Hongkong Sinotie International Ltd.

1.Starting test and creeping test 2.Measuring the different constant meters synchronously. 3.With the protect function of overload, short voltage circuit and open current circuit. 4.The testing software with friendly windows 2000 and xp interface, include functional module of all kinds of modern energy meter needed, to reality error test, harmonic test, demand test, influence test. 5.The stored testing data can be transferred to multi-format for other program using

Snt 1100 single phase meter test bench is widely used in power utilities,¡émeter manufacturer,¡émeasurement/quality test lab and other enterprises to test single phase energy meter.

Measure normal parameter of power line: Vrms, irms, frequency Active power, reactive power, apparent power Phase angle between voltage and current Power factor Calibrate single phase meter; Measure harmonic of voltage and current; Measure waveform of voltage and current; Measure current transformer¡¡¥s ratio (option); Energy accumulation test; Built-in clock, record testing time exactly; Store, check and transmit the measured data; Connected to pc, reading recorded data and real-time measured data by pc; Alarm when the tested voltage and current over the testing range; Connected to portable printer (option).

Features: 1. Check the error of active and reactive of watt-hour meter at the same time, and meanwhile check the error of main and secondary meter in the same circuit. 2. Display the electrical constants such as: voltage, current, power, power factor, phase and frequency and etc. 3. Measure ct ratio, wave form display. 4. Measure 2-51 voltage and current harmonics. 5. Judge wrong wiring. 6. Measure the baud rate for multi-function energy meter and meter number reading. ¦ct secondary loading function. 8. Automatically correct the clamp error.
