2. Built-in power supply, automatically generates three-phase high-power test power.
3. It can measure the no-load current, no-load loss, short-circuit voltage, and short-circuit loss of various types of transformers.
4. It can automatically perform 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 will automatically calculate the corrected result, which is very suitable for units that do not have conditions for short-circuit tests on slightly larger capacity transformers.
5. Wide voltage range: the maximum measurable voltage is 750V, and accuracy can be guaranteed without switching gears. It will not damage 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 liquid crystal display, full Chinese menu and operation prompts to achieve friendly human-machine dialogue, touch buttons make operation easier, wide temperature LCD with brightness adjustment, adaptable to winter and summer seasons.
7. Users can print out the test results at any time through the micro printer.
8. Test result storage function, can store 200 sets of capacity test data.

Precautions
1. During measurement, do not touch the test object.
2. If the test leads are short-circuited or the high and low voltage connections are reversed, the fuse will blow. After the fuse blows, if a measurement is attempted, the display will stop after showing "Measuring, please wait!". Please turn off the power, replace the fuse with the same capacity, and measure again.
3. Ensure good contact of connections. The instrument should be properly grounded!
4. The working place of the instrument should be far away from strong electric fields, strong magnetic fields, and high-frequency equipment. The power supply interference should be as small as possible. It is advisable to use lighting lines. If the power supply interference is still large, the instrument can be charged through an AC purified power line. The capacity of the AC purified power supply should be greater than 200VA.
5. During operation, if the LCD display is disordered, all keys have no response, or the measured value is far from the actual value, press the reset key or turn off the power and restart the operation.
