Pre-Test Checks and Instrument Setup

Power and Warmup
The Certifier™ Pro Flow Analyzer can be operated through AC power or on battery power. With AC power applied, the battery will automatically recharge. Upon startup, allow 1 minute for the Certifier™ Flow Analyzer’s flow sensor and pressure transducers to warm up.
Instrument Calibration
Confirm that the calibration date for the Certifier™ Pro Flow Analyzer is valid. TSI® recommends an annual calibration to ensure the most accurate flow, pressure, and temperature measurements.
Zero Low / High Pressure
Disconnect any pressure tubing from the low and high pressure ports on the front side of the instrument to expose the sensors to ambient air. Press the zero icon on the Certifier Pro display to access the Zero Pressure Sensors screen and perform the zeroing.
Oxygen Sensor Calibration
Calibrate the oxygen sensor daily, following an altitude change, or after replacement. Navigate to the Settings menu and select Oxygen Sensor. Follow the directions on screen to calibrate with air or oxygen.
Connect Inlet Filter
Connect filter to the breathing circuit upstream of the Certifier Flow Analyzer. TSI® supplies inlet filters for the high and low flow channels and recommends that filtration be used at all times during operation.
Connect Low Pressure Measurement
Attach the airway pressure fitting (1) to the breathing circuit. Cut a length of silicon tubing (2), connect one end of the tubing to the barb on the airway pressure fitting, and connect the other end of the tubing to the (+) low pressure port located at the front of the instrument.

Test Circuit for Bi-directional Flow

Touchscreen Operation

The Certifier™ Pro instrument utilizes a 5-inch capacitive touchscreen display. The display interface is designed to be operated using your fingers, press lightly on the display for optimum touchscreen operation. A capacitive- touch stylus can be used as an alternative to operating with finger presses.
Operate the Certifier™ Pro Flow Analyzer by touching any on-screen element that you would like to change. Up to 18 measurement parameters can be displayed on screen at one time, and the display will automatically adjust the font size and positioning based on the number of selected measurements.

Breath Triggers
Triggers are used to detect the start of the inspiratory and expiratory breath cycles. Triggers can be based on the flow rate, pressure, or driven from a TTL voltage signal. The Certifier™ Pro Flow Analyzer can automatically detect the breath using the flow rate, or you can manually set your own start and end trigger values using the flow rate or low pressure. In most circumstances, it is recommended to use the Auto Trigger setting.

Breath Averaging
The number of breaths specifies the maximum number of breaths over which to average breath parameter measurements. The averaging time sets the rate at which real-time values are averaged and updated on the Certifier™ Pro display. Real-time values include measurements for flow rate, low pressure, high pressure, absolute pressure, oxygen concentration (if connected), and temperature.

Certifier™ Flow Analyzer Configurations
A Certifier™ Flow Analyzer configuration is a saved collection of settings for the measurements, units, gas type and conditions, triggering, and graphing that you have selected. Any Certifier™ setup can be saved as a configuration and later recalled. Configurations can be saved for testing various types of equipment or to optimize test setups to conform with organizational standards or personal preference.
Configurations are stored in the internal memory of the 4090 Certifier Pro instrument and can be exported to a USB mass storage drive via either USB-A port. Exported configurations can be sent as email attachments and they can be imported onto different Certifier Pro or Certifier Plus instruments.
Data Acquisition
The Certifier Pro Flow Analyzer is capable of logging measurement data and capturing screenshots. Data can be saved from either the Parameter or Graph screen, and files are saved to the internal memory of the Certifier Pro Flow Analyzer.
Snapshots save a screenshot image as well as the data currently displayed on screen. Continuous logging captures data for all measurements selected on screen at sample rate of 1 sec to 10 mins and test length from 15 secs to up to 5 days. Waveform logging records raw sensor data at a rate of 1000 Hz for a length of 15 to 60 seconds.
Data Export
Saved screenshots and data log files can be exported from either of the two USB-A ports located on the back of the 4090 Certifier Pro Flow Analyzer. Snapshots are exported as .png image files and data is exported as .csv files. The delimiter for data export can be set as comma, pipe, semicolon, or tab delimited. You can select the Export Delimiter in the General Settings page of the Settings menu option.
