Thermo-Anemometer / English

1. Introduction

The CFM/CMM Thermo Anemometer instrument measures Air Velocity, Air Flow (volume) and 
Temperature. The large, easy-to-read backlit LCD includes primary and secondary displays 
plus numerous status indicators. The meter is shipped fully tested and calibrated and with 
proper use will provide years of reliable service.

2.Keypad

• POWER   Press to turn the meter ON or OFF
• MAX/MIN Used to record and store the highest, lowest and average airflow or velocity 
readings.
• UNITS Press to select the mode of operation. In FLOW mode, the meter displays air volume.
   In VELOCITY mode, the meter displays air speed.
• HOLD Press to freeze the displayed reading. Press again to unlock display. This button also 
functions as the
• AREA Press and hold to manually enter the area of a duct in CFM or CMM mode. In AREA

•   Press to turn the backlight on/off
• °C /°F (Temperature) Press to freeze the displayed temperature reading. Press again to 
unlock the display. Press and hold for 3 seconds to switch between °C and °F. Meter will 
beep twice to indicate change.
