116 Programming the VT1422A for Data Acquisition and Control  
Supplying a Fixed Reference Temperature
The [SENse:]REFerence:TEMPerature <degrees_c> command 
immediately stores the temperature of a controlled temperature reference 
junction panel in the Reference Temperature Register. The value is applied 
to all subsequent thermocouple channel measurements until another 
reference temperature value is specified or measured. There is no need to use 
SENS:REF:CHANNELS.
To specify the temperature of a controlled temperature reference panel:
SENS:REF:TEMP 50
reference temp = 50
 °
Now begin scan to measure thermocouples.
Linking Strain
Measurements
Strain measurements usually employ a Strain Completion and Excitation 
SCP (VT1506A, VT1507A, VT1511A) or VT1529A/B Remote Strain 
Conditioning Unit. To link channels to strain EU conversions send the 
[SENSe:]FUNCtion:STRain:<bridge_type>   [<range>,](@<ch_list>)
<bridge_type> is not a parameter but part of the command syntax. The 
following table relates the command syntax to bridge type. See the 
VT1506A, VT1507A, and VT1511A SCPs’ user’s manual for bridge 
schematics and field wiring information.
*   These choices are only available with the VT1529A/B.
** This choice is only available with VT1529A/B channels that have had a 
 user-supplied resistor installed.
The <ch_list> parameter specifies which sense SCP channel(s) to link 
to the strain EU conversion, not the strain bridge completion SCP 
channels. This parameter does not specify channels on the 
VT1506A/07A Strain Bridge Completion SCPs. It can specify any of 
the lower four channels of a VT1511A SCP since these channels are 
the sense channels used to measure the SCPs four bridge completion 
channels.
