The measurement data can be directly exported from the USB drive and managed on the computer. The upper computer management software can be used to browse, edit, print (A4 format) standard format test reports, backup, and other functions of the instrument data;
The 15 instruments are equipped with RS232/485 communication interfaces and can read the energy data of a multifunctional energy meter (according to the national standard 645 protocol);
16. Minimum starting current of 1mA, high supply and high timing, and identifiable wiring even when unloaded;
17. Clock calibration for electronic watches: It can verify the clock accuracy of multifunctional electronic watches;
18. Support barcode scanning gun, automatically enter electricity meter code (optional function);
19. Use a 485 or infrared light sensor to read the active and reactive power base values of the multifunctional energy meter, including peak, flat, valley, and total. Support the national standard DL645 protocol;
20. Support carrier meter reading (optional function);
21. Handheld structure, anti slip wrist guard, drip plastic button, flame-retardant shell, humanized design, safer and more reliable on-site use.
22. Select a dedicated tablet handheld mobile terminal, which uses wireless WIFI communication to perform real-time operation and control of the on-site inspection instrument for the electric energy meter. The tablet handheld operating platform and the verification instrument host interface are completely consistent, whether the user operates the host alone or wirelessly through the tablet handheld, the operation method is exactly the same, and there is no differentiation in actual operation.
