Open the Device

Open the device to replace or inspect the battery as well as to inspect the

interior components such as the O-rings and device electronic contacts.

! Note

Before opening the device, remove it from the field and operating

environment.

To prevent damage to the O-rings, turn the e-module retaining ring

counterclockwise ½ to one turn, and then clockwise about ¼ turn, and

repeat until the sensor body O-ring is exposed.

Refer to the “Install Battery” section for more information regarding how to

open VP Series 2000 devices.

If you have trouble removing the retaining ring, the e-module may be

rotating with the retaining ring. Turn the retaining ring clockwise slightly and

press down lightly on the e-module to hold it in place. Then turn the

retaining ring counterclockwise.

Inspect the E-Module

Remove the e-module by pressing upward lightly on the side opposite the

module’s contact pins.

To ensure that the e-module (top of the device) remains in good operating condition:

• Visually check that the enclosure, battery terminal spring, and contact pins are undamaged.

• Inspect the e-module positive battery terminal spring. Look for chemical corrosion or deposits.

• Verify that the e-module contact pins move freely when pressed against the sensor module contact

pads.

• Visually check that the e-module housing is not cracked or otherwise degraded.

Inspect the Battery

Before removing the battery with the battery installation tool, look for signs of battery leakage.

! CAUTION

CORROSIVE CHEMICAL HAZARD

If a battery has leaked, do not touch the corrosive electrolyte.
