Auto testing (RCDT320/330)

Where the RCD under test and tester need to be in different locations, the user connects the RCDT320/330 to the circuit and goes to standby the RCD under test to reset it. The RCDT320/330 will automatically perform a 1/2I, I and 5I test at both  0° and 180°. The RCD is reset each time it trips by the electrician and the tester proceeds to the next test automatically. All results are displayed at the end of the test, saving you time and energy.

The RCDT330 additionally offers the facility to save test results to internal memory. Over 1000 results can be saved on site, and downloaded to a computer when convenient. Data is stored in a non-volatile memory, being retained when the instrument is switched off or batteries are exhausted.
