What is the attitude of distribution company when Optosense has already been installed on the electricity meter?

The customer can not interfere with an electricity meter. On the other hand, sticking the sensor is not considered interfering with an electricity meter. An inexperienced employee of a distribution company may disconnect the sensor for the purposes of inspection of the electricity meter or his reading, but he can not confiscate it nor destroy it. The output from the electricity meter is intended for an end user’s purposes, and the data serves for its inspection.
