Remote Operation
Setting either the thermocouple type or the simulation temperature first will usually resolve
the issue, but not always. There are pairs of thermocouple types for which neither the new
nor the old simulation temperature will be within range of both new and old thermocouple
types.
The solution is to first set the simulation temperature to a temperature from 250°C to 400°C
(482°F to 752°F, 523.15 K to 673.15 K, or 941.67°R to 1211.67°R), then change the
thermocouple type, and finally set the simulation temperature to the desired value. This
range of temperatures is within all supported thermocouple types and hence will not result in
an error.
Example: :INST:THER:TYPE R-MN175 sets the thermocouple to Type R per NIST
Monograph 175.
Query the Active Thermocouple Type :INSTrument:THERmocouple:TYPE?
Returns the thermocouple type currently in use.
Example: :INST:THER:TYPE? returns B-MN175, for example.
Set the Thermocouple Offset Unit of Measure
:UNIT:THERmocouple:OFFSet {Temperature unit of measure}
{Temperature unit of measure} must be C, F, R, K, or SYSTEM. If SYSTEM is entered, the
thermocouple offset will use the present system temperature unit of measure. When the
offset unit of measure is changed, the offset value may change, e.g. if the value is 4 and the
unit of measure is changed from °C to °F, the value will change to 7.2. No change will occur
when the unit of measure is changed from °F to °R or from °C to K.
Example: :UNIT:THER:OFFS C sets the offset unit of measure to Celsius.
Query the Current Thermocouple Offset Unit of Measure :UNIT:THERmocouple:OFFSet?
Returns C, F, R, or K.
Example: :UNIT:THER:OFFS? could return F.
Set the Offset for the Current Thermocouple Type
:INSTrument:THERmocouple:OFFSet:VALue {Temperature value}
{Temperature value} must be within the range of −5 to +5 for temperature in Celsius and
Kelvins and −9 to +9 for temperature in Fahrenheit and Rankine. If the offset unit of
measure is later changed, the offset value may change: e.g. if the value is 4 and the unit of
measure is changed from C to F, the value will change to 7.2. No change will occur when
the unit of measure is changed from F to R or from C to K. Note that separate offsets are
stored for each thermocouple type.
Example: :INST:THER:OFFS:VAL 3.4.
Query the Thermocouple Offset Value :INSTrument:THERmocouple:OFFSet:VALue?
Returns the offset temperature followed by its unit of measure as a single character.
