All three operating modes can also be limited to only measuring certain components of the device, as
shown in
Figure 17 . It is important to note that for complete functionality of the INA230, a configuration
must be chosen with Shunt and Bus configuration. Failure to choose Shunt and Bus configuration disables
a considerable portion of the unit functionality as discussed in the
INA230 data sheet .

The Configure Operation step also contains a drop down box for selecting the Averaging Mode. The
INA230 can be setup to take the average of several measurements before storing the value of the
measurements in the register table.
5.2.3 Set Conversion Times
Setting the conversion times allows the user to customize the amount of measurement time for
conversions. Typically, for the INA230EVM software, the user is not able to notice a visual difference
between the conversion times unless a high averaging mode and conversion time are chosen. The Shunt
and Bus conversion times can be set as shown in
Figure 18 .
