Amprobe SpeedTest 2018 Dual Function Loop & RCD Tester.
Speedtest 2018 is a multifunction instrument for testing of RCD's total earth resistance, line and fault impedance with calculation of prospective short circuit current and phase sequence indication, permits to check times both manually and automatically and tripping currents of any kind of RCD general and selective type A and AC, measure earth resistance directly in the socket without causing RCD tripping, effect measurement of line and/or fault loop impedance (with and without tripping of any RCD installed upstream) and calculation of prospective short circuit current.
