Hold the scanner close to, or touching the animal.
Scan slowly and repeatedly over the entire body to ensure whether or not a microchip is present. Wave the scanner back and forth lightly while scanning, because microchips can be in various locations within the animal. Scan first in a horizontal, then a vertical "S" pattern down the animal's body, as shown in the diagram. Consider scanning each animal more than once to ensure any present microchip can be localized by the scanner
