The
key was selected. A
calibration window is opened (bottom section
of the menu).
Function of the Software Keys und Icons
The function of the software keys und icons during calibration are
as follows:
The max. number of calibration points is displayed, e.g. three
calibration points. Click on key: the number of calibration points can
be modified with the -/+ keys. We recommend keeping the
suggested number or increasing only, do not decrease the number.
The actual calibration point is displayed, e.g. first calibration point.
The suggested reference value is displayed for the first calibration
point.
If the reference value key is pressed, an input keypad is displayed.
The value from the measurement instrument can be entered. The
entered value must be in the permissible limits (e.g. –100 to 500
mmHg).
The entered value can be cancelled and the window is closed.
The entered value can be confirmed with the OK key and the
window is closed.
The calibration point with the entered calibration value can be
confirmed and the calibration value is saved. The sensor values must
be checked in therapy mode (service overview) after calibration.

The calibration procedure is completed and the new calibration data
are stored in the LLC and LLS.
Note:
Pay attention to the LLC and LLS status windows. The bit
sequence 0-1-0 must be identical in the LLC and LLS status
windows during the saving procedure. The calibration data is
saved only after the bit sequence 0-1-0 (see figure).
Save the calibration data to the compact flash card before exiting
the TSM service program: TSM Main Menu, File Operations, Save
Calibration Data.
A calibration procedure can be terminated. The existing calibration
data are maintained in the LLS and LLC.
