6. Maintenance
The DIFF is a precision-instrument. Simple routine checks will ensure that the DIFF will function
for many years.

Remove moisture with a clean moisture absorbent cloth before storing the DIFF.

Remove the batteries when the DIFF isn’t used for a long time.

Store and transport the DIFF always in the included transport case.

Store the DIFF in dry conditions.

Let the DIFF adjust to the ambient temperature. The DIFF will adjust faster when it is hold
against an exhaust vent.

Never remove the grills inside the DIFF.

Check the DIFF periodical for cracks.

Do not expose the DIFF to water

Do not use aggressive detergents. This will damage the DIFF.

Do not expose the hoods to sharp objects. A damaged hood can give wrong
measurements.

Observator recommends yearly calibration of the DIFF. Contact our service department
( service@observator.com ) for the calibration.
