Description If the reference junction compensation (RJC)
mode is set to AUTO and an external RJ sensor
is detected, EXTernal is returned. If an external
RJ sensor is not detected, INTernal is returned.
If the RJC mode is set to INTernal, INTernal is
returned.
If the RJC mode is set to MANual and the
manually input reference junction temperature is
not 0°C, MANual is returned. If the temperature is
set to 0°C, OFF is returned.
:SOURce:RJC:TEMPerature?
Function
Queries the reference junction compensation
temperature.
Syntax
:SOURCE:RJC:TEMPerature?
Example
:SOURCE:RJC:TEMPERATURE?
-> :SOURCE:RJC:TEMPERATURE:MANUAL 0.0
Description The manual-input reference junction temperature
is returned.
:SOURce:RJC:TEMPerature:AUTO
Function
Sets or queries the reference junction
compensation temperature.
Syntax
:SOURCE:RJC:TEMPerature:AUTO
<
Temperature
>
:SOURCE:RJC:TEMPerature:AUTO?
Example
:SOURCE:RJC:TEMPERATURE:AUTO 0.0
:SOURCE:RJC:TEMPERATURE:AUTO?
-> :SOURCE:RJC:TEMPERATURE:AUTO 0.0
Description • If the RJC mode is set to MANual, you can set
the reference junction temperature. You can
also query the value.
If the RJC mode is set to AUTO or INTernal,
you cannot set the reference junction
temperature. A “221: Setting conflict” error will
occur. You can query the reference junction
temperature.
• If the reference junction temperature is outside
the measurement range, 9.9E+37 or –9.9E+37
is returned in response to a query.
: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 2560A’s internal reference junction
(2560A low voltage-current 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 6.
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 2560A’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
:STATE
ON
Finally, when you turn the output on, the
2560A sources the resistance of the user-
defined RTD.
