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>).
