• If the source function is TCouple, RTD,
RJTemp and you set the range, a “221: Setting
conflict” error will occur. 9.91E+37 is returned
as a response to a query.
• If you change the range, the output turns off.
:SOURce:RJC?
Function
Queries all reference junction compensation
settings.
Syntax
:SOURce:RJC?
:SOURce:RJC:MODE
Function
Sets or queries the reference junction
compensation mode.
Syntax
:SOURce:RJC:MODE {AUTO|INTernal|
MANual}
AUTO: Auto
INTernal: Internal
MANual: Manual input
Example
:SOURCE:RJC:MODE INTERNAL
:SOURCE:RJC:MODE?
-> :SOURCE:RJC:MODE INTERNAL
Description The 2553A corrects the sourced
thermoelectromotive force (RJC) according to the
set mode.
• AUTO
If an external RJ sensor is detected, a
correction is performed using the measured
temperature of the external RJ sensor.
Otherwise, a correction is performed using
the temperature of the 2553A output terminals
(internal).
• INTernal
A correction is performed using the temperature
of the 2553A output terminals (internal).
• MANual
A correction is performed using a manually
input temperature. You can set the temperature
from the 2553A front panel (see section
6.5 and chapter 4). You can also set it with
the :SOURce:RJC:TEMPerature:MANual
command. If you do not want to apply
correction, set the temperature to 0°C.
:SOURce:RJC:STATe?
Function
Queries the reference junction compensation
operating state.
Syntax
:SOURce:RJC:STATe?
-> {EXTernal|INTernal|MANual|OFF}
EXTernal: External
INTernal: Internal
MANual: Manual input
OFF: When manual input is selected and the
reference junction temperature is set to
0°C.
Example
:SOURCE:RJC:STATE?
-> :SOURCE:RJC:STATE EXTERNAL
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 reference junction compensation (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.
