| How to Use Digital Insulation Resistance Meters – Basic Course
This video explains how to use a digital insulation resistance tester to measure a distribution panel. Â |
|
 |
Comparator function provides PASS/ FAIL decisions at a glance
Compare measured values to pre-set reference values to generate a pass or fail judgment with the Comparator function. The insulation testers give you pass/ fail results using a beeping sound, LCD light, and indication right on the test lead with remote control switch (option), letting you check for insulation integrity without needing to look at the instrument. Â |
 |
Robust, damage-resistant design
These instruments feature a robust design that can withstand being dropped onto concrete from a height of 1 m. Â |
 |
White LED lighting thatâs easy to read in dim locations in the field
The scale is lit by a white LED, ensuring that insulation resistance values are easy to read, even when using the instrument in a dim location. Â |
 |
Measurement switch designed for outstanding ease of use
The instrumentâs measurement switch can be operated with just the thumb. Â |
| 200 mA grounding line continuity check function
The Insulation testers can perform EV and HEV continuity checks as well as resistance measurement of safety conductors in building electrical equipment as defined by IEC 60364. Â |
