A control circuit is disposed in the housing, electrically coupled to the at least one electrical connector and configured to control the graphical display. The control circuit may be further configured to be coupled to an external sensor, such as a current sensor. The control circuit may be configured to perform an electrical measurement and to display a result of the measurement on the graphical display. |
