4.2.2.2 Set Conversion Times

Setting the conversion times allows the user to customize the amount of measurement time for conversions. Typically, for the INA233EVM 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 4-5.
