1. สินค้าหมดview
The HT Instruments MACROTESTG3 is an advanced multifunction installation tester designed for safety tests on civil and industrial electrical systems, adhering to IEC/EN61557-1 standards. It features a resistive TFT color touch-screen display, an intuitive icon menu, and integrated help-on-line for ease of use. The device supports a wide range of measurements and includes internal memory for data storage, with transfer capabilities via USB or built-in Wi-Fi to iOS and Android devices.
The MACROTESTG3 can perform high-resolution loop/line impedance measurements with prospective short-circuit current calculations using the optional IMP57 accessory. It also checks breakdown current, tripping current, and I2t for MCBs (B, C, D, K curves) and fuses (gG, aM types), along with percentagอีโวลtage drop on main power lines. RCD tests up to 10A are possible with the optional RCDX10 accessory. Leakage current can be measured using the optional HT96U clamp, and earth probe resistance can be checked with the optional T2100 clamp โดยไม่ขาดการเชื่อมต่อ
