X. Maintenance
Warning: Before opening the rear cover or battery cover,
switch off the power supply and remove the test leads.
1. General Maintenance
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.
3) Replace with 4×1.5V AAA batteries, observing correct polarity.
Or replace the blown fuse (specifications: F1 Fuse 630mA 250V Φ5x20mm ceramic tube;
F2 Fuse 20A 250V Φ5x20mm ceramic tube)
4) Secure the battery cover and tighten the screw.

12) Electromagnetic compatibility:
RF=1V/m, overall accuracy = specified accuracy + 5% of range
RF>1V/m, no specified calculation
2. Electrical Specifications
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.
Overload protection: 1000V
Input impedance: About 10MΩ
Frequency response: 45Hz~400Hz, true RMS display
Accuracy guarantee: 5%~100% of range
AC crest factor: The full-scale value of the AC crest factor can reach 3.0. If the crest factor of a
non-sinusoidal wave is ≤3.0, no additional error will be added. The accuracy of other crest factors
beyond the range are not assessed.
Overload protection: 1000V
