What Are Logic Inputs Used For?

Our digital panel meters have several logic input ports which you can use to trigger certain actions. For example you can programme a logic input to Tare your display. Or to reset it. Or to freeze the display. Or to blank it. Or to show the peak or valley value. Or to show a 2nd scaled value for metric/imperial applications. Or to toggle between net and gross. Or to trigger a print output data transmission.
