Why is the counter value incorrect on my Mitutoyo Cash Counter?

  sethprestonJul 26, 2025
  If the Mitutoyo Cash Counter displays an incorrect counter value, it might be due to several reasons. First, the parameters might not be correctly set for the type of Linear Gage. Another potential cause is that Peak mode (MAX or MIN is lit) is active; if so, cancel Peak mode. Also, check if the HOLD signal (UNIT is blinking) is being input via the external input. Finally, verify that calculation with a constant function is not active; if it is, cancel it by setting parameter number 41 to 0.

  If you cannot establish RS-232C communication with your Mitutoyo Cash Counter, verify the RS-232C connecting cable is properly connected. Ensure that RS-232C mode is active by setting parameter number 24 to 0. Check the command or HOLD trigger setting (parameter number 28) to ensure it is appropriate. Finally, confirm that the communication conditions are set correctly.
