DCB-4 Daily Check Box Electrical Safety Comprehensive Calibrator Self Check Box Resistance Box For Safety Tester
The daily check box is for research and development of Ground Resistance, Insulation Resistance, Withstand Voltage and Leakage Current in electrical safety test. It can meet the needs of daily check. It is especially convenient to check electrical safety tester. And it has two check points (pass/fail) each test item in order to meet different needs and determine whether the safety tester can work normally.
