1 or ON Enable offset compensated ohms
:OCOMpensated? Query state of offset compensated ohms
This command is used to enable or disable the offset compensated ohms feature. Offset com-
pensation is used to cancel the effects of offset voltages (such as thermal EMFs) when making
resistance measurements. Offset compensation is explained in detail in paragraph 2.4.3 (OFF-
SETCOMP).

:DTCouple commands

The following commands are used to make differential thermocouple temperature measure-
ments using the Model 1801 Nanovolt Preamp. Refer to the instruction manual for the Model
1801 for details.
:TYPe <type>
[:SENSe[1]]:TEMPerature:DTCouple:TYPE <type>
<type> = J Set operation for Type J thermocouple
K Set operation for Type K thermocouple
T Set operation for Type T thermocouple
E Set operation for Type E thermocouple
R Set operation for Type R thermocouple
S Set operation for Type S thermocouple
B Set operation for Type B thermocouple
N Set operation for Type N thermocouple
USER Select user-defined slope for other type of thermocouples
:TYPe? Query DTC type
This command is used to set thermocouple type for differential thermocouple measurements
using the Model 1801 Nanovolt Preamp. Selecting one of the seven standard thermocouples (J,
K, T, E, R, S, B, or N) requires that you specify the reference temperature for the reference ther-
mocouple using the :RTEMperature command.
When using other thermocouple types (USER selected), you must specify the thermocouple
slope (coefficient) using the :USLope command.
Refer to the Model 1801 Nanovolt Preamp Instruction manual for details on making differential
thermocouple temperature measurements.
