The three-phase electrical parameter tester is suitable for true RMS detection of parameters such as three-phase voltage, current, power, power factor, and frequency in industries including motors, water pumps, transformers, and power systems. It can be wired according to either a three-phase three-wire system or a three-phase four-wire system, and can also be used as a single-phase meter. The accuracy is 0.5 class and 0.2 class.
I. Measurement Range and Accuracy of the Tester:
Measurement Parameter | Measurement Range | Measurement Error | Resolution | Overload Capacity |
Voltage | (10.0～500.0) V | ±(0.25% reading + 0.25% range) | 0.1V | 600V |
Current | (0.030～40.00) A | <10A 0.001A | 50A | |
Active Power | Depending on voltage and current range | Power factor = 1.0: | <1000W 0.1W | |
Power Factor | 0.20～1.00 | ±0.02 | 0.01 | |
Frequency | (45～65) Hz | ±0.2 Hz | 0.1Hz |
II. Operating Conditions
1. Temperature conditions for ensuring measurement accuracy: 20℃ ±5℃.
2. Operating temperature range: 0～40℃, relative air humidity: 30%～90%.
3. Indoor environment free of corrosive and explosive gases.
4. Power supply: AC220V/50Hz.
5. Fuse: 0.5A.
III. Instrument Safety Indicators
