9. Maintenance

Periodic evaluation of the desiccant is vital for keeping the vent tube dry. To

assess the effectiveness of the desiccant, use one of the following:

• An indicating desiccant that changes color when it’s losing its drying

power

• An enclosure humidity indicator such as our #6571 humidity indicator

card

9.1 Every Visit, At Least Monthly

• Collect data

• Visually inspect wiring and physical conditions
