Instructions
Tap the "Y" button on your controller to equip the PKE Meter.
Aim at the ghost or object you want to scan. Your proximity to the object determines which of the three connected rings on your PKE Meter screen is lit. If the outer ring is lit, you will get a 25 percent scan; if the middle ring is lit you will receive a 50 percent scan and if the inner ring is lit you will achieve a 100 percent scan. Each scan level gives you additional information on the object you're scanning, with a 100 percent scan giving you all available information.
Hold in the right trigger on your controller to start the scan. Do not release the trigger until the scan is complete.
