43760 or ASTM E1137 sensors, the coefficients for R0, ALPHA, DELTA, and BETA
are 100.0, 0.00385055, 1.499786, and 0.10863 respectively.
Some probes may be provided with A, B, and C coefficients for the Callendar-Van
Dusen equation in the following form:
r t
( [
The A, B, and C coefficients can be converted to Alpha, Beta and Delta coefficients
using the following equation:
α =
TYPE (Res)
The Res (Resistance) option displays the resistance, in ohms, of the selected reference
probe.

Figure 15 PROBE TEST menu

The Test (PROBE TEST) menu is used to test the parameters for a given probe. To
test the parameters of the selected probe, input a test resistance and read the calculated
temperature for that resistance.
SELECT
The SELECT parameter is the probe number of the probe to be tested.
