Frequently Asked Questions about the Tachometer

Question number FAQ-0902

I am using the HT-4200 to measure the rotation speed, but the actual measured value is about twice the specified rotation speed. I would like to know how to resolve this issue.

Please check the number of pulses currently set on the HT-4200.
If there is one reflective sheet attached to the rotating body, it needs to be set to 1P/R.

＜Operation＞
Press and hold the “MEMORY / COND” switch on the HT-4200 unit for 2 seconds or more to enter reflective sheet setting mode.
The currently set number of sheets will then be displayed in the MAIN display.
In this state, each time you press the “MEMORY / COND” switch, the set number of sheets will increase by one. Set the number of reflective sheets currently attached.
