6 MAINTENANCE & CARE

For accurate readings keep your fingers away from, and avoid obstructing airflow through, the holes in the

casing around the humidity and air temperature sensors. Some time (~20 minutes) may be required to

acclimatise the gauge once it is brought from a cold into a warm environment or vice versa

Regular calibration checks over the life of the gauge are a requirement of ISO 9000 and other quality

procedures. For certification please contact Elcometer or your supplier.

The instrument does not contain any user-serviceable components. In the unlikely event of a fault, the

instrument should be returned to your local Elcometer supplier or direct to Elcometer. The warranty will be

invalidated if the instrument has been opened.

To avoid damage:

• When measuring surface temperature a light contact between the probe and the surface is sufficient -

DO NOT USE EXCESSIVE FORCE

• Do not drag the surface temperature probe over the surface

• Keep the gauge away from paint dust and dirt as much as possible as these can affect the long term

accuracy of the humidity sensor

• The gauge is dustproof and resistant to water jets and should not be affected by dust and moisture

under normal conditions, however, the gauge should not be submerged in liquids
