Shunt control

Shunt control allows installation and removal of shunt resistors during a test run. If the current test contains one or more applicable channels, click Shunt.... The Shunt Control dialog is presented.

To install the shunts on all applicable channels, which is every channel in the test defined using one of the Bridge sensor input modes, select Normal or Opposite shunt mode.

NOTE
The Normal mode is based on the System preferences Bridge shunt polarities parameter set unless the bridge channel is configured to use the internal shunt resistor scaling mode. In this case, the Normal mode is the polarity defined in the sensor scaling configuration.

NOTE
Shunt polarity is based on electrical units scaling (i.e., mV/V scaling). If the sensor scaling slope is negative, the shunt polarity in output units is in the opposite direction. For example, the Up Scale option would result in a negative swing in the physical units output data.

To remove the shunts, select Remove shunt.

All shunt resistors are removed at the start of a new test.

NOTE
The Shunt Control dialog can remain open while navigating the web application and closes automatically at the end of the test run. (It is also closed if the web browser is reloaded or refreshed.)
