Multiple measurements

To increase measuring certainty, the TNC can run each probing
process up to three times in sequence. Define the number
of measurements in machine parameter ProbeSettings >
Configuration of probe behavior > Automatic mode: Multiple
measurements with probe function. If the measured position
values differ too greatly, the TNC outputs an error message
(the limit value is defined in Confidence interval of multiple
measurements). With multiple measurement it is possible to
detect random errors, e.g. from contamination.
If the measured values lie within the confidence interval, the TNC
saves the mean value of the measured positions.

Confidence interval of multiple measurements

When you perform a multiple measurement, you store the
value that the measured values may vary in ProbeSettings >
Configuration of probe behavior > Automatic mode: Confidence
interval of multiple measurements. If the difference in the
measured values exceeds the value defined by you, the TNC
outputs an error message.
