12.1.4

Parameterization of the scale

The scale is parameterized prior to the verification in accordance with the envisaged use.
The scale is checked and sealed during the verification. The parameters relevant to the
verification cannot be changed after the verification. These are mainly the parameters in the
data record DR 3. These read/write parameters are identified by "rwP" (read/write protected)
in the parameter tables in section "Scale parameters and functions". Certain commands
cannot be used after the verification either. These are identified in the command table by
"P".
12.1.5

Adjustment and preliminary checking of the scale

During commissioning, the scale adjustment (detailed description → Calibration (Page 76)) is
carried out following input of the scale parameters.
Depending on the type and the area of use, the scope of operations for checking the
measuring properties of the scale prior to the verification may be different. A preliminary
check with various calibration weights should always be carried out.
12.1.6

Calibration label

The calibration labels are edited based on the templates from the calibration set, and
subsequently printed. The fields in the calibration labels can already be provided with the
corresponding values prior to the verification. The protective foil is attached during the
verification.

12.2.1

Checking of parameters relevant to the verification

The scale parameters are set/checked using the SIMATIC HMI operator panel.
1. Call up the main menu (function key with the open-end wrench).
2. Select the "Setup" submenu in the main menu. Select the "Advanced scale parameters"
function key in the "Setup" menu.
3. The currently effective calibration parameters are shown in the display "Advanced scale
parameters 1 of 4" and on the following 4 pages. If the write protection of the calibration
parameters is activated (jumper between the connection points P-PR), a "lock symbol" is
displayed next to each protected parameter.
You can use the "Calibration check" submenu during the verification.
