Checking the NBP Calibration
The NBP parameter box gives you access to the NBP Calibration
mode. These checks must be performed in Adult Mode only.
STEPS: NBP Calibration
1. Click on the NBP parameter box.
2. Click on
Calibration Mode.
3. Select
ON and click the knob.
4. Replace the cuff with a mercury manometer.
5. Pump the manometer until the mercury column reads 260
mmHg. Verify the displayed value on the monitor.
6. Release the pressure and read the pressure value at three dif-
ferent points on the mercury column: the displayed values on
the monitor should be within ±3 mmHg of the manometer
readings.
7. Close the release valve on the bulb and pump the manometer
until the overpressure release valve opens. This should hap-
pen at 300 mmHg ±30 mmHg and the mercury column
should fall rapidly to zero. If the release valve does not open
or if it opens at a value lower than 300 mmHg ±30 mmHg,
the overpressure system may be faulty. Remove the monitor
from service and contact DrägerService.
NOTE: If the monitor is left in the calibration mode for more than
128 seconds after a first measurement has been started, an NBP
Fault condition is reported. This message does not indicate a hard-
ware failure but the activation of the safety timer of the monitor. To
clear the message, turn the monitor off, then on again.
