4. Verify the errors of various mechanical turntable or electronic single-phase energy meters without power outage or changing the wiring conditions of the energy meter;

5. The energy accumulation function can assess the electricity consumption of electrical equipment during a certain period of time, providing a calculation basis for energy conservation and consumption reduction of electrical equipment;

6. Without voltage connection, only current and pulse signals can be connected to quickly troubleshoot centralized meter reading issues for users based on the set values;

7. Powered by lithium batteries, it can work continuously for 18 hours when the backlight is turned off, and for 8 hours when the backlight is turned on. It does not require an external power supply and has a low power indicator; Lithium batteries can be used as clamp ammeters without voltage connection;

8. Equipped with high current clamps to measure the transformation ratio and polarity of low-voltage CT;

9. Equipped with pulse output, convenient for inspection;

10. It can store 500 sets of detection data, making it convenient to query and store data sets;

11. The instrument is equipped with a built-in clock chip that can accurately record the detection time for future reference;

12. Data can be uploaded to a PC and browsed, queried, managed, and reports can be printed using the accompanying WINDOWS system software;

13. Ultra small streamlined structure, anti drop wristband design, handheld, small size, light weight;

14. A single-phase load box can be optionally selected. When the tested meter is not loaded, it can directly output 5A current to calibrate the energy meter;

15. Optional upgrade CJJL-550B, measuring 21st harmonic and waveform.
