6 .4 .2 Calibration of the Pump Manager C-615
Requirements:
To calibrate the Pump Manager C-615 you need a graduated cylinder and a stopwatch.
Set the pump flow rate to 100 ml/min and the time to one minute. Place the pressure tubing into the
graduated cylinder and start the pump. If the cylinder contains exactly 100 ml, the pump is calibrated.
If too little or too much solvent is in the cylinder, the flow rate is too low or too high. If this is the case,
recalibrate the pump.
Proceed as follows:
Select the function Calibration A and Calibration B in the Main Menu > Settings and increase or
decrease the percentage accordingly. Confirm by pressing the selector switch. The pump will now
deliver more or less solvent, accordingly. Repeat the measurement and check the current pump
performance.
If you have changed the pump flow rate during calibration, the correction values for A and B are
displayed on start-up of the Pump Manager.
