6.12.1.2. Control Inputs
Control inputs allow the user to remotely initiate ZERO and SPAN calibration modes are provided
through a 10-pin connector labeled CONTROL IN on the analyzer’s rear panel. These are opto-
isolated, digital inputs that are activated when a 5 VDC signal from the “U” pin is connected to the
respective input pin.
