Ecom EN2 Operating Instructions Manual page 33

The gas losses measurement is to be
performed with the instrument´s sampling
probe in the gas core stream after menu
call up (see chapter 8.1.). Once the
measurement
<Memory> (disk symbol) the conversion
of the measurement results in negative
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 sensor) is
determined and the percentual loss is
calculated. Once the menu point is called
up, the boiler performance must be inputed.
To easy the measurement width, depth and
height of the boiler can also be entered
(dimensions will be memorized for surface
calculation). 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 inputed, press <F1> (Start) to activate the
measurement recording. Here the dimensions for all surfaces must be
inputed.
