FASTCHECK3010G. Multifunction Installation Tester (Type G)

Test UK sockets, RCDs and loop impedance, measure TRMS voltage and harmonics, and create reports via APP. The FASTCHECK3010G is a compact multifunction electrical installation tester designed for checking compatible UK Type G socket connections and carrying out a range of electrical measurements. Its plug-in format combines socket wiring checks, TRMS voltage measurement and installation testing in one portable instrument. Designed for single-phase and bi-phase systems (120-265V), it measures AC voltage from 120 to 265V and frequency from 42 to 69Hz. Socket diagnostics help identify open earth or neutral connections, reversed conductors and contact voltage above 50V. RCD testing supports types AC, A and F, with x1/2, x1 and x5 test settings, 0° or 180° selection, AUTO mode and contact voltage measurement. Loop impedance testing covers 0.01 to 999 ohms in TT and TN systems, with standard 15mA and low-current 6mA test options. For further analysis, the instrument provides voltage harmonics and total harmonic distortion (THD%) measurements. Results can be stored in its 64-record memory and used to generate reports through the KPS FASTCHECK app for Android or iOS. A 1.77-inch TFT display with 6000 counts makes readings accessible, while mains power eliminates the need for a separate battery. Weighing 110g, the tester is rated CAT III 300V and is supplied with a carrying case and user manual. UK SOCKET AND VOLTAGE TESTING: Check wiring on compatible Type G outlets and measure AC voltage from 120 to 265V using True RMS technology. Supports single-phase and bi-phase systems (120-265V), with frequency measurement from 42 to 69Hz and indications for open earth, missing neutral and reversed connections. RCD AND LOOP IMPEDANCE TESTING: Test residual current devices of types AC, A and F using x1/2, x1 and x5 settings, 0° or 180° selection and AUTO mode. Includes trip time and contact voltage measurement, plus fault loop impedance testing from 0.01 to 999 ohms in TT and TN installations. COMPACT DISPLAY: Features a 1.77-inch TFT screen with 6000 counts, internal memory for 64 results and wireless connectivity. The KPS FASTCHECK app for Android and iOS enables report generation from saved measurements. Compact 81.5 x 70 x 83mm housing weighs 110g. CAT III 300V AND POWER ANALYSIS: Specified to IEC 61010-1, IEC 61010-2-30, IEC 61557-3, IEC 61557-6 and IEC/EN 61326-1, with a CAT III 300V rating. Provides voltage harmonic analysis and THD% measurement, alongside 15mA standard and 6mA low-current loop test options. MAINS-POWERED TESTER WITH CASE: Supplied with a carrying case and user manual, the FASTCHECK3010G draws power from the connected mains supply. Designed for electricians and installation testing professionals working with compatible UK sockets. Follow the manufacturer's instructions and applicable electrical safety procedures.
