:USLope <n>
[:SENSe[1]]:TEMPerature:DTCouple:USLope <n> Set TC slope
<n> = -0.99999 to 0.99999 Specify TC slope
DEFault Set TC slope to 20E-6
MINimum Set TC slope to -0.99999
MAXimum Set TC slope to 0.99999
:USLope? Query TC slope
:USLope? DEFault Query *RST default slope value
:USLope? MINimum Query minimum slope value
:USLope? MAXimum Query maximum slope value
When the USER type thermocouple is selected (see previous command), this command is used
to set the slope (coefficient) for the thermocouple or thermopile that you are using.
Refer to the Model 1801 Nanovolt Preamp Instruction manual for details on making differential
thermocouple temperature measurements.
PRINT #1, "output 16; :temp:dtc:usl 10E-6; usl?" ' Set TC slope
PRINT #1, "enter 16" ' Get response from 2002
:RTEMperature <n>
[:SENSe[1]]:TEMPerature:DTCouple:RTEMperature <n> Specify reference TC temperature
<n> = -273 to 2000 Specify reference TC temperature in °C
DEFault Reference TC 0°C
MINimum Reference TC temperature -273°C
MAXimum Reference TC temperature 2000°C
:RTEMperature? Query reference TC temperature
:RTEMperature? DEFault Query *RST default temperature
:RTEMperature? MINimum Query minimum temperature
:RTEMperature? MAXimum Query maximum temperature
When one of the seven standard thermocouples (J, K, T, E, R, S or B) is selected (see :TYPE
command), this command is used to enter the reference temperature at which the reference ther-
mocouple will be operated during measurement.
Refer to the Model 1801 Nanovolt Preamp Instruction manual for details on making differential
thermocouple temperature measurements.
PRINT #1, "output 16; :temp:dtc:rtem 100; rtem?" ' Specify reference temp
PRINT #1, "enter 16" ' Get response from 2002
:SENSe2 subsystem
This subsystem is used to read the digital I/O port.
:TTL[1]:DATA?
:SENSe2:TTL[1]:DATA? Read input port
This command is used to read the single line of the digital input port. A value of “1” indicates
that the input port is high (ON), and a value of “0” indicates that the port is low (OFF).
PRINT #1, "output 16; :sens2:ttl:data?" ' Read input port
PRINT #1, "enter 16" ' Get response from 2002
