The MI 3125BT EurotestCOMBO performs all the necessary tests for installation safety testing on TT and TN systems.
MEASURING FUNCTIONS
• Insulation resistance with DC voltage
• Continuity of PE conductors with 200 mA test current with polarity change
• Continuity of PE conductors with 7 mA test current (continuous measurement) without RCD tripping
• Line impedance
• Loop impedance
• Loop impedance with Trip Lock RCD function
• TRMS voltage and frequency
• Phase sequence
• RCD testing (general and selective, type AC, A and B)
• Earth resistance (3-wire method)
KEY FEATURES
• LED Pass/Fail indicators: two LED indicators for PASS / FAIL evaluation of test results are placed on both sides of the LCD
• Help screens: instrument comes complete with built-in help screens for referencing on site
• Earth resistance measurement: instrument performs 3-wire earth resistance testing with two additional rods
• 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
• Upgradeable: if changes occur to the regulations, upgrades can be made to the firmware to keep the instrument up to date
• Polarity swap: automatic polarity reversal on continuity test
• Insulation range: wide range of insulation test voltages from 50 V to 1000 V, reading up to 1000 MΩ
• Multi-system testing: tests on single and multiphase TT and TN systems
• RCD auto: automated RCD testing procedure significantly reduces test time
• B type RCD testing is supported
• BT connectivity
• PC SW Eurolink PRO
