"1.1.10.2 Mass LRV"
Factory setting: 0 kg
Adjustment range: Freely selectable numeric value
Purpose: Setting the start of scale value
Description: This parameter allows the start of scale value for the mass scaling to be set.
The value that is set for "1.1.3.1.2 Setting LRV" (Page 69) or "1.1.3.2.2 Set
LRV with Pressure" (Page 70) is automatically assigned to this value.
The start of scale value is expressed in the units you selected under
"1.1.10.1 Mass Unit" (Page 79).
"1.1.10.3 Mass URV"
Factory setting: 1000 kg
Adjustment range: Freely selectable numeric value
Purpose: Setting the full scale value
Description: This parameter allows the full scale value for the mass scaling to be set.
The value that is set for "1.1.3.1.3 Setting URV" (Page 70) or "1.1.3.2.3 Set
URV with Pressure" (Page 71) is automatically assigned to this value.
You can enter the end of scale value in the unit selected under "1.1.10.1
Mass Unit" (Page 79).
"1.1.10.4 Level Curve"
Use this submenu to activate a level characteristic which you defined under the following
parameters.
Table 6- 4 "1.1.10.4.1 Curve Activation"
Factory setting: Off
Adjustment range:
•
Off
•
On
Purpose: Activate / deactivate the level characteristic
Only if "1.1.10.4.1 Curve Activation" is set to "On" are the following parameters visible.
Table 6- 5 "1.1.10.4.2 Curvepoint Number"
Factory setting: 30
Adjustment range:
•
Min. 2
•
Max. 30
Purpose: Input the number of the level curve points used
Description: For the vessel in which the mass is being measured, enter a characteristic
that describes the geometry of the vessel. This parameter allows you to
input the number of curve points that are used.
