Calibration groups (G1, G2, G3...G18)
All calibration values shown on the screen are simultaneously applied
when the ENTER key is pressed. While this is acceptable in most
cases, some applications require entering a series of calibrations at
different times. The example shown here illustrates this difference.
Calibrating two points on a rod.
Calibrating offset surfaces Master G1.
Calibrating offset surfaces Master G2.
When measuring runout at two points on a
rod, both channels are measuring a
common surface and can be calibrated
simultaneously. In this example, both
channels are calibrated to zero on the rod
surface in calibration group 1 (G1).
Completed calibrations are indicated by
filled circles at the right of the actual channel
values.
When measuring the low and high lifts of
two offset cams, simultaneous calibration
on the offset surfaces is not possible. First
one channel must be calibrated to zero on
the low surface of one cam, then after
turning the cam shaft 90 degrees, the
second channel must be calibrated to zero
on the low surface of the second cam.
The first calibration is performed in
calibration group 1 (G1), then the camshaft
is turned 90 degrees, and the second
calibration is performed in calibration group
2 (G2). By performing the calibrations in
different groups, the calibrations are made
independent. Completed calibrations are
indicated by filled circles at the right of the
actual channel values.
