Megger Residual Current Device Testers RCDT320. Residual Current Device Testers. Megger RCD Tester The Megger RCD tester is a residual current device tester with 1000mA test current. This tester covers a wider supply voltage range of 50 V to 280 V, allowing use with centre-tapped 110 V supplies. It incorporates ramp testing, for RCD tripping current measurement, and the unique auto sequence test feature, which saves time by allowing the tester to conduct all the RCD tests, and to store the results while the operator stands by the RCD, resetting it as appropriate. It has an extended operating current range to cover 10 mA to 1,000 mA devices, and the ability to measure AC supply voltage and frequency is added. The large liquid crystal display for test results is backlit in this model, making it easier to use in locations with low ambient light levels.
