BRIEF INTRODUCTION
DC grounding resistance tester is used for measuring resistance between exposed conductive parts and the total ground terminal of electrical equipment.It reflects safe ground performance of ground parts .CS9950E series DC programmable grounding resistance tester is designed according to the safe standards for IEC,ISO,BS,UL,JIS and so on. With good test performance and strong test adaptive capacity,this series tester can output 30A,40A,even 60A current ,testing safe ground resistance of ground return circuit of electrical equipment,examine and weigh index of ground return circuit bearing big current,avoid life damage when insulation is damaged or insulation performance decline
| Main features |
| 1. Measure DC grounding resistance of a variety of motors, electrical appliances, instruments and meters, household appliances and otherelectrical equipment with the power grid. 2. Meet the testing requirements of IEC 61851 - Electric vehicle conductive charging system and UL1703- safety-approved standards of theflat-plate solar modules. 3. Software automatic calibration to ensure the accuracy of the test results. 4. Test file is automatically saved, and can be continuous testing. 5. External control and communication 6. Timing and pause function 7. Open alarm 8. Optional RS232, RS485 interface, the standard PLC interface |
