Performance Verification
Real-time Clock
Calibration
The BiPAP Focus will record and track several different parameters (e.g.
patient pressures, apnea events, when and how the device is used, error codes,
etc.). To do this in a logical manner and for a technician or therapist to know
exactly when a certain event has occurred, the BiPAP Focus runs and records
events in real-time. This time is checked and compared to your computers
time when running the calibration software. If the time does not match, the
calibration will fail. Therefore, you must perform the real-time clock calibration
before you proceed with the BiPAP Focus calibration.
Equipment Required
• BiPAP Focus Communications Cable Kit (P/N 1030010)
• Utility Software
Procedure
1. Ensure AC power is connected to the BiPAP Focus.
2. Remove the bacteria filter from the ventilator if it is connected.
3. Start the ventilator in Normal mode. Be sure the vent is in S/T mode.
4. Connect the universal serial bus (USB) cable between the service PC
and ventilator.
5. Connect the female end of the serial communications cable to the
service PC. Then connect the male end labeled Software/Rasp to the
ventilator.
6. Open the Service Center Tools and select “Read Serial Number &
Model number”. Write down the serial number and the model number
for use later on during the calibration.
7. Open the Service Center Tools and select “Real-time Clock
Calibration”.
8. Click the red “Set Clock/Verify Clock” button in the upper left-hand
corner to begin calibration (the button will turn green).
NOTE: Do not connect the USB cable through a hub or docking station. Using
an intermediate connection causes communication errors.
