Display layout
• MAX: Max Hold function engaged for the Air velocity function
• AVG: air averaging mode
• M/S, FPM,KPH,MPH, KNT: air velocity units of measure
•
: Low battery indicator
Power
• Press the power button (<.!>) to turn power on or off.
• Taking measurements, Hold the probe in the area to be tested.
• Allow adequate time for readings to stabilize.
• Pressing the MAXIAVG button toggles the display between maximum velocity and averaging
velocity.
• Hold down the MAXIAVG three second, you can enter the air velocity unit conversion mode loop.
Automatic Power OFF
To conserve battery life, the meter automatically turns off after 15 minutes.
Battery Replacement
When appears on the LCD [
], the 9V battery must be replaced.
