Remote Operation
Query the Current Source Voltage :SOURce:VOLTage:VALue?
Returns the current source voltage followed by the system voltage unit of measure.
Example: :SOUR:VOLT:VAL? returns the output value, e.g. +1.456000V.
Query the Overload Status :OUTPut:OVERload?
If there is an overload, the Model 1140A returns a 1; if not, a 0.
Example: :OUTP:OVER? will return 0 for no overload.
Change Standby Status :OUTPut:STANdby {Standby Status}
{Standby Status} must be OFF or ON.
Example: :OUTP:STAN ON will put the unit in standby mode
Query the Standby Status :OUTPut:STANdby?
Returns OFF or ON.
Example: :OUTP:STAN? will return ON for standby mode.
Meter-mode Query
Query the Value Measured by the Model 1140A in Meter Mode :SENSe:VALue?
This is returned as a string containing the number followed by the unit of measure currently
used for that value.
Example: :SENS:VAL? returns the presently measured value, e.g. +234.56C.
Thermocouple Commands and Queries
Query Available Thermocouple Types :INSTrument:THERmocouple:TYPE:CATalog?
Returns a comma-delimited string of available thermocouple types.
Example: :INST:THER:TYPE:CAT? returns
B-MN175,R-MN175,S-MN175,E-MN175,J-MN175,K-MN175,N-MN175,
T-MN175,PLII,G,C,D.
If using IPTS-68 instead of ITS-90, this query returns
B-MN125,R-MN125,S-MN125,E-MN125,J-MN125,K-MN125,N-MN161,
T-MN125,PLII,G,C,D.
Set the Thermocouple Type :INSTrument:THERmocouple:TYPE {Type}
{Type} must be a type in the catalog of the available thermocouple types (see above).
Note: If the thermocouple type is changed without changing the simulation temperature, an
error could result if the current simulation temperature is out of range for the new
thermocouple type. The same can happen if the simulation temperature is set first but the
new simulation temperature is outside the range of the old thermocouple type.
