Page 11: Section 2 - Switch Functions
SECTION 2 – SWITCH FUNCTIONS Pressing the ON/OFF key switches the instrument ON. Hold down the key for 2 seconds to switch the unit OFF. The unit will automatically power off after 30 minutes without any key presses. To disable auto power-off, hold down the power button during turn-on. - Page 12 Press the FPM/MPS key to switch the measurement units from FPM (feet per minute, 1 FPM resolution) to MPS (meters per second, 0.01 MPS resolution). Either FPM or MPS will be displayed on the LCD. Press the SAMPLE RATE key to change the measurement averaging rate (“sample rate”) of the unit: ...
- Page 13 Press the HOLD/RESET key to freeze the current reading on the display. HOLD is displayed on the LCD and the reading is held. Press the HOLD/RESET key a second time to clear this mode and return the unit to normal operation. Press the HOLD/RESET key while in MIN/MAX mode to display BOTH the minimum and maximum airspeed reading since the MAX/MIN key was pressed.

Page 18: Section 3 - Operational Notes
SECTION 3 – OPERATIONAL NOTES Caution: Do not attempt to measure flow from a duct that is smaller than the diameter of the probe head that you are using. This will cause a false reading. Follow the minimum duct cross-section guidelines as detailed below: AP275 probe (2.75 inch): Minimum duct width of 2.7 inches (69 cm) Minimum duct height of 2.7 inches (69 cm) -

Page 20: Appendix C - Airflow Volume Calculations
APPENDIX C – AIRFLOW VOLUME CALCULATIONS To calculate cubic feet per minute (CFM) from a measured air velocity (FPM), you need the calculated cross-sectional area of the air flow stream: Volume Flow (CFM) = Velocity (FPM) X Area (sq ft). In a rectangular duct this cross sectional area equals the Width times the Height. -
