OUTPut
OUTPut:POLarity?
OUTPut:POLarity? (@<channel>) returns the polarity on the digital output channel
in <channel>.
Parameters
Comments •
The <channel> parameter must specify a single channel.

OUTPut:SHUNt
OUTPut:SHUNt <enable>,(@<ch_list>) 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.
