CHAPTER 5

MAINTENANCE

This chapter provides information that is needed in basic maintenance of

the HMW90 series.

Periodic Maintenance

Cleaning

The body of the transmitter can be cleaned by wiping with a moistened

lint-free cloth. Do not use cleaning agents or solvents, or blow

pressurized air into the transmitter housing.

Do not attempt to clean contaminated HTM10 modules and HUMICAP

sensors. Dirty modules should always be replaced with new calibrated

modules.
