Preventing multiple probe hits
Probe hit delay is the minimum quiet time between valid probe hits. Probe hit
delay eliminates the possibility of unintended multiple probe measurements
due to probe vibration against a surface or, mechanical switch noise. The de-
fault of 0.10 seconds of delay is adequate for most applications. Increase the
delay in 0.10 second increments if multiple probe hits occur.
Enter the probe hit delay into the Probe
hit delay field.
Specifying probe re-qualification across sessions
A lack of encoder reference marks, temperature variations, different operators
and other measurement conditions might make it necessary to re-qualify the
reference position of a touch probe before each new measurement session.
NOTE
It is only necessary to re-qualify the reference position of
indexable probes.
Check the Require requalification... box
to require requalification before each new
session.
Adding requalification to the features list
Check the Create a feature... box to in-
clude probe re-qualifications in the fea-
tures list.
Specifying maximum form error for qualification
Form error is the difference between a nominal dimension and the measured
value of the dimension. The maximum form error allowed for probe calibration
should be set slightly higher than the machine repeatability specified by the
system provider or installer. For example, if machine repeatability is found to be
3 microns, the form error might reasonably be set to 5 microns.
Enter the maximum allowable qualifi-
cation form error into the Maximum
form for... field.
Specifying indexable probe type
The QC5000 supports indexable probes
listed in the Indexable probes type group.
Click the radio button of the desired
indexable probe. Click the None radio
button if the desired probe is not
indexable.
