The UNI-T UT582 Digital RCD (ELCB) Tester makes every RCD testing job easy. With six trip current settings, it has the capacity to test a range of systems operating at different power levels. The RCD tester has a trip time resolution of 1ms, providing highly precise readings suitable for professionals. Accuracy is maintained throughout all measurement ranges; a maximum error of +/-0.6%+4 is offered in all results, making it suitable for professional usage.
Using a digital current tester can be tricky, which is why the UNI-T UT582 Digital RCD (ELCB) Tester operates with a sophisticated buzzer system. This provides audible notification when mis-operation occurs. It also provides signals on power-off and disconnection. In the situation of an overload, a relevant visual notification will appear on the screen of the device.
The simple user interface of the RCD tester allows all testing jobs to be carried out at speed. Three buttons and a rotational switch is all that is needed for system navigation. A wide digital display provides instant feedback to the user. Three input ports provide a means for connecting to electrical circuits.
