Tachometer Frequently Asked Questions

The HT-3100 digital hand tachometer has a "Lo/Hi measurement range selector switch".

Please note that if you are using the KS-200 peripheral speed ring, the decimal point position cannot be automatically adjusted, so please read the displayed value by dividing it by 10. (Think of it as the value divided by 10 in your head.)

(Example) If the display shows "123", the actual speed should be read as "12.3 m/min".
If the display shows "523", the actual speed should be read as "52.3 m/min".
If the display shows "12.3", the actual speed should be read as "1.23 m/min".
