Note that any changes to the scaling/calibration factors submitted at the end of this Wizard
will reset the date of calibration for that probe. Editing other portions of the Wizard will not
update the calibration date.
If you are setting up the probe for the first time, we recommend that you first test the probe
operation: click on Summary, review your inputs, and click on Submit. This will bring up the
Probe Configuration page, click on Probe Status at the top of the page and view the probe
reading. Run it through tests if desired to ensure it is working/reading as expected. If all is
well, go on to configure an alarm, relay, or notification.
3.6. Non-Linear Scaling
The example provided below in Figure 13 shows the relationship between a temperature
sensor that outputs a logarithmic scale compared with a simple Fahrenheit temperature scale.
Each line that connects the two scales shows the relationship between them and how it
changes over the temperature range.
For each point on the Analog input sensor scale, a corresponding value must be entered into
the output side. The graph in Figure 13 shows the input Analog scale on the X-axis and the
output Temperature scale on the Y-axis. The data entry can be achieved by simply clicking on
each point on the graph to draw the curve. As the mouse cursor hovers over a data point, both
the Analog and Output scaled values are displayed. Each point in the graph is displayed with
a hollow circle and can be edited with a right-click mouse action. This menu allows Edit
mAmp Value or Edit Output Value. The Get Current Value selection loads the current raw
value from the sensor and updates the selected data point. This is useful if the scaling curve
