:SOURce:RTD:TYPE
Function
Sets or queries the type string for distinguishing
user-defined RTDs.
Syntax
:SOURce:RTD:TYPE <
String
>
:SOURce:RTD: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:RTD:TYPE "p"
:SOURCE:RTD:TYPE?
-> :SOURCE:RTD:TYPE "p"
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:RTD:WRITe
Function
Writes a user-defined RTD.
Syntax
:SOURce:RTD:WRITe
Example
:SOURCE:RTD:WRITE
Description The user definition set with the
:SOURce:RTD:DEFine command is written to the
2553A’s internal memory.
:SOURce:SLEVel
Function
Sets or queries the output setting with polarity
information.
Syntax
:SOURce:SLEVel {<
Voltage
>|<
Current
>|
<
Temperature
>|<
Resistance
>|MINimum|
MAXimum}
:SOURce:SLEVel?
<Voltage>: Voltage output setting
<Current>: Current output setting
<Temperature>: Temperature output setting
<Resistance>: Resistance output setting
MINimum: Minimum value in the selectable range
MAXimum: Maximum value in the selectable
range
Example
:SOURCE:SLEVEL
-1V
:SOURCE:SLEVEL -> -1.00
Description • If you attach a minus sign to the setting, the
polarity is set to negative. If you attach a plus
sign or do not attach any sign, the polarity is
set to positive.
• Before setting <Voltage>, use the
:SOURce:FUNCtion command to set the
source function to VOLTage.
Before setting <Current>, use the
:SOURce:FUNCtion command to set the
source function to CURRent.
Before setting <Temperature>, use the
:SOURce:FUNCtion command to set the
source function to TCouple or RTD.
Before setting <Resistance>, use the
:SOURce:FUNCtion command to set the
source function to RESistance.
If you set an output setting of a different source
function, a “131: Invalid suffix” error will occur.
• If the source function is RJTemp and you set
the output setting, a “221: Setting conflict” error
will occur. 9.91E+37 is returned as a response
to a query.
• The selectable range changes depending
on the range setting of the voltage, current,
or resistance or the type setting of the
thermocouple or RTD. Set the voltage, current,
or resistance range with the :SOURce:RANGe
command. Set the thermocouple or RTD type
with the :SOURce:TYPE command.
:SOURce:TCouple?
Function
Queries all user-defined thermocouple settings.
Syntax
:SOURce:TCouple:?
