8. Remove the two Posidriv screws that secure the spring retainer holder to the
probe body; then remove the small black plastic holder.
9. Lift the circuit board, transformer, and cable out of the probe body as a unit.
If you need to, you can unplug the transformer from the circuit board.
10. To reassemble the probe, reverse the procedure above.
When replacing the slide switch, spring retainer, and transformer top as a
unit, push the slide switch contacts gently inside the sides of the bottom
housing.
To make repairs inside the probe body, disassemble the probe as described in the
previous section. If you need to solder on the circuit board, use a minimum of
heat, and observe normal circuit board procedures.
If you need to replace the current transformer, replace the entire assembly
including the other half of the transformer core mounted in the slide switch. The
transformer halves are matched at the factory before shipment.
Repairing the termination can consist of replacing either the connectors or the
circuit board. These tasks are described below.
