16) Change the blower Speed until the flow on the ane-
mometer is stable and close to the Adjust-
ment flow.
The current Adjustment flow is displayed in the
Mean flow box.
Pressing aborts the process.
Note
If a reference value must be recorded for documentation purposes, go to the
Flow Adjustment Data tab in the PC Software and use the ADC at target flow
value after the adjustment.
Annex A.2.1 provides additional background information.
17) Anemometer reading:
– Allow the anemometer 40 seconds to settle prior taking readings.
– Take 3 consecutive readings from the anemometer.
– Note these 3 flow values: F
1
, F
2
, F
3
– Calculate the Mean flow value: F
m
= (F
1
+ F
2
+ F
3
)/3
18) Iteration:
- Modify blower Speed
- Take anemometer reading
- Is the F
m
value firmly inside the range of Adjustment flow ±0.5 SLPM?
o If No: Redo iteration.
o
If Yes: Press the button and continue.
Example
Adj. Point
❶
Adj. flow 100.0 SLPM
Tolerance ±0.5 SLPM
Adj. flow range 99.5 - 100.5 SLPM
19) Enter the last calculated Mean flow value F
m
by
modifying the displayed value.
Press the button to save the value and to pro-
ceed.
Pressing aborts the process.
20) Press the Yes button to accept the adjustment and
store the values in the air sampler.
Pressing No aborts the process.
21) If used, remove the MAS-100 Family Calibration Disk or the Petri dish.
22) End of process.
