Abstract: An infusion device includes a pump device having a housing and a flexible wall section together forming a channel extending along a channel length between first and second ends. An actuation device locally depresses the flexible wall section in a vertical direction, and is displaceable along the vertical direction. To pump a fluid through the channel, the actuation device is actuated to depress the flexible wall section at a depression location, the depression location during one pump cycle moving along the channel length. To calibrate the infusion device, the position of the actuation device along the vertical direction during one pump cycle is measured to obtain a measured profile, a difference between the measured profile and a prestored nominal profile is formed to obtain a difference profile, and from the difference profile a characteristic value for correcting and/or checking the pump operation of the infusion device is calculated.
