Specifying.the.settings:
PVmin X x/x
lower.scaling.value.for.the.process.actual.value
1... S elect.the.unit.for.the.flow-rate
The unit on the display has a dark background.
Press the up arrow key (+) to select from the following units:
l/s, l/min, l/h, m³/min, m³/h, UG/s (gal(US)/s), UG/min (gal(US)/min), UG/h (gal(US)/h), IG/s (gal(Imperial)/s),
IG/min (gal(Imperial)/min), IG/h (gal(Imperial)/h).
2... I nput.the.position.of.the.decimal.point
Press the down arrow key (←) to highlight the decimal point with a dark background.
Press the up arrow key (+) to specify the position.
3... I nput.the.lower.scaling.value.for.the.process.actual.value
Press the down arrow key (←) to highlight the individual digits with a dark background.
Press the up arrow key (+) to set the value.
Adjustment range: 0 – 9999
This setting specifies the reference range for the dead band of the process controller as well as for the analogue
feedback of the process actual value (option).
PVmax X x/x
upper.scaling.value.for.the.process.actual.value
The unit for flow-rate and the position for the decimal point is transferred from the inputs of the lower scaling
value.
1... I nput.the.upper.scaling.value.for.the.process.actual.value
Press the down arrow key (←) to highlight the individual digits with a dark background.
Press the up arrow key (+) to set the value.
Adjustment range: 0 – 9999
This setting specifies the reference range for the dead band of the process controller as well as for the analogue
feedback of the process actual value (option).
K-Factor
→ VALUE
1... I nput.the.position.of.the.decimal.point
The decimal point on the display is highlighted with a dark background.
Press the up arrow key (+) to set the position.
Adjustment range: 1 or 2
2... I nput.the.K.factor
Press the down arrow key (←) to highlight the individual digits with a dark background.
Press the up arrow key (+) to set the value.
Adjustment range: 0 – 9999
K-Factor → TEACH IN
Calculating the K-factor by measuring a specific flow rate.
Hold down the selection key on the right (ENTER) for approx. 3 s
