Introduction
BESANTEK BST-AFM06 CFM/CMM Thermo Anemometer with
InfraRed Thermometer measures Air Velocity, Air Flow (volume), Air
Temperature (with probe) and Surface Temperature (with the
InfraRed function). The large, easy-to-read backlit LCD includes
primary and secondary displays plus numerous status indicators.
The InfraRed feature includes a laser pointer for convenient
targeting. In addition, the meter can store 16 area setting dimension
for easy recall. Proper use of this meter will provide years of reliable
service.

2. Push the AREA button to scroll thru and select the desired
location. Once you have selected the desired memory
location enter your dimension
Use the ▲ (UP) button to change the flashing digit
Use the ◄ (LEFT) button to move the decimal
Use ► (RIGHT) button to select the other digits. After all of
the digits are entered, press and hold the AREA button (until
it beeps twice) to save the area into memory and return to

To select and use a previously stored dimension, press and hold the
AREA button until it beeps twice.
Press AREA to scroll thru the 8 memory locations. Press and hold
the AREA button until it beeps twice. to return to CFM or CMM
measuring mode.
Air Flow Measurements (Up to 20 Point averaging)
1. To enter 20 Point Averaging Mode, press and hold the AVG
button until it beeps twice. The AVG icon will be displayed.
2. Take a measurement and press the AVG button. A single
beep will sound and the HOLD icon will appear in the display.
3. The average reading will be displayed and number of readings
measured will appear in the upper right hand corner of the
display. After 5 seconds, the display will return to the current
reading. (IMPORTANT: Please note that the average
readings are only held for 5 seconds and cannot be recalled.)
4. Repeat steps 2 - 3 until all desired points have been
measured.
5. Press the AREA button to clear the multipoint averaging
memory.
6. To return to standard airflow measuring mode press and hold
AVG button until meter beeps twice.

Data Hold (Air Velocity/Air Flow)
1. While taking measurements, press the HOLD button to freeze
the air velocity/air flow reading for later viewing.
2. The HOLD indicator will appear in the bottom of the LCD
display.
3. Press HOLD again to return to normal operation.
MAX/MIN/AVG Record (Air Velocity/Air Flow)
This allows the user to record and view the highest (MAX), lowest
(MIN) and average (AVG) readings.
1. Press the button MAX/MIN button. The AVG indicator and
RECORD indicator along with the average reading will appear
on the LCD display and the meter will begin keeping track of
the MAX, MIN and Average values.
2. Press the MAX/MIN button again. The MAX indicator will
appear on the display and display the Max reading.
3. Press the MAX/MIN button again to view the minimum
reading. The MIN indicator along with the minimum reading
will appear on the LCD display and display the Min reading.
4. Press the MAX/MIN button again to display current readings.
NOTE: the meter will keep recording MAX/MIN/AVG
readings.
5. To clear and stop MAX/MIN/AVG recording and return to
normal operation, press the AREA button once when
displaying the current reading.

Temperature Units
1. Remove the meter’s rubber protective jacket and select the
desired temperature units using the °F/°C slide switch located
in the battery compartment.
2. Replace the protective jacket and connect the sensor to the
sensor input jack on top of the meter.
Data Hold (Air Temperature)
1. While taking measurements, press the PROBE
TEMPERATURE HOLD button to freeze the air temperature
reading.
2. The HOLD indicator will appear in the bottom of the LCD
display.
3. Press PROBE TEMPERATURE HOLD again to return to
normal operation.
Max/Min Record (Air Temperature)
This allows the user to record and view the highest (MAX), lowest
(MIN) air temperature readings.
1. Press the TEMPERATURE MAX/MIN button once. The MAX
indicator will appear on the display and the meter will begin
keeping track of the MAX/MIN air temperature values.
2. Press the button again to view the minimum reading. The MIN
indicator along with the minimum air temperature reading will
appear on the LCD display.
