The MI 3102 BT model is a multifunctional measuring device that performs all necessary measurements in low-voltage electrical installations in accordance with the PN-EN 61557 standard. This device has an implemented AUTO SEQUENCE mode, which allows you to automate measurements in TN, TT and IT networks (ISFL, IMD). In addition, the MI 3102 BT EurotestXE device allows you to monitor the mains voltage in real mode, check the correctness of the phase sequence, measure the earth resistance, illuminance and current (TRMS value). The meter has implemented overcurrent protection characteristics and an RCD residual current device, which allows for immediate evaluation of the measurement result (Positive/Negative). All results can be easily stored in memory and then copied to a PC using the Metrel Electrical Safety Manager software (included as standard!) for processing and reporting.
