Programming example 10 OUTPUT 716; “:temp:rtd:rzer 200; rzer?”
20 ENTER 716; A$
30 PRINT A$
40 END
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).

Description 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
