Product Features

Equipped with 320×240 LCD display and high-speed thermal printer.
Four measurement channels: high voltage, high-voltage leakage current, low voltage and low-current. Adopts high-precision sensors and high-performance 14-bit AD acquisition chip.
Full keyboard human-machine interaction. Fully intelligent test workflow, supporting automatic and manual operation modes.
Real-time display of high voltage, high-voltage leakage current, low voltage, low current, test duration and withstand voltage results with clear visualization.
Comprehensive overvoltage and overcurrent protection. Users can preset output voltage limit, upper threshold of high voltage current, upper threshold of low voltage current and timing duration.
Zero-return detection function. Tests can only start after zero calibration for enhanced safety and reliability.
Supports insulation resistance measurement to directly reflect the insulation strength of test samples.
Adopts proximity voltage regulation algorithm. Automatically starts withstand voltage timing after reaching set voltage and reduces voltage to zero upon test completion.
Automatically cuts off voltage output, drops voltage to zero and triggers audible & visual alarm once high or low current exceeds preset limits.
Optimized hardware and software anti-interference design with multiple shielding methods, suitable for harsh electromagnetic environments.
