adds shunt resistance to one leg of bridge
on Strain Bridge Completion SCPs and the VT1529A/B Remote Strain Bridge unit.
This can be used for diagnostic purposes and characterization of bridge response.
Parameters
Comments
•
If <ch_list> specifies a non strain SCP, a 3007 "Invalid signal conditioning
plug-on" error is generated.
•
Only one channel on any one VT1529A/B can be specified in <ch_list> . This
is because a single resistor is used to shunt each of a VT1529A/Bs 32 channels.
The
<ch_list> may specify one channel on each of several VT1529A/Bs.
