This PDF document is about the instruction manual of KEW 3021A・3022A・3023A Insulation Resistance Tester
This instruction manual provides operating instructions for the Kyoritsu KEW 3021A, 3022A, and 3023A digital insulation resistance testers. These instruments are designed for testing low-voltage installations below 600V and feature four resistance ranges, an audible continuity check function, and auto-discharge capabilities. The manual details safety warnings, instrument layout, preparation steps, and specific measurement procedures including voltage checks, insulation resistance, and continuity.
| Measuring range (Insulation resistance) | 0~4/40/400/2000MΩ |
|---|---|
| Accuracy | (2%rdg + 6dgt) |
| Safety standards | IEC 61010-1 (CAT II 600V) |
A maximum of 99 data points can be saved to the internal memory at the insulation resistance range.
The battery indicator mark flickers when the battery voltage drops to the lower limit.
