Voltage tester MI 3122 SMARTEC Z

RCDphase sequenceAC

The MI 3122 SMARTEC Z Line-Loop / RCD is designed specifically for live circuit testing. MEASURING FUNCTIONS • Line impedance • Loop impedance • Loop impedance with Trip Lock RCD function • TRMS voltage and frequency • Phase sequence • RCD testing (general and selective, type AC and A) KEY FEATURES • Help screens: instrument comes complete with built-in help screens for referencing on site • LED Pass/Fail indicators: two LED indicators for PASS / FAIL evaluation of test results are placed on both sides of the LCD • Built-in fuse tables: this unique feature allows automatic evaluation of the line / loop impedance compared to the regulations • Online voltage monitoring: monitors all 3 voltages in real-time • Downloadable: downloads via RS232 or USB cable directly to the PC with the help of the optional software • Upgradeable: if changes occur to the regulations upgrades can be made to the firmware to keep the instrument up to date • Trip Lock function: Zs (RCD) function performs a loop impedance test without tripping the RCD • Built-in charger & rechargeable batteries: instrument has a built-in charging circuit and comes complete with a set of rechargeable NiMH batteries • RCD auto: automated RCD testing procedure significantly reduces test time • Easy to use: large bright LCD display and large buttons enable easy handling of the instrument (even while wearing gloves) • Magnetic holder: magnet for fixing instrument on metal surfaces enables hands-free operation
