Commands
:SOURce:RJC:TEMPerature:EXTernal?
Function
Queries the external reference junction
temperature.
Syntax
:SOURCE:RJC:TEMPerature:EXTernal?
Example
:SOURCE:RJC:TEMPERATURE:EXTernal?
-> :SOURCE:RJC:TEMPERATURE:
EXTERNAL 0.0
Description If the reference junction temperature is outside
the measurement range, 9.9E+37 or –9.9E+37 is
returned.
:SOURce:RJC:TEMPerature:INTernal?
Function
Queries the 2553A’s internal reference junction
(2553A output terminal) temperature.
Syntax
:SOURCE:RJC:TEMPerature:INTernal?
Example
:SOURCE:RJC:TEMPERATURE:INTernal?
-> :SOURCE:RJC:TEMPERATURE:
INTERNAL 0.0
Description If the reference junction temperature is outside
the measurement range, 9.9E+37 or –9.9E+37 is
returned.
:SOURce:RJC:TEMPerature:MANual
Function
Sets or queries the temperature for when the
reference junction compensation mode is set to
manual input.
Syntax
:SOURCE:RJC:TEMPerature:
MANual <
Temperature
>
:SOURCE:RJC:TEMPerature:MANual?
Example
:SOURCE:RJC:TEMPERATURE:MANUAl 0.0
:SOURCE:RJC:TEMPERATURE:MANUAl?
-> :SOURCE:RJC:TEMPERATURE:MANUAL 0.0
:SOURce:RJC:RESister?
Function
Queries the resistance of the RJ sensor to be
used for the external reference junction for 0°C.
Syntax
:SOURCE:RJC:RESister?
Example
:SOURCE:RJC:RESISTER?
-> :SOURCE:RJC:RESISTER 100.00
:SOURce:RTD?
Function
Queries all user-defined RTD settings.
Syntax
:SOURce:RTD?
:SOURce:RTD:DEFine
Function
Sets a user-defined RTD.
Syntax
:SOURce:RTD:DEFine <
String
>
<String>: Definition of the relationship between
the temperature range and resistance.
For details on string syntax, see appendix 4.
Example
:SOURCE:RTD:
DEFINE "-100.0,0.0,100.0,1.0"
Description • You can create a user definition for a single
temperature range. To set multiple temperature
ranges, repeat this command.
• After creating user definitions for the required
temperature ranges, to source the resistance of
the user-defined RTD, execute the commands
in the following table.
:SOURCE:RTD:WRITE
Writes the user definitions to the 2553A’s
internal memory. The user definitions take
effect.
:SOURCE:FUNCTION RTD
Sets the source function to RTD.
:SOURCE:TYPE USER
Sets the type to USER.
:OUTPUT ON
Finally, when you turn the output on, the
2553A sources the resistance of the user-
defined RTD.
:SOURce:RTD:DELete
Function
Deletes user-defined RTDs.
Syntax
:SOURce:RTD:DELete
Example
:SOURCE:RTD:DELETE
Description This command deletes all user definitions created
with the :SOURce:RTD:DEFine command. To
create a new user definition, delete existing user
definitions with this command.
:SOURce:RTD:SETTing?
Function
Queries all temperature range settings that are
user-defined for the RTD.
Syntax
:SOURce:RTD:SETTing?
Example
:SOURCE:RTD:SETTING?
-> "...;100.0,200.0,100.00,-1.0E+3;
..."
Description All the temperature range settings that have been
user-defined are returned in a single character
string with each setting delimited by a semicolon.
For details on string syntax, see appendix 4.
