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
