Click on “Device Manager”, select “Analog Outputs” to see the following
screen:
Change the lower and upper range values and click “OK”. The following
screen shows the range –60 to +30:
D.4 Multiplier and Offsets for Temperature Range
Analog Output 2 is 0 to 1V (1000 mV) for the temperature range. If the range
has been changed from the default (–40 to +60), then the multiplier and offset
for the measurement instruction will have to be changed from those shown for
the program examples in Appendix B ,
Example Programs
(p. B-1)
. For example,
for a range of –60 to 30, the multiplier to convert the measurement result (mV)
to temperature, is the full scale range of temperature divided by the full scale
range of mV, and the Offset is -60.0 as shown below:
Multiplier = mV * (90°C/1000 mV)
= 0.09
Offset = –60.0
