GF312B three-phase Energy Meter Calibrator With Printer
 

(Accuracy class 0.05/0.1)

Application

It is suitable for measuring power grid companies test center, power supply company power supply management, power metering, technical supervision department, industrial and mining enterprises, petroleum, chemical industry, electric power measure of the department.

Main functions and features:

1, To check single-phase and three-phase induction type, mechanical and electrical meter; And can also check two different constants of watt-hour meter;

2, real-time field measurement three-phase voltage, current, active power, reactive power, phase, power factor, frequency, power, and a screen all measured parameters;

3, To measure CT variable ratio; Display voltage current vector diagram and check the wiring errors, giving the wrong wiring state power loss (Complement factor);

4, the way of power supply, can external ac power supply, also can line voltage power supply;

5, dynamic tracking load changes, the voltage, current fluctuating site can also accurate calibration watt-hour meter error;

6, divided into direct measurements and current clamp measurement, good stability, safety and reliability;

7, optional 5 A, 20 A, 100 A, 500 A, 1000 A, 2000 A current clamp;

8, To measure 2 ~ 63 times harmonic content, showed great harmonic wave diagram and the figure, the harmonic analysis;

9, with micro printer, but the spot printing; And it can be selected barcode scanners automatically scans, electric table;

10, with intelligent photoelectric sampler, convenient to the pulse to adopt several watt-hour meter;

11, big screen color liquid crystal display, simple operation, convenient; The large capacity memory, storing 5000 sets of data;

12, with RS232 and USB interface, which can be the scene of the measurement data storage will be turning to the computer analyzed with;
