Connector probe
Inside each probe connector is a specific trim resistor. Cutting off the connector without
replacing this resistor will cause wrong measuring results. DO NOT FORGET to connect
the resistor again if you have to replace the connector and/or keep the original plug in
case of contacting 2D support.
