Ecom EN2 Operating Instructions Manual page 39

The gas losses measurement is to be
performed with the instrument´s sam-
pling probe in the gas core stream after
menu call up (see chapter 8.1.). Once
the measurement is recorded with
<Memory> (disk symbol) the conver-
sion of the measurement results in neg-
ative points is available under the menu
point „Results".
The surface losses measurement is
performed by a temperature sensor
specific for surfaces. The temperature
difference between boiler surface and
room temperature (air temperature sen-
sor) is determined and the percentage
loss is calculated. Once the menu point
is called up, the boiler performance
must be inputted. To easy the meas-
urement width, depth and height of the
boiler can also be entered (dimensions
will be memorized for surface calcula-
tion). Please proceed as follows:
- activate respective input window
with <Enter>
- inputs values using the keys numerical
function
- confirm input with <Enter>
or:
- adjust values using the cursor
keys <Right/Left>
If no boiler dimensions are inputted,
press <F1> (Start) to activate the
measurement recording. Here the di-
mensions for all surfaces must be in-
putted.
