Levelling
To function properly, the moisture analysermust be precisely horizontal.
The instrument is fitted with one spirit level and two adjustable feet for level-control, with the aid of which
it is possible to compensate for small height differences and/or unevennesses in the surface on which the
moisture analyser is standing.
The two screw feet must be adjusted so that the air bubble is precisely in the centre of the sight glass of the
bubble level.
5.8
Weight Adjustment
Since the Earth's gravity is not the same everywhere, each balance must – in accordance with the underlying
physical weighing principle – be adjusted to compensate for the gravity at each location. This adjustment
process must be carried out on initial installation and after each subsequent relocation. In order to get exact
measurements, it is recommended moreover, that the balance should also be calibrated periodically or ad-
justed if necessary.
The adjustment is effected in the configuration menu. This may be done externally, internally or automati-
cally (see chapters 13.3 "Configuration - Adjustment" and 16.2 "Adjustment").
With the aid of the “Intelligent Adjustment Mode” the balance can itself determine the size of the calibration
weight, which enables an exact adjustment with different size weights (in 10 g).

Switching on the Moisture Analyser
• Press «
ON/OFF
» to switch on the instrument
During the start-up sequence the moisture analyser executes a self check routine and stays, after about five
seconds, ready in the same method before its last switching-off.
5.10 Auto-Standby Mode
The moisture analyser is equipped with an Auto-Standby mode, which can be activated or deactivated in the
configuration menu.
If the Auto-Standby mode is activated, the moisture analyser automatically switches to Standby some time
after the last weighing or key operation (current-saving function).
The delay before switching to Standby is defined in the configuration menu ( 13.2 "Configuration - Weighing
parameters").
• Press any button or put on a weight in order to switch the moisture analyser from the Standby mode back
to the normal operation mode again.

Correct
NOTE
In order to get exact measurements, the moisture analyser must again be carefully levelled after each re-
location.
NOTE
The moisture analyser must be adjusted on initial installation and after every relocation.
If you work in accordance with “Good Laboratory Practice GLP” observe the prescribed intervals between
calibrations respectively adjustments.
