Commands
:SOURce:TCouple:DEFine
Function
Sets a user-defined thermocouple.
Syntax
:SOURce:TCouple:DEFine <
String
>
<String>: Definition of the relationship between
the temperature range and thermoelectromotive
force.
For details on string syntax, see appendix 4.
Example
:SOURCE:TCOUPLE:
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
thermoelectromotive force of the user-defined
thermocouple, execute the commands in the
following table.
:SOURCE:TCOUPLE:WRITE
Writes the user definitions to the 2553A’s
internal memory. The user definitions take
effect.
:SOURCE:FUNCTION TCOUPLE
Sets the source function to TCouple.
:SOURCE:TYPE USER
Sets the type to USER.
:OUTPUT ON
Finally, when you turn the output on, the
2553A sources the thermoelectromotive
force of the user-defined thermocouple.
:SOURce:TCouple:DELete
Function
Deletes user-defined thermocouples.
Syntax
:SOURce:TCouple:DELete
Example
:SOURCE:TCOUPLE:DELETE
Description This command deletes all user definitions created
with the :SOURce:TCouple:DEFine command. To
create a new user definition, delete existing user
definitions with this command.
:SOURce:TCouple:SETTing?
Function
Queries all temperature range settings that are
user-defined for the thermocouple.
Syntax
:SOURce:TCouple:SETTing?
Example
:SOURCE:TCOUPLE:SETTING?
-> "...;100.0,200.0,1.0E+5,-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.
:SOURce:TCouple:TYPE
Function
Sets or queries the type string for distinguishing
user-defined thermocouples.
Syntax
:SOURce:TCouple:TYPE <
String
>
:SOURce:TCouple:TYPE?
<String>: No character or a single ASCII code
character in the range of 20 to 7E (hexadecimal)
For the characters that correspond to ASCII
codes 20 to 7E, see appendix 7.
Example
:SOURCE:TCOUPLE:TYPE "k"
:SOURCE:TCOUPLE:TYPE?
-> :SOURCE:TCOUPLE:TYPE "k"
Description If set to “No character,” the two characters “°” and
“C” will be displayed in the dot matrix LEDs of the
2553A front panel.
If set to a single character, “°C” will be displayed
in the first character of the dot matrix LEDs and
the specified character in the second.
If the unit is set to °F on a model with the -UF
suffix code, F is displayed in place of C. You can
change the temperature unit from the 2553A front
panel (see section 6.6). You can also use the
:SYSTem:UNIT command.
:SOURce:TCouple:WRITe
Function
Writes a user-defined thermocouple.
Syntax
:SOURce:TCouple:WRITe
Example
:SOURCE:TCOUPLE:WRITE
Description The user definition set with the
:SOURce:TCouple:DEFine command is written to
the 2553A’s internal memory.
:SOURce:TYPE
Function
Sets or queries the thermocouple or RTD type.
Syntax
:SOURce:TYPE {R|S|B|J|T|E|K|N|C|A|
PT100|USER}
Example
:SOURCE:TYPE B
:SOURCE:TYPE? -> :SOURCE:TYPE B
Description Before setting the type, use the
:SOURce:FUNCtion command to set the source
function to TCouple or RTD. If the source function
is VOLTage, CURRent, RESistance, or RJTemp
and you set the type, a “221: Setting conflict”
error will occur. “NONE” is returned as a response
to a query.
