:TYPE? Query RTD type
Short-form format: :temp:rtd:type?
Response message: PT100, D100, F100, PT385, PT3916, USER or SPRTD
This command is used to select the RTD standard and other related factors. When PT100, D100,
F100, PT385 or PT3916 is selected, the instrument defaults to the following RTD factors:
Type Standard
PT100 ITS-90
D100 ITS-90
F100 ITS-90
PT385 IPTS-68
PT3916 IPTS-68
Changing alpha (see :ALPHa), beta (see :BETA), delta (see :DELTa) or  at 0°C (see :RZERo)
automatically changes the type to USER . Therefore, once you program the appropriate factors
for your RTD, you can later recall that setup by using the :TYPE USER command.
With the SPRTD type selected, refer to
for standard platinum resistance thermometers.
10 OUTPUT 716; ":temp:rtd:type pt385; type?"
20 ENTER 716; A$
30 PRINT A$
40 END
Line 10 Two commands in this program message; the first programs the RTD factors to the
PT385 defaults, and the second queries the Type.
Line 20 Addresses the Model 2001 to talk.
Line 30 Displays Type (PT385).
:ALPHa <NRf>
[:SENSe[1]]:TEMPerature:RTD:ALPHa <NRf>Specify Alpha value
<NRf> = 0 to 0.01
