The Major Tech K4140 has everything you need for earth loop impedance tests and PSC testing  incorporating anti-trip technology (ATT) which bypasses RCDs electronically when performing loop impedance tests. This saves time and money by not having to take the RCD out of the circuit when testing and is a safer procedure to follow. With the ATT function enabled, a test current of 15 mA or less is applied between line and earth. It enables resolution loop impedance measurements (up to 0,1 Ω), without tripping RCDs rated at 30 mA and above. Other features include a convenient lock down test button for hands-free testing with auto start operation. The display and front panel keyboard is back lit for visibility in poor light. The K4140 features a dual display allowing simultaneous measurements such as loop and PFC/PSC, testing of phase rotation, voltage and frequency.
