12.2. MANUAL ADJUSTMENT WITH FIRMWARE UP TO V3.XX
PROCEDURE
1) Perform the following steps in a clean and draft-free place, with all instruments placed
on a stable base.
2) Remove the perforated lid.
3) Check the lower edge of the perforated lid visually
to ensure that there are no notches or unevenness.
This could lead to a leak between the perforated lid
and the base.
Damaged perforated lids must be replaced.
4) Remount the perforated lid.
5) Place the anemometer on the perforated lid of the air sampler.
6) Start the anemometer by pressing the ON/OFF
button.
The anemometer is in mass flow mode, showing
SLPM on the display.
7) Start up the air sampler by simultaneously pressing
the buttons YES and NO and keep them pressed
for approximately 5 seconds, until the K
3
menu is
displayed.
8) Modifying the K
3
value:
– Values 0 - 200 are possible.
– After reaching 200, the counter restarts at 0.
– Low K
3
value = High throughput
High K
3
value = Low throughput.
Press the YES button to increase the value until the desired value is reached.
or
Press the NO button to save the current value and continue.
9) 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
10) Iteration:
- Modify K
3
- Take anemometer reading
- Is the F
m
value firmly inside the range of 100 SLPM ±0.5 SLPM (99.5 - 100.5)?
o If No: Redo iteration.
o
If Yes: Press the NO button and continue.
