Features
1. Can accurately 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 based on 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. No damage to the instrument due to incorrect gear selection.
6. Battery remaining capacity percentage indication function, not just a simple low battery alarm.
6. Large screen, high-brightness LCD display, full Chinese menu and operation prompts for friendly human-machine interaction, touch buttons for easier operation, wide-temperature LCD with brightness adjustment, adaptable to winter and summer seasons.
7. Users can print test results at any time through the micro printer.
8. Test result storage function, can store 200 sets of capacity test data.

Instructions
Since the instrument has a built-in high-capacity lithium battery, to extend the battery life, if the instrument is not used for a long time, it is recommended to discharge it once every two months and then fully charge it.
No display after power on: Turn off the power first, check if the fuse is blown, and replace the fuse if necessary.
Sudden black screen: Press the reset button to restart the measurement.
Incorrect measurement and calculation results: Check external wiring, whether operating according to the manual, whether there is poor contact or wrong wiring; check if related parameter settings are incorrect.
The no-load test results fluctuate significantly; please note that the test power supply should be separated from the power supply used by high-power impact equipment such as workshop cranes.
