3. Connect an external mercury manometer with a pump to the module through the both
tubes of the hose. Pump up to about 200 mmHg pressure (range of 150 to 300 mmHg
allowed) according to the manometer. Verify that both pressure values in the prompt field
match the manometer reading. If not, adjust by turning the ComWheel.
4. When the values are equal, push the ComWheel to confirm the calibration. After a few
seconds the ‘Calibrated’ message will appear in the NIBP digit field, which means that the
calibration data has now been saved.
NOTE: When calibrating NIBP, always change the displayed pressure value slightly with the
ComWheel, even in cases where the value would be correct. For example, change the value
one step higher and then back one step lower. The ‘Calibrated’ text should appear in the
display. This ensures that the calibration procedure is correctly registered and stored by the
module.
5. Use the module buttons again to enable Protection setting and set it ON, and finally
disable Protection setting.
4.7.3 NIBP Safety Valve
Test: Start test is for starting and Stop test is for
stopping the Safety Valve test.
Safety Valve Data:
For information on general items Pressure, Zero,
Protect handle, Calibr. prot., +15 V power, AD0 to
AD7 as well as Timeouts etc., see service data
descriptions in section “4.7 NIBP Module”.
Max. press and 2 s after stop show the measured
values at Safety Valve test.
Safety Valve Test Adult/Infant
Wrap an adult cuff around a pipe and connect the
cuff to the module. Highlight Start test and give the
ComWheel a push. The test ends automatically or
when Stop test (appears in place of Start test) is
pushed.
Max. press indicates the pressure at which the
safety valve opens and is normally 300 ±15 mmHg
for adult and 150 mmHg ±15 mmHg for infant.
2 s after stop indicates the pressure at 2 seconds
after the pump has stopped and is normally > 270 mmHg for adult and > 130 mmHg for infant. If the value is
less, check leakage by the active leak test.
