Introduction
This document describes how a shunt current sensor can be used with the STPM01 metering device in single-phase metering applications without tamper detection.

Special considerations must be taken into account when the shunt is designed:
■ The current density must be kept constant
■ The power dissipation must be reduced, as it can influence the ambient temperature
   within the meter housing. In the event of large current overloads, this can become an
   explosion hazard.
