15.5.2 Volume flow lower-range value
This function allows the operator to set the lower-range value for volume flow. The lower-range
value takes on the unit defined using the Volume flow unit function. The lower-range value will
scale the current and frequency outputs assigned to volume flow. After choosing the Volume
flow lower-range value function and pressing enter, the following selection field will be display
QV LRV = 0%
XXXXX.XX l/h
The current lower-range value for volume flow will be displayed. According to the description
in Section 14.1.3.2 Input window / modify a value, the current value can be changed.
15.5.3 Volume flow upper-range value
This function allows the operator to set the upper-range value for volume flow. The upper-
range value takes on the unit defined using the Volume flow unit function. The upper-range
value will scale the current and frequency outputs assigned to volume flow. After choosing
the Volume flow upper-range value function and pressing enter, the following selection field
will be display
QV URV = 0%
XXXXX.XX l/h
The current upper-range value for volume flow will be displayed. According to the description
in Section 1.2.3.2 Input window / modify a value, the current value can be changed.
