5. ADJUSTMENT AND CALIBRATION OF
MAS-100 NT AND MAS-100 NT EX WITH
PC SOFTWARE
Hazard of wrong results
The anemometer is a high-precision measurement instrument sensitive to
draft currents and air turbulences. The anemometer and the air sampler shall
not be exposed to direct sunlight during calibration.
The measurement should take place in a room free from draft currents and
turbulences, including people walking by.
It is recommended to remain calmly seated in front of the anemometer during
this procedure to avoid air turbulences.
Hazard of wrong results
An air sampler must be re-adjusted and calibrated if the measured air flow is
out of the allowed tolerance band, or if the calibration expires.
Hazard of failed adjustment and/or calibration
If the message Sensor calibration failed or Sensor offset out of tolerance ap-
pears, press Exit and reselect Manual Adjustment.
This message may appear due to the extreme sensitivity of the anemometer
during the self-check procedures.
Hazard of failed adjustment and/or calibration
Never perform a manual 1-point adjustment with default settings loaded or af-
ter repairs. In such cases a manual 3-point or an automatic adjustment must
to be done, as described in chapter 5.3, chapter 5.4 or chapter 5.5 respec-
tively.
Note
MBV AG recommends to perform a calibration after every adjustment.
Note
MBV AG recommends to use automated procedures for adjustment and cali-
bration whenever available.
