It has functions such as memory, calculation, hold, self-check, and leakage alarm. It features high-voltage short-circuit protection, overcurrent protection, and high-voltage presetting. The high-voltage self-discharge time is less than 5 seconds. Test results are displayed on two 3 1/2 LCD digital displays, one showing voltage value and the other showing current value, with high accuracy and good reliability. It can be used as an adjustable DC high-voltage source (1kV～10kV) with output current ≤1mA.
