Ecom EN2 Operating Instructions Manual page 34

Press <F3> (Start + ->) to start the real
measurement. Proceed as follows:
- select surface (boiler side) to be measured
with <F1> or <F2>
- position surface sensor
- record temperature difference with
<Memory> - up to 10 values can be
recorded per surface out of which a mean
value will be calculated automatically
- if need be, cancel measurements
with <F4>
- repeat this procedure for each surface
Once all surface temperatures have been determined, quit the menu with
<ESC>. The surface losses get automatically calculated. The value
conversion in negative points is available in the menu point „Results".
The ventilation loss measurement is
performed by a flow probe 30 sec. after
burner switch-off. This measurement can
be performed at the earliest 5 min. after
instrument´s switch-on as the pressure
sensor requires this period of time for
stabilisation. Once the menu is called up,
the values for air pressure, external
temperature, boiler performance and
exhaust gas pipe diameter must be
inputed . Hereto proceed as follows:
- open respective window with <Enter>
- input figures using numerical function
of keys
- confirm input with <Enter>
or:
- adjust values using the cursor keys <Right/Left>
