[SENSe:]STRain:UNSTrained
[SENSe:]STRain:UNSTrained <unstrained_v>,(@<ch_list>) specifies the
unstrained voltage value to be used to convert strain bridge readings for the
channels specified by <ch_list>. This command does not control the output voltage
of any source.

·
Use a voltage measurement of the unstrained bridge sense channel to determine
the correct value for <unstrained_v>.
·
The <ch_list> parameter must specify the channel used to sense the bridge
voltage, not the channel position on a Bridge Completion SCP.
