The tester features a rugged industrial-grade enclosure designed to withstand a 6-inch drop without damage. It incorporates a high-speed micro-controller with precise peak-voltage detection circuitry and solid-state switching to disconnect the line exactly at the voltage peak.
All measurement channels (Line-Ground, Line-Neutral, Neutral-Ground) use high-impedance probes to avoid influencing the circuit under test. The system includes built-in scope output for waveform analysis and an ergonomic front panel with one-button operation for maximum efficiency and operator safety.
Testing Principle
The apparatus powers the equipment under test to its rated voltage, then disconnects the supply precisely at the voltage peak (positive or negative). It measures and records the residual voltage decay on accessible parts (plug pins or internal terminals) over a preset time, automatically determining compliance with the required decay limits of the selected IEC standard.
Common Error Mitigation
To ensure repeatable and accurate results, always confirm the correct polarity and standard preset before testing. Verify that test leads are securely connected and free of damage. Perform a zero-voltage check prior to each test sequence and allow the unit to stabilize after power-on. Regular calibration of the voltage measurement circuit maintains long-term accuracy.
