Appendix B. Changing the HC2S3 Settings
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:
B.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 Section 7.4. 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
