channel in < ch_list > to the reference junction temperature EU conversion based on
< sensor_type > and < sub_type
Reference Temperature Register, and by default the FIFO and CVT. This is a
resistance temperature measurement and uses the on-board 122 µA current source.
The reference junction temperature value generated by scanning the reference
channel is stored in the Reference Temperature Register. This reference temperature
is used to compensate all subsequent thermocouple measurements until the register is
overwritten by another reference measurement or by specifying a constant reference
temperature with the
SENSe:REFerence:TEMPerature
reference junction channel must be scanned before any thermocouple channels.

The < range > parameter: The HP E1413 has five ranges: .0625 VDC, .25 VDC,
1 VDC, 4 VDC, and 16 VDC. To select a range, simply specify the range value
(for example, 4 selects the 4 VDC range). If you specify a value larger than one of
the first four ranges, the HP E1413 selects the next higher range (for example, 4.1
selects the 16 VDC range). Specifying a value larger than 16 generates Error -222,
"Data out of range" . Specifying
AUTO selects autorange. The default range (no range parameter specified) is
autorange. Autorange is not allowed while
Error +3072, "Autorange not allowed with SENSE:FILTER on" will be generated at
INITiate:IMMediate time if the filter is
range may be specified in millivollts (mv).

If you are using amplifier SCPs, you should set them first and keep their settings
in mind when specifying a range setting. For instance, if your expected signal
voltage is to be approximately .1 VDC and the amplifier SCP for that channel has
a gain of 8, you must set
