CHAPTER 5

MAINTENANCE

This chapter provides information that is needed in basic maintenance of

the product.

Periodic Maintenance

The humidity measurement accuracy of the HMP60 and HMP110 should

be calibrated yearly. When calibration indicates that accuracy is not

within specification:

- HMP60: change the INTERCAP® Sensor.

- HMP110: adjust the measurement yourself, or have it adjusted at a

Vaisala Service Center.

Light cleaning of the probe, and replacement of the filter should be done

only when necessary.

Cleaning

The probe body can be wiped clean with a soft, lint-free cloth moistened

with mild detergent. Do not use solvents or compressed air.

Note that wiping the membrane filter or stainless steel sintered filter may

block its pores and/or deposit residue on the filter. If the filter is heavily

contaminated, replace it.
