Profile:

Used for conducting insulation strength tests on various electrical products, electrical components, insulation materials, etc. at specified voltages to assess the insulation level of the products, discover insulation defects in the tested products, and measure the ability to withstand overvoltage.

Features:

1. 320 × 240 LCD display, high-speed thermal printer.
2. Four measurement methods for high voltage, high voltage current, low voltage, and low voltage current, high-precision sensors, and high-performance 14 bit AD acquisition chips.
3. Human computer dialogue full keyboard operation mode, intelligent working process, optional automatic and manual modes.
4. Real time display of high voltage, high current, low voltage, low current, time, and withstand voltage results, with intuitive and clear display.
5. Complete overvoltage and overcurrent protection, capable of setting output voltage, high voltage current upper limit, low voltage current upper limit, and timing time.
6. It has a zero return detection function, and the test can only be conducted after the zero return is confirmed, which is safe and reliable.
7. During automatic testing, it is possible to pause the voltage rise or fall at multiple points, making it easier to observe the condition of the test sample during the test.
8. It has insulation resistance testing function, which directly reflects the insulation strength of the tested object.
9. Approaching voltage regulation algorithm, automatically timing the withstand voltage after reaching the set voltage, and automatically reducing the voltage to zero after the timing ends.
10. When the set high or low voltage current is exceeded, the voltage output will be automatically cut off, the voltage will drop back to zero, and an audible and visual alarm will occur.
