4.19.19 :RTD commands
:TYPE <name>
[:SENSe[1]]:TEMPerature:RTD:TYPE <name> Set RTD parameters
Parameters <name> = PT100 Selects default parameters for the PT100 standard
= D100 Selects default parameters for the D100 standard
= F100 Selects default parameters for the F100 standard
= PT385 Selects default parameters for the PT385 standard
= PT3916 Selects default parameters for the PT3916 standard
= USER Selects user-defined parameters
= SPRTD Selects the SPRTD type.
Format :temp:rtd:type <name>
Defaults Power-up Saved power-on setup
*RST PT100
:SYSTem:PRESet PT100
Query :TYPE? Query RTD type
Short-form format: :temp:rtd:type?
Response message: PT100, D100, F100, PT385, PT3916, USER or SPRTD
Description 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 Alpha Beta Delta Ω at 0°C
PT100 ITS-90 0.003850 0.10863 1.49990 100Ω
D100 ITS-90 0.003920 0.10630 1.49710 100Ω
F100 ITS-90 0.003900 0.11000 1.49589 100Ω
PT385 IPTS-68 0.003850 0.11100 1.50700 100Ω
PT3916 IPTS-68 0.003916 0.11600 1.50594 100Ω
Changing alpha (see :ALPHa), beta (see :BETA), delta (see :DELTa) or Ω 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 paragraph 4.19.20 to program the various parameters for
standard platinum resistance thermometers.
Programming example 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
Parameter <NRf> = 0 to 0.01 Specify RTD Alpha value
Format :temp:rtd:alph <NRf>
