| Message: | CR-ER01 Digital Earth Tester CR-ER01 Digital Earth Tester is digital precision earth resistance tester for electrical contractors, utility test engineers and earth test specialists. It is handheld, small size, rugged design, and easy-to-use. Key Features 2-pole measurement does not require the auxiliary ground stake; it is easy-to-use. Measure earth resistance and soil resistivity by 3-pole and 4-pole measurementsMeasure AC voltage.To test resistance on-service and off-serviceClearly read and record data Removing wire resistance while 2-pole and 3-pole, ensure accurate measurements.
