An extremely accurate laboratory comparison procedure is used
AND
The calibration points are a long way apart
If the laboratory comparison process provides uncertain results, carry out measurements for
several further calibration points. This allows the statistical error to be defined more exactly and
thus taken into account.
Non-linear calibrations - which may need to be separated into several segments - consequently
require more calibration points.

O Note: You can refine a calibration by measuring further samples later on. In particular, this is
necessary if the product is subsequently measured in a different value range.
6.2 Logging in to carry out calibration or create products
To create new products or carry out a calibration for a product, you must first log in with appro-
priate rights (calibration requires at least level 3 and creating new products requires at least level
4). This prevents the unauthorized changing of system settings, which could result in incorrect
measurement results.
1. Select the Change user menu item.
2. On the Login screen, enter your user name and password.
3. Click Apply.
The Calibration, Product settings, System settings, and Service functions are now available.
O Note: After carrying out administrative work, you should either change your login to your "normal"
access rights or, if a default user is defined, turn off the device to prevent unauthorized modifica-
tions of the system settings or calibrations.
6.3 Creating a product
You must make appropriate product settings on the device for each product for which moisture
or density is to be measured.
