The Metrel MI 3136 EurotestCOMBO XC is a multifunction installation tester. It tests and inspects low-voltage electrical installations in domestic, commercial, and industrial environments. It supports testing of TT and TN systems, EVSE installations, earthing systems, fire safety checks, and maintenance applications.
The tester has a 4.3-inch high-resolution touchscreen, automated test routines (Auto TT, Auto TT RCD, Auto TN, and Auto TN RCD), and an RCD AUTO function.
Built-in Wi-Fi and Bluetooth connectivity enable wireless synchronisation with Metrel Cloud and compatibility with the Metrel ES Manager software for reporting, data storage, and test structure management.
Additional functions include real-time voltage monitoring across L-N, L-PE, and N-PE; automatic polarity reversal during continuity testing; built-in fuse tables for loop impedance evaluation; filtering by selected area groups; and integrated help screens for on-site guidance.
* Available with MESM PRO and Metrel Cloud licences.
