5.5 Temperature Scale
Temperature inputs may be set in either Fahrenheit or Celsius
degrees. The default temperature scale is Fahrenheit. To change to
Celsius:
1. Press SENSOR ON/OFF.
2. Press TEMP. The Model 1108 responds:“Off,” indicating
Celsius scale has replaced Fahrenheit scale.
3. To return to Fahrenheit scale, repeat the key sequence. The
Model 1108 responds:“On,” indicating Fahrenheit scale is in
effect. NOTE
When switching from Fahrenheit to Celsius, or vice
versa, the change applies to all inputs configured to
read temperature. When switching temperature scales
it is important to reset high and low temperature lim-
its on all temperature inputs. Refer to Section 5.4.1 to
reset temperature limits.
5.6 Temperature Calibration
To compensate for minor variances in sensor accuracy, an offset
may be programmed for each temperature input. The amount of
offset is measured in degrees Fahrenheit or degrees Celsius.
Adjustments are possible within a range from -10 degrees to +10
degrees. For example, if input 3 is sensing temperature and is
reading 1 degree too high, then the calibration for input 3 is set at
-1 to obtain an accurate reading.
