3.26 UNIT Subsystem
The UNIT subsystem (see Table 3-17) is used to select measurement units for temperature read-
ings.
:TEMPerature <name>
:UNIT:TEMPerature <name> Select temperature units
Parameters <name> = C or CEL °C temperature units
F or FAR °F temperature units
KK temperature units
Query :TEMPerature? Query temperature units
Description This command is used to select the units for temperature readings (internal and external). This
command controls the temperature reading units for the multiple displays, buffer readings and
readings sent out over the bus.
