4.10 Procedure for detecting the culmination point
The TESA-Hite 400 / 700 has an automatic system for determining the shape of the surface being
probed (concave or convex). Hence, it is not necessary to indicate to the TESA-Hite 400 / 700,
whether the surface being probed is flat, a bore or a shaft, as it can independently detect whether
there is a culminating point and, according to whether it is an upward or a downward probe, whether
it is a maximum or a minimum. In short, just probe normally and release the key if the surface is flat
or wait about 1 second in the probing zone to see whether the probe is in contact with a bore or a
shaft and whether the diameter is to be measured. The system automatically switches to culminating-
point detection mode. Then just move the part or the TESA-Hite 400 / 700 so that the probe passes
through the culmination point.
Once the symbol
or
appears on the display, the system will have automatically detected the
maximum or minimum point of the bore or shaft to be measured. At this point, the measuring key can
be released.
