Programmable Leakage Current Tester is designed to perform the Leakage Current Tests of electronic devices, electrical appliances, switchboards, insulating materials, cables, meters and lighting devices. Suitable for type tests and routine tests.
Features:
- AC / DC high voltage, insulation resistance, grounding resistance, leakage current, low start and power test can be done with a single key.
- With DSS (Digital Signal Synthesis) technology, it produces a correct, stable, clean and low distortion sine wave signal.
- The power is shown on the display while the leakage current test is being performed.
- Adjustable high voltage rise and fall time is adapted to the requirements of different test samples.
- Two different ARC sensing: current and step.
- Test results can be synchronized to save and support detailed and complete statistics
- Frequency range: 50Hz / 60Hz
- OSC
- Supports a maximum of 12 characters for file name input.
- New, Delete and Jump shortcuts for both file and test step.
- Supports high-capacity storage: 50 files x 40 steps, 25 files x 80 steps.
- Keyboard lock prevents changing the parameter set.
- Supports RS232 / RS485, PLC, GPIB, USB interface, optional scan code gun.
