4.2 Selecting the location

Measurement performance of your moisture analyzer depends largely

on the surrounding environments.

Follow these guidelines to make sure the proper environmental

conditions are met:

Operate the instrument only indoors.

Make sure that all parts of the instrument reach room temperature

(5

°

C-30

°

C) before switching it on. Make sure that the relative humidity is

between 20% and 80% and that non-condensing conditions are met.

The power plug must be easily accessible.

Select a firm, horizontal location that is free from vibrations as

possible.

Avoid direct sunlight.

No excessive temperature fluctuations.

Surroundings should be as free from dust as possible.

Sufficient clearance around the instrument to allow warm air to

dissipate.

Sufficient distance from heat-sensitive materials in the vicinity of the

instrument.
