ecom-B
7. The pipe volume
(V)
is needed for the calculation of the leak rate.
The ecom-B offers two possibilities:
a. Type in pipe volume
(V)
:
- Choose
“No”
at the inquiry
“Calculate Volume automatically ?“
(switching from
“No“
to
“Yes“
with cursor keys
<Up/Down>
).
- Adjust pipe volume
(V)
with cursor keys
<Up/Down>
and confirm
with
<Enter>
.
b. Calculate pipe volume automatically
(V)
:
- Choose
YES
at the inquiry „Calculate Volume automatically ?“.
- Connect the squirt or soot pump as described before.
- Open ball valve and wait until the pressure is stabilized.
- Choose squirt or soot pump with the key
<CAL.>
.
- Start volume calculation with
<Enter>
.
- Infer the test volume with squirt or soot pump. The decrease of
pressure must be min. 2 hPa (otherwise operate squirt or soot pump
several times).
- Close ball valve and confirm with
<Enter>
.
- Choose number of strokes with cursor keys
<Up/Down>
and con-
firm with
<Enter>
.
8. Create the pre-adjusted test pressure with the air pump (the unit
beeps as soon as the pressure level is achieved).
9. Interrupt the connection to the air pump (switch-off the ball valve).
10. Wait for stabilization time (if the pressure remains in the range
“test pressure +/- 10%”
during stabilization time, so the measure-
ment will start).
11. Once the measurement time is over, the result is displayed and
can be printed (IR printer required) by pressing
<Print>
.
12. If the menu
“Usage property“
is selected again, so the result
can be called up with
“No” / <Enter>
(as long as the ecom-B is on)
or a new measurement can be started with
“Yes” / <Enter>
(switch-
ing from
“No“
to
“Yes“
with cursor keys
<Up/Down>
).
