Draught Measurement - Ecom j2kn pro Operating Instructions Manual

8.5. Draught measurement

A trend indication for the draught conditions in the exhaust channel
can already be determined during the gas analysis. Nevertheless the
value for the chimney draught will not be stored together with the gas
values while pressing the key <Memory>.
Indeed the difference pressure sensor tends to drifts because of its
sensibility and, for an exact measurement it is consequently advised
to re-calibrate the sensor immediately before sampling and docu-
menting the value.
Access the menu while selecting the
sub-menu "Pressure". The current
value is displayed as well as the instruc-
tion to adjust the zero point of the sen-
sor. Release hereto the draught hose
from the instrument for a short moment
and press <F4>. The sensor is herewith
re-calibrated.
Fix the draught hose again. The display
shows the exact measurement value
which can be stored while pressing
<Memory> and added to the previous
results in the intermediate memory. The
stored value is shown on the display.
Press <ESC> to quit the differential
pressure measurement menu.
