Technical Indicators
1. Input Characteristics
Active part:
Voltage measurement range: 0~10V
Current measurement range: 0~10A
Passive part:
Voltage measurement range: 0~750V wide range.
Current measurement range: 0~100A, all internal ranges automatically switched.
2. Accuracy
Voltage, current, frequency: ±0.2%
Power: ±0.5% (CosΦ>0.1), ±1.0% (0.02<CosΦ<0.1)
3. Operating temperature: -10℃~ +40℃
4. Charging power supply: AC 160V~260V
5. Insulation: (1) Insulation resistance between voltage/current input terminals and the case ≥100M?.
(2) The working power input terminal withstands 2KV (RMS) power frequency against the case for 1 minute test.
6. Dimensions: 32cm×24cm×13cm

Functional Features
1. Can measure the capacity of various distribution transformers, passive measurement, convenient and accurate.
2. Built-in power supply, automatically generates three-phase high-power test power.
3. Can measure no-load current, no-load loss, short-circuit voltage, and short-circuit loss of various types of transformers.
4. Automatically performs waveform distortion correction, temperature correction, voltage correction, and current correction (short-circuit test under non-rated current conditions). The operator only needs to input the correction index according to the transformer type, and the instrument automatically calculates the corrected results, which is very suitable for units that do not have conditions for short-circuit tests on slightly larger capacity transformers.
5. Wide voltage range: maximum voltage measurement up to 750V, ensuring accuracy without switching gears. It will not damage the instrument due to incorrect voltage gear selection.
6. Battery remaining percentage indication function, not just a simple low battery alarm.
7. Large screen, high brightness LCD display, full Chinese menu and operation prompts for friendly human-machine dialogue, touch buttons for easier operation, wide temperature LCD with brightness adjustment, adaptable to winter and summer seasons.
8. Users can print out test data at any time through the micro printer.
9. Test result storage function, can store 200 sets of capacity test data.
