January 2009 UDA2182 Universal Dual Analyzer Product Manual 75
NOTE 1.
The entries for any parameter are in the units of that parameter.
For example:
Parameters in engineering units.
Input 1 PV
Input 1 Temp
Input 2 PV
Input 2 Temp
Pharma Out 1
Pharma Out 2
Parameters in %
Control 1
Control 2
Math 1,2,3,4
Output 1,2,3
So in the SETUP OUTPUT menu, for the SOURCE and Hi Range and Low Range
values, these look at the units of that source.
If retransmitting a pH input, the Hi Range and Low Range values would normally be set
to 14 pH and 0 pH. (14 pH= 100% output, and 0 pH = 0% output.)
But if the output is to go to a valve, to open the valve or operate a pump through a range
of 0-100% open, and has a SOURCE of CONTROL 1, then the units of the
CONTROL 1 output is in units of %, so in the SETUP OUTPUT menu, the High Range
and Low Range would be in % units.
