Ecom EN2 Operating Instructions Manual page 40

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 stabilization. Once the menu is
called up, the values for air pressure,
external temperature,
mance and exhaust gas pipe diameter
must be inputted. 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>
