High fineness stepper motor is used to control the process of voltage regulator and carry out voltage withstand test automatically. After the start of the test, the instrument automatically closes and automatically increases the voltage according to the national standard. When the preset voltage is reached, the timing starts, the test voltage is maintained, and the voltage is automatically reduced. After reaching zero, the power is automatically cut off, indicating the end of the test, and the leakage current of each test product is displayed.

1. The instrument can test 8 insulating boots or gloves at the same time, and measure the leakage current of each test product.
2. The insulating shoe test adopts the dry test method of placing small steel balls inside, which gets rid of the traditional practice of filling the shoes with water to do the test, and it is not easy to dry after the test.
3. The measured voltage and measured current are compared in real time with high and low voltage to ensure the accuracy of the measured voltage and current value.
4. High and low voltage separation, leakage current using anti-interference wireless transmission technology to transmit back to the control box, greater protection of personal safety.
5. Each test has a breaking mechanism, when one of them breaks down or exceeds the set leakage current value, the test will automatically leave the test, does not affect other tests.
