Mode of Application - MMode #91
Description
Based on the datasheet for the M90E26, there are four mode the metering IC could be set in.
There is a mode that helps the meter know when tampering is taking place by comparing the current running through the live wire to the current running through the neutral wire and if the difference is bigger that the threshold that has been configured in the registers of the metering IC, the meter will detect this.
In anti tampering mode,metering is done on the Live line and the Neutral line and the difference is calculated and compared with the threshold.
There is little information about the mode being used and the possibility of this in the OpenMeter.
