1. In the middle of the measurement, the ratio tester does not touch the test sample.
2. If the test line is short-circuited and the high and low voltages are reversed, the fuse will be blown. After the fuse is blown, if the measurement is made, stop it after the message "Please wait!" is displayed. Please shut down, replace the same amount of insurance, and retest.
3. The connection should be well protected. The instrument should be well grounded!
4. The workplace of the instrument should be kept away from strong electric fields, strong magnetic fields, and high-frequency equipment. The power supply interference is as small as possible, and the lighting line should be selected. If the power supply interferes with the product album (4 sheets) is still large, it can be charged by the AC purification power cord instrument. AC purification power supply capacity is greater than 200VA.
5. When the instrument is working, if there is a liquid crystal display disorder, there is no response by pressing any key, or the measured value is far from the actual value. Press the reset key, or turn off the power and operate again.
6. If the display has no characters or the color is very light, adjust the brightness potentiometer to a suitable position.
7. The transformer ratio tester works in a dark place and can turn on the backlight. In order to reduce the power consumption of the display, the backlight is not very bright.
8. The instrument should be stored in a dry and ventilated place.
