Calibration Interval
User specific intervals should be
established based upon frequency of use,
handling practices and measuring
environment.
Effects of Temperature
If measurements will be made in extreme
hot or cold temperatures, measure your
Calibration Standards in the working
environment. The 6000 should then be
optimized in that same environment.
How to Optimize
One- or Two-point Optimization should be
performed if readings are not falling within
the expected range of thickness for the
application being measured.
One-point Optimization
Simple Zero Adjustment
(F, FS, FRS, N, NS, NRS, FN, FNS, FNRS, SPFS and
NAS probes only)
Measure your uncoated part. If the Gage
does not read “
0 0” within the tolerance of
the probe being used, lift the probe from
the surface and adjust the display down 8
8
or up 9 9 until the display reads “0
0”.
Measure and adjust until the average of a
series of readings on the uncoated
surface is “
0 0” (within tolerance).
Average Zero Adjustment
(Main Menu)
On rough or curved surfaces the Simple
Zero Adjustment method must be
repeated several times to get a good “
0 0”.
A preferred method is to take several
readings on the uncoated part and
average the result.
