Description

Kyoritsu 3125a The KYORITSU KEW 3125A High Voltage Insulation Tester is a robust handheld instrument designed for evaluating the insulation integrity of electrical equipment by applying DC test voltages up to 5000 V. It enables maintenance personnel to verify insulation resistance up to the terohm range (up to 1 TΩ on the highest range), making it suitable for heavy-duty diagnostics on cables, switchgear, transformers, motors, and other high-voltage components. The instrument integrates safety features and ergonomic design to support field operations under varied conditions. The tester offers multiple voltage ranges (250 V, 500 V, 1000 V, 2500 V, and for the 3125A an additional 5000 V range), with autoranging insulation measurement up to 1 TΩ. It incorporates auto-discharge to safely bleed off capacitive charge post-test, a voltage monitor to confirm discharge, and diagnostic functions including Polarization Index (PI) and Dielectric Absorption Ratio (DAR) measurements for deeper insulation condition assessment. A bar graph and digital display with backlight enhance readability, while live-circuit warning (audible/visible) prevents inadvertent testing on energized circuits. Auto-power-off conserves battery life during inactivity Ergonomically arranged controls and protective fingerguards facilitate safe handling. The instrument meets IEC safety standards (IEC 61010-1/2-030, CAT IV 300 V/CAT III 600 V) and includes guard terminal support to suppress surface leakage in cable te
