) If there is any malfunction, stop using the meter and send it
for maintenance.
3) The maintenance and service must be implemented by
qualified professionals or designated departments.
2. Battery/Fuse Replacement
1) Turn the function dial to the "OFF" position, and remove the test leads from the input terminals.
2) Unscrew and remove the battery cover.
