Setup and Pre-Test Checks
Power and Warmup
The Certifier™ Plus 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.
Connect/Disconnect Flow Modules
Connect high flow or low flow modules to either port (A or B) located at the top of the Certifier™ Plus Interface Module. Flow modules may be connected or removed at any time. The interface display will reboot the application automatically upon a change in connected flow modules.
Connect Inlet Filter
TSI® Certifier™ Flow Analyzers measure utilizing an exposed thermal flow sensor that is highly sensitive to foreign matter and particles within the gas flow. TSI® supplies inlet filters for both the high flow and low flow modules and recommends that an inlet filter be used at all times when operating the Certifier™ instrument.
Pre-Test Checks
- Calibration Date: Confirm that the calibration date for the Certifier™ Plus flow module is valid. TSI® recommends an annual calibration to ensure the most accurate flow, pressure, and temperature measurements.
- Low/High Pressure: Disconnect any pressure tubing from the low and high pressure ports on the 4081 High Flow Module to expose the sensors to ambient air. Press the zero icon on the Certifier Plus display to access the Zero Pressure Sensors screen and perform the zeroing.
- Flow Module Self-Check: Connect two of the same model Flow Modules inline to compare real-time measurements against each other.
Connect Low Pressure Measurement
Low pressure is available on the 4081 High Flow Module only. Connect the airway pressure fitting with screen (1) to the outlet of the flow module. Cut a length of tubing (2) and connect it from the airway pressure fitting barb to the (+) port on the flow module.
Connect Oxygen Sensor
The oxygen sensor can be connected to High Flow modules only. You can connect or disconnect an oxygen sensor at any time without interrupting the operation of the instrument. Oxygen sensors should be field calibrated daily when in use and following a change in altitude.
To connect an oxygen sensor, unpackage the O2 cell and screw it into the airway coupling. Connect the airway coupling to the outlet of the flow module and insert one end of the sensor cable into the top of the O2 sensor cell. Connect the other end of the sensor cable to the input labeled “O2 Sensor” located on the top of the high flow module.
Test Circuit for Bi-directional Flow
NOTICE
If using a test lung with a built-in restrictor, place the airway pressure fitting with less than 15 cm length of the 22 mm tubing between the restrictor and the flow module. If this is not done, the flow direction sensor may not work properly.
Touchscreen Operation
The Certifier™ Plus Interface Module 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. TSI® offers a capacitive-touch stylus (TSI® P/N 130370) that can be used as an alternative to finger presses.
Operate the Certifier™ 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™ Plus 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.
When more than one flow module is connected, the breath triggering is controlled from the flow module connected to channel A of the Certifier™ Plus Interface Module. The flow module that is controlling the breath triggers will be indicated on the screen with an asterisk (*) displayed in the module card before the serial number.
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™ Plus 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™ Flow Analyzer 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.
Up to 20 different user configurations can be stored in the internal memory of the 4089 Certifier™ Plus Interface Module and can be exported from either USB-A port on the 4089 to a USB mass storage device. Exported user configurations can then be imported onto other model 4089 Certifier™ Plus or model 4090 Certifier™ Pro instruments. Exported configurations can also be sent as email attachments.
Data Acquisition
The Certifier Plus 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 Plus Interface Module.
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 top side of the 4089 Certifier Interface Module. 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.
