Question number FAQ-0902

I'm using an HT-4200 to measure rotational speed, but the measured value is approximately twice the specified rotational speed. Could you please tell me how to resolve this?

Please check the current pulse count setting on the HT-4200.
If there is one reflective sheet attached to the rotating body, it needs to be set to 1P/R.

<Operation>
Pressing the "MEMORY / COND" switch on the HT-4200 unit for more than 2 seconds will enter the reflective sheet setting mode.
Then the current number of spins will be displayed in the MAIN display section.
In this state, press the "MEMORY / COND" switch. Each press will increment the set number of sheets, so set the current number of reflective sheets you have applied.
