Important Note: Avoid handling the black face of the sensor cap. Do not use alcohol or
other organic solvents to clean the black face of the sensor cap. These solvents will
destroy the sensor cap.
3. Pull to open the iButton ® 1 cover on the pressure-sensor module ( Figure 1 on page 2 .)
Tip the module to remove the existing iButton.
4. Insert the new iButton with the label facing up.
5. Close the iButton cover and press until it seats against the surface of the module
housing. The cover must be closed properly to ensure good electrical contact with the
iButton to ensure a proper seal.
