ProInstall-75-UK Multifunction Installation Tester for fast, easy testing. With new advanced features, it is the perfect installation testing tool for verifying the safety of electrical installations in domestic, commercial and industrial applications. It ensures that fixed wiring is correctly installed and compliant with IEC 60364, HD 384 requirements and all relevant local standards including BS7671 18th Edition wiring regulations.ProInstall-75-UK is efficient to use as it allows the user to measure loop impedance without tripping RCDs, eliminating the need to bypass them. Slim reach probes allow the user to keep their eyes on the panel while probing hard-to-reach areas. With easy-to-operate controls, a large display with a wide viewing angle, padded neck strap and a compact, lightweight, ergonomic design, the tester is comfortable to use for all day testing. ProInstall-75-UK features a dual display providing simultaneous readout of mains voltage and frequency. It offers advanced loop testing which prevents RCDs from tripping and a fast high-current loop test for circuits with no RCDs. There is a PASS/FAIL indication for RCD test results and a variable RCD current mode for customised settings. It also provides an indication of phase sequence. ProInstall-75-UK is designed to measure AC voltage, insulation resistance and loop and line impedance and carry out PEFC/PSC testing and continuity testing. Voltage measurement can be selected quickly and easily between L-N, L-PE and N-PE. A Zero Adapter ensures easy, reliable and accurate test lead compensation, while an auto-null feature subtracts lead resistance from measurements, storing it in memory even after powering down.
