We are currently using the MIH with a full configuration star cluster in two
positions, 0°,0° and 0°,180°.

We are having troubles keeping the probes in calibration. My operators are
telling me that they see more problems on the shifts that they are shifting
the positions continuously between themselves.

Unfortunately, it only takes a shift of .001" in the probe 3 X position to
throw the measurements using probes 2&4 out of whack.

Any thoughts?

Thanks!!
