MAINTENANCE
1
While the CALIBRATION ERROR message is being displayed, press and hold the Alarm Silence button.
2
Continue to press the Alarm Silence button and then touch the yellow caution triangle on the screen. The system
will continue to load and then automatically enter the calibration screen.
3
Complete the calibration per the
CUFF and RESERVOIR CALIBRATION
section.
CAUTION:
If the full calibration is not completed or canceled in this mode, the system will enter a SYSTEM
FAILURE DETECTED alarm and the device will not be usable until the calibration is fully completed.
CALIBRATION CHECK
Below is a step-by-step procedure for checking the calibration of the cuff transducers. If the calibration is suspected
of being out of specifi cation, complete the calibration per the
CUFF and RESERVOIR CALIBRATION
section. This
section will allow the cuff transducers to be checked without changing or modifying the saved calibration.
1
If the system is not powered ON, press the Power ON/STANDBY button
and allow the system to fully start.
2
Connect the calibration hose supplied. Connect the hoses to the cuff transducer sense ports. The cuff transducer
ports are the right side port for each of the cuffs.
3
Using a calibrated meter and external pressure source, apply 50 mmHg of pressure to the cuff transducer sense
ports.
CAUTION:
During the calibration check the system will be detecting pressure in the Defl ated mode. This
will cause the system to alarm. This is normal and expected. The alarm silence button can be activated to
silence the alarm during the calibration check.
4
Once stabilized, verify that both the Main Cuff and Second Cuff pressure displays read 50±5 mmHg when
compared to the calibrated meter.
5
Increase the pressure in the external pressure source to 250 mmHg.
6
Once stabilized, verify that both the Main Cuff and Second Cuff pressure displays read 250±5 mmHg when
compared to the calibrated meter.
7
Increase the pressure in the external pressure source to 475 mmHg.
8
Once stabilized, verify that both the Main Cuff and Second Cuff pressure displays read 475±5 mmHg when
compared to the calibrated meter.
9
Increase the pressure in the external pressure source to 600 mmHg.
10
Once stabilized, verify that both the Main Cuff and Second Cuff pressure displays read 600±5 mmHg when
compared to the calibrated meter.
11
If any reading is off by more than ±5 mmHg, the entire unit must be recalibrated by following the
CUFF and
RESERVOIR CALIBRATION
section.
