"2.1.9.2 User LRV"
Factory setting: 0
Adjustment range: Freely selectable numeric value
Purpose: Setting the start of scale value
Description: This parameter allows the start of scale value for the user scaling to be set.
The value that is set for "2.1.2.1.2 Setting LRV" (Page 84) or "2.1.2.2.2 Set
LRV with Pressure" (Page 85) is automatically assigned to this value.
The start of scale value is expressed in the units you selected under "2.1.9.1
User Curve Unit" (Page 98).
"2.1.9.3 User URV"
Factory setting: 100
Adjustment range: Freely selectable numeric value
Purpose: Setting the full scale value
Description: This parameter allows the full scale value for the user scaling to be set. The
value that is set for "2.1.2.1.3 Setting URV" (Page 84) or "2.1.2.2.3 Set URV
with Pressure" (Page 85) is automatically assigned to this value.
The full scale value is expressed in the units you selected under "2.1.9.1
