Working Principle of Transformer Ratio Bridge Tester Usage 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 show "Measuring, please wait!" and then stop. Please power off, replace the fuse with one of the same capacity, and retest.
3. Ensure good contact in connections, and the instrument should be properly grounded!
4. The working place of the instrument should be away from strong electric fields, strong magnetic fields, and high-frequency equipment. The less interference in the power supply, the better. It is advisable to use lighting circuits. If power supply interference is still significant, an AC purified power supply with a capacity greater than 200VA can be used to power the instrument.
5. If the LCD display is disordered, all keys are unresponsive, or the measured values differ greatly from actual values during operation, press the reset button or turn off the power and restart the operation.
6. If the display shows no characters or the characters are too faint, adjust the brightness potentiometer to a suitable position.
7. The instrument should be stored in a dry and ventilated place.
Technical Performance
