Uniform delivery
The "uniform delivery" test step type, also known as
the "visual check", is used to obtain a quick assessment
of a pump (see also section 9.4 "Uniform delivery" in
the program description 1 689 979 859). It checks for
uniform pressure generation in the pump in the lower
pressure range and with the IMV approx. 2/3 closed.
The pressure increase in the high pressure rail over
3 pump revolutions is measured and displayed. Each
pressure increase must be uniform. If it is not, e.g. one
pressure increase is significantly flatter than the others,
this could be due to a defective pump piston. In such
cases, the test can be aborted and the pump repaired.
�.2.2
Zero-delivery
The "Zero-delivery" test step type tests the IMV in the
Delphi pump for leaks (see also section 9.5 "Zero-de-
livery" in the program description 1 689 979 859). The
IMV is energized with the maximum permitted current
and the high pressure rail in the CRS 845 test set is
completely closed. The IMV closes the fuel supply into
the pump. The pump then no longer delivers any fuel
into the high pressure rail. If the IMV is defective, test
oil continues to be delivered into the pump. This results
in an increase in the rail pressure.

Procedure:
1. Start the EPS945 system software.
?
2. After successful initialization, call up the "Compo-
nent selection" dialog box by pressing <F�2>.
3. Press <F2> and select the Search for component op-
tion to call up the local component database.
4. Select the Delphi Sample Rotation R sample test
sequence and call it up by pressing <F�2>.

Producing the test sequence
The preset actuation parameters for com-
ponents made by manufacturers other than
Robert Bosch GmbH are based on internal
investigations as they have not been com-
municated to Robert Bosch GmbH by the
manufacturer. They do not therefore corre-
spond to the relevant manufacturer's factory
specifications and have not been adjusted
to do so. Robert Bosch GmbH therefore pro-
vides no guarantee that the preset actuation
parameters for non-Bosch components are
correct. The user is responsible for ensuring
that non-Bosch components are properly
tested. Robert Bosch GmbH accepts no li-
ability for damage, expense or other con-
sequences arising as a result of incorrect
setting of the actuation parameters.
