:BETA <NRf>
[:SENSe[1]]:TEMPerature:RTD:BETA <NRf> Specify Beta value
<NRf> = 0 to 1 Specify RTD Beta value
:BETA? Query the Beta value
This command is used to check and/or change the Beta value. Keep in mind that changing the
current Beta value changes the Type to USER (see :RTD:TYPE).
PRINT #1, "output 16; temp:rtd:beta .11; beta?" ' Specify beta value
PRINT #1, "enter 16" ' Get response from 2002
:DELTa <NRf>
[:SENSe[1]]:TEMPerature:RTD:DELTa <NRf> Specify Delta value
<NRf> = 0 to 5 Specify RTD Delta value
:DELTa? Query the Delta value
This command is used to check and/or change the Delta value. Keep in mind that changing the
current Delta value changes the Type to USER (see :RTD:TYPE).
PRINT #1, "output 16; temp:rtd:delt 1.75; delt?" ' Specify delta value
PRINT #1, "enter 16" ' Get response from 2002
:RZERo <NRf>
[:SENSe[1]]:TEMPerature:RTD:RZERo <NRf> Specify resistance at 0°C
<NRf> = 0 to 10000 Specify RTD Resistance at 0°C (in ohms)
:RZERo? Query RTD resistance at 0°C
This command is used to check and/or change the Resistance at 0°C. Keep in mind that chang-
ing the current resistance value changes the Type to USER (see :RTD:TYPE).
PRINT #1, "output 16; temp:rtd:rzer 200; rzer?" ' Specify RZero value
PRINT #1, "enter 16" ' Get response from 2002
