TSI Cal Check
Confirm the TSI calibration,
Used within temperature and altitude
range.
1) TSI Barometric Pressure: 69kPa <
reading < 102kPa (~10,000 ft. to -200 ft.),
2) TSI Temperature: 16C < reading < 32C,
3) TSI Calibration: current date does not
exceed due date.
• Return to main menu, select “Get TSI Flow Module”
information button and confirm operating conditions
• Swap-out to new module;
• Use notes to justify usage when out of spec.
Observations
Observation Resolution
Prior to servicing the device, ensure equipment and
technician safety.
• Use proper ESD precautions at all test stations when
opening the device.
• Follow proper safety precautions as noted in the
Service Manual
The tool is not compliant to FDA Part 11
• Print hard copy of each record, sign and maintain in
accordance to Quality System.
PC Setup
• If this is a new installation and if the drivers did not
register properly then the user will be unable to
read/write to the ventilator’s firmware.
• If connected to the Internet the Atmel driver may be
replaced by windows automatically to a non-
compatible open-sourced driver (BOSSA). Fix:
Reinstall the TCE software.
• With unit plugged in, verify “Load VCP” is unchecked
for both USB Serial Converter properties advanced
tab.

• Navigate to: device manager > universal serial bus controllers > USB serial converter
• Right click and choose properties, and select the advanced tab.
• Verify that Load VCP is unchecked.
• Repeat these steps for the 2nd USB serial converter.
TSI flow modules need to be calibrated on a yearly basis
• Contact TSI and calibrate module on an annual basis.
(See RCS manual)
The TSI may not maintain calibration for the year.
• Establish a monthly flow check.
• Properly store and protect the TSI module.
TSI Cables
• Inspect the TSI data cable to avoid data interruptions.
• TSI Data Cable
• O2 Cable
O2 Cell
• Calibrate when prompted
Faulty O2 Regulators
The O2 regulators need to be properly used to ensure proper flow.
• Oxygen Regulators may be damaged due to improper
use.
• Always close the tank and relieve pressure from both
sides of the regulator when not in use.
• Always open the tank slowly with the regulator in the
completely closed position (0 PSI). Turn the regulator
handle fully counter clockwise.
