Tachometer Frequently Asked Questions
Question number FAQ-0922
I am using an LG-9200/TM-3130. I am measuring by attaching 25 small pieces of reflective stickers to a φ60 rotating body. I would like to know the estimated cause and solution for the following: When rotation detection is switched from ON to OFF, the TM displays for a few seconds and then (after a delay) becomes 0.
Turning off the "Auto Zero Time" setting on the TM-3130 activates the rapid deceleration tracking function.
If the input signal decreases rapidly and no input signal is received for more than approximately 1 second, this function will automatically slow down the measured value until it reaches "0" after approximately 11 seconds.
If you set the "Auto Zero Time" setting on the TM-3130 to 0.5 to 10 seconds, the measured value will become "0" if there is no signal input for the set duration. The measured value will be held for the set duration. Please check the "Auto Zero Time" setting.
