7. The pipe volume (V) is needed for the calculation of the leak rate.
The ecom-EN2 offers two possibilities:
a. Type in pipe volume (V):
- Choose NO at the inquiry „Calculate Volume automatically?“.
- Type in pipe volume (V) with the instrument keyboard 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 cursor keys <right/left>.
- 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 the cursor keys < right/left >
and confirm 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 pr/- 10% during stabilization time, so the measurement
will start).
11. Once the measurement time is over, the result is displayed and
can be printed by pressing <Print>.
12. If the menu „Usage property“ is selected again, so the result
can be called up with <F4> (as long as the ecom-EN2 is on) or a
new measurement can be started with <F1>.
