Operation

The vane assembly must be rotating before you move on/off lever to the on position. Failure to do so could cause damage to the internal mechanism. 

You will need to apply your correction factor which will be affixed to the case of the unit.

 We recommend taking several readings to determine the most accurate airflow testing.

 If the area is large, you may need to use a traverse method of testing to get the most accurate readings.

1. Zero out hands by moving reset lever downward. 

(If Applicable

Luminous Charge=15s)

2. Once the unit is placed directly into the flow of air, allow the unit to start spinning in the off mode until fully at speed.

3. Once the unit has reached full speed, you can now move the on/off lever to the right and begin taking your measurement.

4. The measurement is taken for one minute, and then you must move lever to the off position, the readings will remain on dial until you reset back to zero
