Abstract
A touch trigger probe has electrical contacts. A comparator compares the resistance of the contacts with a threshold, in order to generate a repeatable trigger signal when the contacts open. To ensure that the trigger signal can be generated reliably even if the resistance of the contacts when closed should increase, the threshold set is variable. The threshold can, for example, be set by a sample and hold circuit which tracks the resistance of the contacts when closed.
