Convert the voltage on analog channel X (specified in Task AnalogX) to a temperature based
on the built in voltage to temperature equation TP20M. This is a temperature probe used by
the Maine district of the United States Geological Survey. The actual equation is:
tp20m (AnalogX)
The Created Tasks button allows
measurement values from other Tasks as
well as the current Task to be used. The
current Task value will appear as RawValue
in the list. Note that some values may not
appear in the list and can thus cause an
ERR or erroneous value to appear when
pressing the Evaluate button. To avoid
this, verify that each Task being used in the
equation has a Value, and if not, select the
Task and press the Measure button.
