- Wide measuring range and precise voltage rating: Measures insulation resistance up to 2000 MΩ at 1000 V with accuracy of ±(4% of reading+2 digits). This enables testing of both high and moderate insulation levels with a single instrument. - Large, backlit display for easy reading: 90 x 48 mm LCD with backlight, capable of displaying values up to 1999 for clear results in dim or challenging lighting conditions. - Convenience features for daily use: Data hold function to freeze the reading for documentation or later recording, and auto power off to conserve battery when the meter is idle. - Clear over range indication: If the measured value exceeds the maximum range, the display shows 1 to indicate an out-of-range condition. - Practical use scenarios • Industrial maintenance and repair: Check insulation resistance of cables, motors, transformers, and switchgear to ensure insulation integrity before operation or after service. • Equipment commissioning and QA: Verify insulation resistance during installation and testing of new electrical equipment to confirm compliance with specifications. • Home and facility safety checks: Assess insulation of power cords, appliances, and other electrical devices to identify potential insulation failures and reduce safety risks.
