HT Instruments MACROTEST G3 Multifunction Tester Testing Electrical Installation

MACROTEST G3 is an innovative instrument capable of carrying out safety tests on civil and industrial electric systems in compliance with IEC/EN61557-1. Its capacitive TFT color touch-screen display, its icon menu, its help-on-line and its user-friendly development make the instrument extremely intuitive even for unskilled users. Its numberless features grant the user a wide range of applications in the world of measurements.
MACROTEST G3 allows saving all measures into an internal memory so transferring the saved data to a PC, a PDA or a smartphone by means of USB (provided as standard) or Wi-Fi (C2013 optional accessory) interfaces. The software supplied among standard accessories allows printing testing reports.
MACROTESTG3 also drives the optional accessory IMP57 to carry out high resolution (0.1m) loop/line impedance measurements with prospective short-circuit current calculation. This allows accurate measurements even close to power stations enabling the user to correctly size the protection devices in any system.
Further possible tests consist in checking breakdown current, tripping current, I2t relative to breakers (MCB) with curves B, C, D, K and fuses type gG as well as aM. Through optional clamp model HT96U it is possible to measure the leakage current. Optional clamp T2100 permits to quickly check the resistance of earth probes without disconnection from earth system.
