RF Current Sensor

The RF Current Sensor is a diagnostic aid only and isn't required for a Plasma to be sustained.
The current sensor outputs the Work Coil current and the value can be seen in the RF Generator
Test. If there is a problem with the Plasma lighting it will not be as a result of the current sensor.
