9.6 Calibration
The dosing flow display is set by default for an operating
counter-pressure of 3 bar. Calibration can be used to set the
pump flow to the actual operating conditions.
Calibrate the pump under normal operating conditions with the
discharge line connected and at operating counter-pressure.
"OFF CAL" appears in the display.
1. Press the "Up" button.
– "- - -" and "CAL" (flashing) appear in the display.
2. Wait until "ON" and "CAL" (not flashing) appear in the display.
– "ON CAL" appears in the display.
3. Press the "Start/Stop" button.
– Calibration is started. The LED flashes green and "Run"
flashes in the display.
• 200 strokes are performed by default. The number of strokes
performed appears in the display.
• Press "Start/Stop" to stop at any stroke value.
– The LED lights up red.
4. Press the "Start/Stop" button.
The current calibration value is displayed (not with replacement
circuit boards!).
5. Use the "Up" and "Down" buttons to enter the calibration
value (gauged volume in ml).
• Press the "Menu/Info" button (confirm the setting and move on
to the next menu item), or
• press the "Start/Stop" button (confirm the setting and close the
second function level).
Fig. 30 Calibration
With activated flow compensation (see section
4.4.4 Flow compensation):
When dosing media with a viscosity different
from water or after a software update the pump
has to be calibrated. After a software update
"cal" is flashing in the display.
The dosed volume must be gauged in litres
during calibration, e.g. by drawing the dosing
medium from a gauged tank.
The calibration process does not change the
setting for the assignment/weighting of the
current input and output for the flow rate.
If a current input or output is used, check after
calibration to determine whether a new current
weighting is required.
