Product Introduction
Using a turns ratio bridge to measure the turns ratio of a transformer involves cumbersome procedures and a narrow measurement range, which no longer meets the demands of modern fast-paced and high-efficiency measurement. To address this, our factory has developed a new generation of fully automatic turns ratio group tester using modern electronic technology. It features small size, light weight, high accuracy, and good stability. It adopts a large-screen LCD with Chinese character display, menu operation, and clear interface. The turns ratio and group can be measured in one go. This instrument is an ideal testing device for the power industry.
Precautions
1. Do not touch the test object during measurement.
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 power off, replace the fuse with one of the same rating, and retest.
3. Ensure good contact in the connections. The instrument should be properly grounded!
4. The working place of the instrument should be far 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 circuits. If power interference is still significant, the instrument can be charged via an AC power purification line. A purification power supply with a capacity greater than 200VA is sufficient.
5. During operation, if the LCD display becomes disordered, all buttons are unresponsive, or the measured values differ greatly from actual values, press the reset button or turn off the power, then 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. When working in dark places, the backlight can be turned on. To reduce display power consumption, the backlight is not very bright.
8. The instrument should be stored in a dry and ventilated place.
