7. AC load: 0-1000VA
Accuracy: 0.5%±0.05VA
Power Supply: 8、AC220V±10%，50Hz
9. Environment: -10℃ to 50℃
Humidity: ≤90% Features 1. Single unit tests CVT and electromagnetic PT error without resonant booster, standard PT, load box or calibrator. Greatly reduces field calibration workload.
2. Wide range: 6kV-800kV electromagnetic PT.
3. Built-in 0.01 class standard PT. Tests LV error by differential method. VFD for excitation curve. Accuracy to 0.05 class. During testing, generates no more than 3kV test voltage, ensuring on-site safety.
4. Simple wiring and operation with guided prompts for efficient CT/PT calibration.
5. Smart external wiring detection, prompts connection errors, ratio and polarity errors.
6. Automatically rounds test data and determines out-of-tolerance conditions. Out-of-tolerance data is highlighted in reverse color for intuitive and clear assessment of transformer data characteristics.
7. Large-capacity storage can save up to 10,000 field test data records.
8. Aluminum profile chassis with excellent anti-interference performance, ensuring operator and equipment safety during on-site high-voltage testing.
9. The instrument features a high-resolution large 8-inch true color LCD display, clearly visible under outdoor strong light, with touch screen assisted operation, simple and fast.
