Choose Insulation Testers (5KV) Calibration when accuracy matters on site. We keep your high voltage insulation results precise and repeatable. First, we check your instrument condition and leads. Then we clean old labels and fit fresh identification. Also, we replace cells if needed for reliable testing.
Next, we verify output test voltages at 500 V, 1 kV, 2.5 kV and 5 kV. We confirm short-circuit current sits within the maker limits. We also confirm guard terminal performance and leakage behaviour. Therefore your readings stay stable under real-world loads. We step resistance points across the full range, including very high values. Moreover, we check reading linearity near pass and fail thresholds. We then verify PI and DAR calculations for trend analysis. Finally, we review timer, ramp, and hold functions where fitted.
You receive a clear certificate with measurement points and results. We include unique asset IDs for your compliance records. We also include service notes and next due dates. Because we use UKAS-calibrated standards, your results remain fully traceable. This approach supports audits and quality systems with confidence.
