3-Phase AC/DC Standard Power & Indicating Meter
Capable of testing all types of AC ammeter, AC voltmeter, DC ammeter, DC voltmeter, power meter, AC phase meter, power factor meter and frequency meter.
Acts as 3-phase AC standard source, as 3-phase DC standard source, 3-phase power standard source and 3-phase harmonic standard source.
These built-ins are voltmeter, ammeter, phase meter, power meter, power factor meter, harmonic meter. All meters above are in high precision (0.05 class)
Realize closed loop control on current outputs, voltage output, power output, phase output and harmonic output guaranteeing its low drift and its steady annual stability.
2-19 times harmonic output, standard output in 0.1 class; while 20-31 times are those standard outputs in 0.2 class
Working mode: Meter Calibration Output Mode, Standard Source Output Mode
Built-in RS232 port allows software upgrade and calibrated date transfer without opening up the external box of the equipment.
Software possesses self-calibration function, users can calibrate all kinds of electric measurement parameters values without opening up the external box of the equipment.
Automatic Faults Test of software figures out where faults occur in the relay test set.
Displaying popup Menu in English version by large TFT LCD, allows multi-operation modes.
(1) Rotary encoder operation
(2) Slight-touch style keyboard?
(3) Operation under PC Windows System
Save Volume reaches up to 1000 calibrated data
Calibrated data can be revised to meet due value by software, calibration report and calibrated data can get printed by software as well.
