On general and selective (time delayed) & programmed RCDs with ratings of 10 mA, 30 mA, 100 mA, 300 mA, 500 mA, and 1000 mA, the Megger RCDT330 tester can conduct 1/2I, 1xI, and 5xI tests. You can have an RCD tester for every situation if you combine this with the ability to download via USB up to 1000 test results using the included download manager software! The data on the RCDT330 is kept in non-volatile memory, so it is preserved even when the device is turned off or its batteries run out. Selecting a job reference number (up to 256) makes it possible to test several sites with the RCDT330 and to obtain the results separately. As a "Fuel Gauge," a memory bar graph displays the amount of memory that has been
