6. Select the channel to be calibrated in the menu and select the pressure value to which the IBP is to be
adjusted.
7. Inflate to make the mercury bar rise to the setup pressure value.
8. Adjust repeatedly until the value in the menu is equal to the pressure value shown by the mercury
calibration.
9. Press the Start button, the device will begin calibrating.
10. Wait for the calibrated result. You should take corresponding measures based on the prompt information.
11. After calibration, disassemble the blood pressure tubing and the attached 3-way valve.
If the following messages prompt up, refer to relevant instructions (take channel-1 for instance):
• "SENSOR OFF, FALL"
Make sure that sensor is not off, then proceed calibration.
• "IN DEMO, FAIL"
Make sure that the monitor is not in DEMO mode. Contact service technician if necessary.
• "PRESSURE OVER RANGE, FAIL"
Make sure that you have selected transducer value in IBP CAL, then proceed calibration.
Changing the Label

Figure 15-8 IBP SCALE ADJUST Menu
The waveform and corresponding scale appears in the IBP Waveform Area with 3 dotted lines representing
High Limit Scale, Reference Scale, and Low Limit Scale from the top to the bottom. Values of the three
scales can be user-set according to the instruction given below.
• IBP label: selectable from ART, PA, CVP, RAP, LAP, ICP, P1, P2;
• HI: IBP value of High Limit scale, the range is the measuring range of the current pressure.
Note
• The HI value must be higher than the LO value.
LO: IBP value of Low Limit scale, the range is the measuring range of the current pressure.
• The LO value must be lower than the HI value.
VAL: IBP value of Reference scale (between HI and LO).
• When change HI scale, Low scale or Reference scale of IBP waveform and the corresponding IBP
waveforms are displayed under the menu window, the waveform will come penetratingly through the menu
window for observing.
15.5 Alarm Information and Prompts
Alarm Messages
Among physiological alarms, those belonging to the type that the parameter has exceeded the limits may
activate the recorder to automatically output the parameters and related measured waveforms when the
alarms occur on the condition that the alarm record switch in the related menu is On.
Tables below describe the possible physiological alarms, technical alarms and prompt messages occurring
during IBP measurement.
