Code 6x: Analog Outputs Check
The x in the code represents the analog output number (1 through 3).
1. Press the [6] key, followed by an analog output number (1 through 3).
The system should respond by placing the analog output number (1 through 3) in the
center display, and the analog output abbreviation
AnAl
in the main display.
The analog output is normally proportional to pressure. The 146 unit sends a square
wave to make the output go back and forth between 0 and 10 Volts. An output detection
device must be used to detect if the analog output is indeed fluctuating between 0 and 10
Volts.
