975 AirMeter Test Tool • Introduction W Warning Read “Safety Information” before using the 975 AirMeter Test Tool. The Fluke 975 AirMeter Test Tool (“the Meter”) is a hand-held, five-sensor indoor air quality diagnostic instrument. It measures, calculates, and displays: • Temperature, dew point, and wet bulb all measured in Celsius (°C) or Fahrenheit (°F). • Relative humidity (%RH). • Carbon monoxide (CO) levels measured in ppm. • Carbon dioxide (CO2) levels measured in ppm.

For Lithium battery replacement, the Meter must be sent to Fluke.
975 Users Manual Startup and Self Test To turn the Meter on, press and hold for a few seconds and wait for the flashing red LED on the left side of the display. Press for 2 seconds to turn the Meter OFF.
AirMeterTM Test Tool Using the Meter Table 4. Startup Failure Messages Failure Message Action Temperature Sensor: FAIL Have the Meter serviced. The Meter may still be used. Wet bulb, Dew point, Temperature and Humidity functions are unavailable. CO or CO2 readings are inaccurate. Have the Meter serviced. The Meter may still be used. CO or CO2 functions are unavailable. If either sensor fails, then calculations are incomplete. Have the Meter serviced. The Meter has internal failures.
975 Users Manual Multi-Language Interface The Setup Menu The Meter’s display supports five languages: English, French, German, Portuguese, and Spanish. Use the Setup menu to change the display language. See “The Setup Menu”.
AirMeterTM Test Tool Taking Measurements 4. 5. 6. Press and as necessary to change the item values. Hold down or to increase the rate of change. Press [Select], or in some cases [Done], to store the changes. Press for 2 seconds to exit the Setup menu. All changes are stored.
975 Users Manual variables are known, the Meter computes the % outside air. % Outside Air (Temperature) To obtain % of outside air using temperature: 1. Place the Meter sensor perpendicular to the air stream being measured. 2. Press .The Meter switches to % outside air measuring mode and offers choices of [CO2] or [Temp]. 3. Press [Temp]. The Meter measures and displays the return air temperature. 4. Press [Capture] to store the return air reading.
AirMeterTM Test Tool Taking Measurements 7. 8. use [UP] and [DOWN] to change the CO2 content reading to the desired number. Press [ENTER]. Once the outside air CO2 content is entered, return air, mixed air, and outside air CO2 content are shown in parts per million (ppm). Press [Calculate] to show the % outside air or press [Back] to change any of the measurements. Press [Done] to end the % outside air measurement.
975 Users Manual 5. 6. 7. Press [Capture] to capture the standard velocity reading, [Actual] to change to the actual velocity menu, or [Back] to return to the velocity menu. Note In this case, pressing [Capture] does not create a single point data log, it simply freezes the display reading. If the standard reading was captured, press [Actual] to view the actual air velocity reading. Press [Done] to return to the velocity menu.
AirMeterTM Test Tool Min Max Avg Min Max Avg Saving Single-Point Data The Min Max mode stores minimum (MIN) and maximum (MAX) input values. When the input drops below the stored minimum value or above the stored maximum value, the Meter beeps and stores the new value. Min Max mode also calculates an average (AVG) of all readings taken since the mode was activated. Min Max mode works with Temperature, CO, CO2, Relative Humidity, Dew Point, Wet Bulb, and Air Velocity. To use Min Max mode, press .
975 Users Manual 1. 2. 3. 4. To save single-point data: Take a desired measurement. Press . The Log/Save menu appears on the display. The measurement that was displayed when was pressed is the measurement that will be saved. Press [Save Data]. The Meter shows “Saving…”. The data is saved and the Meter returns to the screen where the data originally was taken. Note Press [Cancel] to cancel data saving and to exit the Log/Save menu. All other keys are inoperative while logging.
AirMeterTM Test Tool Data Logging Once the desired parameters have been entered, the display shows the selected duration time, sampling interval, and the available memory %. 6. The Meter requests user confirmation before starting a logging session: • Press [Yes] to confirm the settings and begin logging. • Press [Adjust] to change logging parameters. • Press [Cancel] to return to exit the logging mode. The Meter logs the sessions until stopped or the logging interval has expired.
975 Users Manual Recalling or Erasing Logged Data Use the Recall function to retrieve or erase the single point or continuous logging session records. To view single points of data: 1. Press to show the Recall menu. 2. Press [Single Point]. Detailed sessions appear on the display starting with the most recent sample. 3. Press [Next] or [Previous] to move the cursor to the previous or next detailed sample. 4. If the velocity probe is attached, press to access the velocity section of the sample.
AirMeterTM Test Tool Transferring Data to a Personal Computer Transferring Data to a Personal Computer 6. Data that is collected and stored in the Meter’s memory can be downloaded to a personal computer (PC) using the included FlukeView Forms Documenting Software and USB cable. See Figure 3 to locate the USB port on the Meter. To install the software, see the “FlukeView Forms Installation Guide” that comes with the software. 7.
975 Users Manual Calibration Calibration due dates are tracked using the Meter’s clock and stored in non-volatile memory. Due dates can be configured by the user from one to 365 days. When the Meter reaches its calibration due date, it alerts the user but will continue to operate. The Meter’s CO and CO2 sensors can be calibrated by the user or returned to Fluke for service. See “Contacting Fluke”. The recommended calibration interval is 1 month for CO and 1 year for CO2.
AirMeterTM Test Tool Calibration 5. When sensor zero is complete, remove the nitrogen and press [OK] or [Cancel] to exit calibration. The Meter displays: Apply CO Calgas concentration… 3. 4. 6. Enter the concentration amount using [DOWN] and [UP] to change the entry and [ENTER] to store it. 5. 7. Apply the calibration gas mixture of CO and CO2. Press [OK] or [Cancel] to exit calibration. 6. 8. When finished, remove gas and press [OK]. Enter the time to next calibration date.
975 Users Manual 3. 4. 22 Press [CO2]. Specify one-point or two-point calibration methods. The one-point method uses CAL gas only. The twopoint method uses CAL gas and also Neutral gas (Nitrogen). If one-point is chosen: a. Use [DOWN] and [UP] to choose the CAL gas concentration. b. Press [ENTER] to enter the concentration. c. Apply the CAL gas and press [OK], press [SKIP] to exit calibration mode. The Meter will now calibrate the CO2 sensor for 2 minutes.
