Product description

2.  Reset switch

Automatically, the probe will reset to the armed state when the PI 7-2 is powered 
up.  Occasionally, it may be necessary to perform a manual reset, for example after 
changing the probe stylus.

Press the RESET button on the front panel for 2 seconds to reset the probe to the 
armed (seated) state.

CAUTION:  Pressing the RESET button inhibits probe triggers.  Before pressing 
the button, the CMM must be stationary, in manual mode, with the stylus clear 
of the workpiece.

NOTE:  The action of unlocking and locking the PH10 series motorised head will 
perform the same function as the RESET button.
