The installation testers C.A 6131 and C.A 6133 are intended to test the safety of electrical installations: For new installations before commissioning, for existing installations even during operation, and to locate faults. Especially for test services, the portable devices are easy to use, highly efficient and comply with the applicable standards.The operation of the C.A 6131 is easy. Each control element on the front side has only one function. Its ergonomics have been developed for simplified operation under all conditions.The C.A 6131 can be used to measure the voltage, resistance, resistance and insulation of loops. The current can be measured using an external clamp. Fault current circuit breakers of type A & AC can be tested in ramp or pulse mode. The C.A 6131 also shows the direction of the rotating field. The test result (OK/not i.O) is immediately displayed on the device.This text is machine translated.
