Callendar-Van Dusen (CVD), or IPTS-68 is selected as the type of coefficients
to calculate or from the Thermistor Probe Coefficients dialog.
Enabled and disabled
The Calculate button is not enabled until the required data is entered and the
scales are selected.
Dialog information
The user must select the Reference Scale and UUT Scale and enter Reference
Temperatures and UUT Resistances.
The choices for the reference scale are °C, °F, or K. The choices for the UUT
scale are Ohms or KOhms.
The reference temperatures are the temperature readings taken from the refer-
ence probe at the nominal temperatures. The UUT resistances are the readings
taken from the test probes at the nominal temperatures.
The yellow boxes designate the values that must be filled in for the type of co-
efficients being calculated to produce an exact solution. Entering values into
the white boxes is optional and produces an overdetermined solution. Section
