Set up a tachometer in Balance


By default, the analyzer is setup for CSI 404 tachometers.

Pseudo Tach must be disabled for the Balance program. When the pseudo tach is disabled, a standard 1x tach is produced.

Note: The CSI 404A and 404B tachometers require power ON if directly connected to the analyzer. If you connect your tachometer to the 404P external tach power supply, set the power to OFF.


  1. From the Balance main menu, press F3 Job Setup > F10 Tach Config > F6 Tach Setup.
    The Tachometer Setup screen appears.
  2. Set the following options as necessary.
    Option Description
    F2 Pseudo Tach Disable for the Balance program. When the Pseudo Tach is disabled, a standard 1x tach is produced.
    F5 Tach Power Enable the analyzer to power the tachometer. The default is to provide power to the tachometer.
    F7 Set Trigger Edge

    Set the trigger to occur on the rising edge or falling edge of a waveform. The default is Falling Edge.

    F8 Set Trigger Level Enter the value between -100 and 100 required to start a tachometer pulse. For Level measurement, set the input that is the source of the trigger. The default is 2.0 Volts.
    F9 Set Edge Delay Enter the number of seconds between 0 and 16 that occurs between each tachometer pulse. This helps prevent double triggering. The default is 0.0 seconds.
    F10 Show RPM F10 Hide RPM View or hide the last RPM the tachometer read and the time between each reading. A last time value of 0 indicates the tachometer is continuously reading the RPM.
    F12 Set Defaults Restore the default values for all tachometer setup options on the screen.
