HCU2 operation
When the system is used in conjunction with an HCU2 hand control unit, the probe damp and probe reset buttons on the HCU2 are active.
The probe reset button will pulse the PPOFF PICS line when pressed, but only while the system is in manual mode. The probe damp button
will toggle the PDAMP PICS line when pressed, but only while the system is in manual mode. Both the probe reset and probe damp buttons
on the HCU2 can be made inactive by use of a switch on the rear panel of the PHC10-3.
