16.
Use the ComWheel to increase the AIR flow to read 30.0 L/min on the
“AIR flow” “Rated” The units in the service menu change from Digits to
L/Min.
17.
Verify that the external flow meter device reads 30
±
1.5L/Min.
18.
If not readjust the “Gain” for the AIR flow sensor with R 313 on the main
board to read 30
±
1.5 L/Min.
19.
Use the ComWheel to decrease the AIR flow to read 0 L/min.
20.
Check the “AIR flow” “Actual” to be at the “Rated” value
±
50 digits .
21.
If not, readjust the “Zero” for the AIR flow sensor with R 316 on the main
board to read the “rated” value
±
10 digits.
22.
Use the ComWheel to increase the AIR flow to read 10.0 L/min on the
“AIR flow” “Rated” The units in the service menu change from Digits to
L/Min”.
23.
Verify that the external
flow meter device reads
10
±
0.5 L/Min.
24.
If not , go back to step
16. Change setting for 30 l/min within the tolerance in the desired
direction to match the 10
±
0.5 L/Min.
25.
Use the ComWheel to increase the AIR flow to read 60.0 L/min on the
“AIR flow” “Rated”.
26.
Verify that the external flow meter
device reads 60
±
3.0 L/Min.
27.
If not, go back to step 16. Change
setting for 30 l/min within the
tolerance in the desired direction
to match the 60
±
3.0 L/Min.
28.
If the AIR flow cannot be
calibrated within the three flow
specifications, check AIR gas
filter.
Best results for linearity match with all three test flows are received when initially
the “Gain” is adjusted at 30 l/min value of step 16. to read 29.8 L/min on the
external flow meter device.
