Nibp Calibration - GE B30 Technical Reference Manual

4.4.1 NIBP Calibration

Active Leak Test: Wrap an adult cuff around a pipe
and connect the cuff to the module. Select the
active leak test (ON). The module automatically
pumps a pressure of 280 mmHg into the cuff. Wait
for several seconds until the pressure stabilizes.
Then check that the pressure reading does not drop
more than 5 mmHg per minute. If it does, leaking
point(s) should be detected and fixed. Cancel the
test by selecting the Active leak test OFF.
Calibration Check: After the calibration check is
selected , the module zeroes the pressure
transducers at the beginning of the calibration
check. Do not pump pressure until the text
'Calibrating' appears in the NIBP digit field or the
zeroing will fail. After the zeroing is done, manually
pump pressure into the module and make sure that
the same pressure values are shown both on the
display and on the manometer. Pressure of both
pressure channels B1 and B2 are shown. The
pressure values are automatically
zero-compensated, so the readings of B1 and B2 should be the same as the manometer readings.
Protection: Software calibration protection (ON/OFF). Select OFF when calibrating. Protection selection
becomes available in the menu after pressing the NIBP module buttons
simultaneously for 3 seconds.
How to calibrate
NOTE: Perform NIBP Calibration Check first to evaluate if calibration is needed or not.
NOTE: Both channels B1 and B2 must be calibrated simultaneously.
NOTE: The module must be in the frame during the whole procedure.
NOTE: Calibration selection is available only when protection is OFF.
1. Press the NIBP module buttons
seconds to enable the Protection selection - the color of the Protection selection
changes from grey to white.
NOTE: Make sure that you are using the module keys and not the side panel keys of the
monitor.
NOTE: When the buttons have been pressed, the message 'Calibration switch on!' is shown in
the NIBP digit field.
2. Change the protection setting from ON to OFF to enable the Calibrate selection - the
color of the Calibrate selection changes from grey to white.
NOTE: When calibration has been enabled, the message 'Calibration not protected' is shown in
the NIBP digit field.
3. Zeroing:
