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
