Chapter 3 Probes
Using a Probe Rack
Use a probe rack to store additional probe tips. Probe tips housed in the probe
rack can be exchanged during inspections according to need. For example, a
probe rack allows the user to switch from a single probe tip to a star probe tip.
All probe transitions must occur through the appropriate established methods.
You must never manually change a probe tip or manually place/remove probes
from ports in the rack. Valid probe transitions can be set in the Probe Library
dialog box by selecting the probe you wish to switch to, then select the "Set
Current" button. Proper probe transitions can also be included in a program.
If at any time, either during normal operation or while a program is executing,
the QC-5000 fails to correctly perform a probe change, then the affected probes
will need to be unloaded from the probe rack, then reloaded.
Probe Rack Setup
Set machine zero each time you launch the QC-5000. A repeatable machine
zero position is required to find the probe rack.
Follow the instructions of the probe rack manufacturer to install the probe rack
on your system. Once the probe rack is mounted and it's position entered in
the QC-5000 it cannot be moved.
NOTE
Mount the probe rack so the current probe can reach each of
the ports.
NOTE
Mount the rack firmly so there is no movement in any direction.
