Electrical Installation Safety SINGLE-FUNCTIONAL TESTERS
MI 3122 SMARTECZ Line-Loop / RCD
The MI 3122 SMARTEC Z Line-Loop / RCD is designed specifically for live circuit testing. The instrument contains inte- grated characteristics of fuses and RCDs 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 MI 3122 SMARTEC Z Line-Loop / RCD performs RCD, loop, line, AC voltage, frequency and phase sequence tests required by the EN 61557 standard.
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 com- plete with built-in help screens for ref- erencing on site.
• LED Pass/Fail indicators: two LED in- dicators for PASS / FAIL evaluation of test results are placed on both sides of the LCD.
• Built-in fuse tables: this unique fea- ture 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 with- out tripping the RCD.
• Built-in charger & rechargeable bat- teries: instrument has a built-in charg- ing circuit and comes complete with a set of rechargeable NiMH batteries.
• RCD auto: automated RCD testing pro- cedure significantly reduces test time. • Easy to use: large bright LCD display
1. 32
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.
APPLICATION:
• Domestic and Industrial testing;
live circuit
• Testing of single phase and 3-phase, TT and TN systems.
