1. Correct Set Up and Calibration of Hemoflow 400
 The Hemoflow 400 is a sensitive medical device
 For optimum performance allow the Hemoflow 400 to adjust to the room temperature before
calibration
 If the device needs to be moved to the other side of the donation chair (for a donor using the
opposite arm), remove the Hemoflow 400 from the table before the move
 Dropping Hemoflow 400s can cause significant internal damage that may not be evident from
the outside
 Dropping the Hemoflow 400 directly onto its tray will cause damage to the load cell by pushing
the barb connectors upwards and directly affect the weighing function
 Calibration of a Hemoflow 400 is not a weight check, the user is telling the machine what 500g
equals
 Calibrate the device in a regulated environment i.e., wait for all other session set up to be
complete to avoid any movement that may affect the Hemoflow 400
 If possible, allow the Hemoflow 400 to adjust to room temperature before calibrating
 Do not write on the table while the device is calibrating
 Ensure there are no additional objects in or touching the tray
 Follow the on-screen instructions as they appear for best results
