You must know four things prior to setting the display’s span value:
1.You must know the maximum signal level for the specific transducer connected to the channel to be spanned (5 VDC, 10VDC or 20mA).
2.You must know the maximum value to be displayed when the maximum signal level for the transducer is connected to the channel to be spanned.
3.You must insure that the channel’s multiplier is set to 1.0000.
4.You must know the channel’s ‘Span Value’. That is, the value that would NOW be displayed (prior to any adjustment) if the maximum signal was fed into the input of the channel to be adjusted.
1 and 2. If this information is not on the transducer itself, consult the manufacturer of the transducer. Their literature or other documentation should specify the maximum output signal from the transducer and the maximum value to be displayed at that signal level.
