Servicing - CareFusion MicroRPM Benutzerhandbuch

Please Note: Calibration can only be adjusted in a positive direction,
as the MicroRPM measures the highest peak value. Therefore, if the
reading was greater than that on the Water Manometer, the
calibration screw must be turned anti-clockwise first, before
calibration is attempted.
Serial
port
To calibrate the MicroRPM, connect to the Water Manometer as
before, filling the syringe to obtain the required negative pressure. To
change the calibration, slowly turn the calibration screw in a clockwise
direction until the same value is displayed on the MicroRPM.
