HT Instruments MACROTEST Gx Series

HT Instruments MACROTEST Gx Series

The HT Instruments MACROTEST Gx Series is an innovative multifunction installation tester capable of carrying out safety tests on civil and industrial electric systems in compliance with IEC/EN61557-1. Its resistive 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.

The multifunction installation tester MACROTEST Gx Series allows saving all measures into an internal memory so transferring the saved data to a PC by means of USB (provided as standard) or built in Wi-Fi interfaces with an iOS and Android smartphones or tablets .The software supplied among standard accessories allows printing testing reports.The multifunction installation tester MACROTESTG1 has as Optional clamp T2100 permits to quickly check the resistance of earth probes without disconnection from earth 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 and the percentage voltage drop on the main power lines. The test on earth leakage relay tester RCDs up to 10A (with optional accessory RCDX10) is also possible with the instrument. Through optional clamp model HT96U it is possible to measure the leakage current. The multifunction installation tester MACROTESTG3 has as Optional clamp T2100 permits to quickly check the resistance of earth probes without disconnection from earth system.
