XP2i Operation Manual
Low Battery Indication
The Battery icon ( ) uses three bars to display the battery level. When the icon displays all three bars, the batteries are full. The XP2i will continue to operate
accurately while the icon is visible. When the batteries are exhausted, the letters
batt will appear across the display. After batt appears, no pressure measure-
ments will be possible until the batteries are replaced.
Battery replacement
The XP2i uses 3 AA batteries. Loosen the four rear panel screws to gain access to the battery compartment. These four panel screws are captive inside the
panel and are not removable. Pull the panel up to expose the battery compartment. After replacing the batteries, the XP2i will start operating immediately
(without having to press the
(
on/off
)
button). This indicates that a complete reset has occurred, and is normal.
