It generates selectable high test voltages and measures insulation resistance, helping detect moisture, degradation or leakage paths before faults occur.\u003c\/p\u003e\n\u003cp\u003eThe meter combines a \u003cstrong\u003edigital display with analog-style bar\u003c\/strong\u003e, automatic ranging and safety-focused features including \u003cstrong\u003eautomatic discharge after testing\u003c\/strong\u003e. In addition to insulation measurement, it provides \u003cstrong\u003eAC\/DC voltage testing from 10–600V\u003c\/strong\u003e for quick verification of live circuits.\u003c\/p\u003e\n\u003cp\u003eData
