Socket & See IRC Check Insulation and Continuity Resistance Calibration Check Box

Product Details:

The Socket & See IRC Calibration Check Box is designed to provide peace of mind when performing on-site calibrations using high-quality 2% resistors. Proves continuity accuracy (0.5Ω, 1Ω, 2Ω) and proves insulation accuracy (0.5MΩ, 2MΩ, 200MΩ), with universal 4mm lead terminals which can be used in association with any standard or multifunction tester.

For those testers who include a null feature, the IRC Check Box can “null out” the test lead resistance prior to providing continuity.

The IRC Check Box is pocket-sized, sturdy, simple to use, and comes with a certificate of conformity.
