:RTD commands
See paragraph 2.4.5 for detailed information on making temperature measurements.
:TYPE <name>
[:SENSe[1]]:TEMPerature:RTD:TYPE <name> Set RTD parameters
<name> = PT100 Selects default parameters for the PT100 type (ITS-90)
D100 Selects default parameters for the D100 type (ITS-90)
F100 Selects default parameters for the F100 type (ITS-90)
PT385 Selects default parameters for the PT385 type (ITS-68)
PT3916 Selects default parameters for the PT3916 type (ITS-68)
USER Selects user-defined parameters
SPRTD Selects SPRTD type
:TYPE? Query RTD type
This command is used to select the RTD standard and the other related factors. When one of the
parameters other than USER is selected, the instrument defaults to the following RTD factors:
RZero
Standard Type Alpha Beta Delta
Ω
at 0°C
ITS-90 PT100 0.003850 0.10863 1.49990 100
Ω
ITS-90 D100 0.003920 0.10630 1.49710 100
Ω
ITS-90 F100 0.003900 0.11000 1.49589 100
Ω
IPTS-68 PT385 0.003850 0.11100 1.50700 100
Ω
IPTS-68 PT3916 0.003916 0.11600 1.50594 100
Ω
Changing Alpha (see :ALPHa), Beta (see :BETA), Delta (see :DELTa) or
Ω
at 0°C (see
:RZERo) automatically changes the Type to USER (:TYPE USER). Thus, once you program
the appropriate factors for your RTD, you can later recall that setup by using the :TYPE USER
command.
PRINT #1, "output 16; temp:rtd:type pt385; type?" ' Select standard
PRINT #1, "enter 16" ' Get response from 2002
:ALPHa <NRf>
[:SENSe[1]]:TEMPerature:RTD:ALPHa <NRf> Specify Alpha value
<NRf> = 0 to 0.01 Specify RTD Alpha value
:ALPHa? Query the Alpha value
This command is used to check and/or change the Alpha value. Keep in mind that changing the
current Alpha value changes the Type to USER (see :RTD:TYPE).
PRINT #1, "output 16; temp:rtd:alpha .0035; alph?" ' Specify alpha value
PRINT #1, "enter 16" ' Get response from 2002
