Calibrate Pump - Heidolph Hei-FLOW Value Originalbetriebsanleitung

Operation
Speed and tube diameter result in a minimal volume. Lower volume
can only be performed by using smaller tubes.
Large tubes and to little flow will result in an error feedback (see
chapter "Troubleshooting, Possible errors and how to resolve").

Calibrate pump

Tubes have individual manufacturing tolerances. If high dosing accuracy is required the
pump has to be calibrated for the tube in use by flow and/or by volume.
✓ Unit is switched on.
✓ Media to be dispensed is connected to pump.
✓ Pump head and inner diameter of tube are set correctly.
Calibrate pump with flow
✓ Indicator light „Flow ml/min" is illuminated.
✓ Required flow ml per minute is set.
➜ Press „Cal" key.
✓ Display starts blinking.
➜ Press rotation key.
✓ The pump dispenses for exactly 1 minute.
➜ Measure dispensed volume.
➜ Set measured flow via arrow keys
➜ Press „Cal" key for a minimum of 3 seconds to confirm.
✓ Pump is calibrated for flow ml per minute.
Verify set flow after calibrating. If applicable adjust flow.
Calibrate pump with volume
✓ Indicator light „Vol ml" is illuminated.
✓ Required volume is set.
✓ Speed is set via setting flow ml/min.
➜ Press rotation key.
➜ Measure dispensed volume.
➜ Press „Cal" key.
➜ Set measured volume via arrow keys
➜ Press „Cal" key for a minimum of 3 seconds to confirm.
✓ Pump is calibrated for volume.
If the calibrated values show a deviation > 30% most probably pump
head or tube diameter are not set correctly. Or the tube mounting
needs to be adjusted.
In this case cancel calibration via „Select" key. Verify your settings.
