Line 10 Two commands in this program message; the first changes the resistance value to 200, and
the second queries the resistance value.
Line 20 Addresses the Model 2001 to talk.
Line 30 Displays the resistance value (200).

These commands program the various parameters for SPRTD (Standard Platinum Resistance Thermom-
eters). A single SPRTD, however, usually cannot be used to cover the entire range, so the temperature
range is broken up into several subranges. An SPRTD is supplied with a certificate of calibration that lists
the calibration constants and the temperature range supported. In most cases, the supplied coefficients
Set A4 coefficient
Set B4 coefficient
Set A7 coefficient
Set B7 coefficient
Set C7 coefficient
