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
