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.

The

 switch point is 

set 

half way between these 2 points

. The

 teach 

process can 

also be performed in 

reverse order (bad then good) if desired.
