default is Range 4. The choices for high range are Range 6 through Range
11, or None. The default is Range 8.

• If the type selected is Polynomial, the order of the polynomial is required.

The order is selectable from 3rd to 9th order. The default for platinum
probes is 4th order. The number of coefficients calculated is one more
than the order of the polynomial (i.e. for a 4th order polynomial, 5 coeffi-
cients are calculated). The minimum number of set-points needed must
exceed the order by 1 or more.

• If the type selected is IPTS-68 or Callendar-Van Dusen, additional infor-

mation is not required.

The Continue button displays the Raw Data dialog for the selected type of
coefficients.

The Cancel button returns to the TableWare main display.

3.2.2

Thermistor probe

The Thermistor Probe Coefficients dialog (Figure 10) is displayed when the
Continue button is selected from the Probe Information dialog and the coeffi-
cients being calculated are for a thermistor probe.

Enabled and disabled

All options are enabled at all times.

Dialog information

The only type of coefficients that can be calculated for thermistor probes is
polynomial. Both T(R) and R(T) polynomial coefficients are calculated.
