Operation of the ThreadChecker

Wire colors & pin-out.
The wire colors and typical connection diagram are as follows.

Teach sequence
Before the system is first used it must have the ‘teach’ sequence run. In order to do
this you must have a representative threaded and non-threaded hole. The system can
be easily calibrated to any new sensor designed for the ThreadChecker as well as for
most hole/thread configurations with a simple calibration sequence.

1. Connect the sensor and power source to the electronics. Allow the system to

warm up for a minimum of 5 minutes.

2. With the sensor in ‘air’ (i.e. not in a hole or near any conductive material), press

and hold the ‘Teach’ button until the Thread LED blinks fast then release (more
than 1 second but less than 10 seconds), the Thread LED should blink slowly.

3. Position the sensor tip in the threaded hole and momentarily press the ‘Teach’

button. The Status LED will blink fast.

4. Position the sensor in an unthreaded or bad hole and momentarily press the

‘Teach’ button. The LED should be solid red indicating no threads present. The
system is now calibrated and ready for use.

Since the switch point is half way between these 2 points you can teach these in
reverse order (bad then good) if desired.
