The Ground Resistance Checker (Cat. #5000.74) provides a quick andsimple way to check the measurement accuracy of your ground resistancetester. The unit provides test resistances for:■ RE (25.0 or 5.0Ω, depending on switch position) with ±2%accuracy■ RH (100.0Ω) with ±3% accuracy■ RS (100.0Ω) with ±3% accuracyTo use the Ground Resistance Checker:1. Connect the Ground Resistance Checker to the instrument. Theleads are color-coded; match each lead’s color to the appropriateinstrument terminal color. (If required by your instrument’s terminals,use the four fork terminals supplied with the Ground ResistanceChecker.)2. Turn the Ground Resistance Checker’s switch to the left (25.0Ω).3. If you are testing a Model 6400 series instrument, turn the dial to asetting that displays RE, RH, and RS. For some instruments this is the4 Pole setting, for others (e.g. the Model 6472) this is 3+1 Pole.The Ground Resistance Checker (Cat. #5000.74) provides a quick andsimple way to check the measurement accuracy of your ground resistancetester.
