If the error of pressure channel B1 is larger than specified above, the module should be
recalibrated. The error of B2 is allowed to be even twice as large because it has no effect on blood
pressure measurement accuracy. However, it is recommended to recalibrate the module also when
the error of B2 is larger than specified above to ensure best possible operation.
Calibration
1.
Enter Calibration menu.
2.
Remove hoses from front panel connector to enable proper zeroing.
3.
Select
Calibration
. If it is not available, perform the steps A, B and C.
NOTE: Do not pull out the NIBP module from the monitor frame. The module must be in the frame
during the whole procedure.
A)
Turn the toggle switch at the bottom of the NIBP module to enable the calibration.
Turn the switch to the right by, for example, a sharp pencil. This enables menu
selection ‘Protection’. the message ‘Calibration switch ON!’ appears.
B)
Select Protection OFF in the Calibration menu and press the ComWheel.
C)
Return the toggle switch to the left. Menu selection
Calibration
is now enabled, and
Protection
is disabled. When the calibration is enabled, a message ‘Calibration not
protected’ appears.
4.
Start Calibration by pressing the ComWheel. Messages ‘ZEROING’ and ‘ZEROED’ will appear
in the NIBP message field. After this a pressure bar will appear.
5.
Connect an external mercury manometer with pump to module through the both tubes of
the hose - both transducers B1 and B2 must be calibrated simultaneously. Pump up to a
pressure about 200 mmHg according to the manometer. Calibration is possible in the range
150 to 300 mmHg.
6.
Verify that both pressure values in the prompt field match the manometer reading. If not,
adjust by turning the ComWheel. When the values of the pressure bar and the manometer
are equal, press the ComWheel to confirm the calibration. The message ‘Calibrating’ will
appear onto the NIBP digit field. After a few seconds it is followed by ‘Calibrated’, which
means that the calibration has succeeded, and the new calibration data has been saved
into EEPROM.
To set the protection on:
Turn the toggle switch to the right. Select
Protection
ON and press the ComWheel. Then turn
the toggle switch back to the left.
7.
Remove the module from the frame and plug it back again. Then perform Calibration Check
(see the preceding page) to verify the new calibration.
