The MI3122 SMARTEC Z Line-Loop / RCD is designed specifically for live circuit testing. The instrument contains integrated characteristics of fuses and RCD's for the evaluation of test results. The online voltage monitoring system allows the operator to control what is happening on three simultaneous voltages in real-time. The bright red and green PASS / FAIL lights and help screens for each measurement make the handling of the instrument easy and clear. All the results can be quickly saved on the instrument and then downloaded via the optional A 1291 EuroLink PRO or A 1290 EuroLink PRO Plus software for evaluation and professional report generation after testing. The MI3122 SMARTEC Z Line-Loop / RCD performs RCD, loop, line, AC voltage, frequency and phase sequence tests required by the EN 61557 standard.
Key applications include domestic and industrial live circuit testing as well as testing o fsingle phase and 3-phase, TN and TT systems.
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.
- 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 enable hands-free operation.
