Start the CR pump

Press the CR pump motor start button (I). The motor will start, run up to full speed and the
'Drive motor running' checkbox on the main screen should have a
4.3.5

Run the Test Steps

Ensure that the Injector test cable appropriate for the type of injector under test is connected
as prompted on the screen after the Resistance test.
Pressing [OK] then puts the software into "testing" mode; on the main screen F1 changes to
'Stop Test'.
Manual tests
In manual tests the operator can click 'Next Step' and 'Apply Step' to go through the testplan
step by step.
When a test step is initiated the test stand is allowed a stabilisation time in the new test
conditions (if, for example, the rail pressure has been increased). This stabilisation time is
shown on the screen as the 'Wait for start' parameter. When the parameter has been counted
down to zero the test measurements for the step are taken.
During a test step several metering measurements are taken and the average of these
readings is the displayed result for the step. Each metering reading is an average of 10
injections. The 'Averaging readings' parameter on the screen shows a countdown of the
number of metering readings being taken. When the countdown reaches zero the average is
displayed and the next step in the testplan can be executed or the last step repeated by
selecting the relevant function key. When a test step is completed results are frozen unless
the "continuous reading" button is pressed.
During a manual test the operator may set a different injection speed (IPM) or pressure
demand etc. by typing directly into the box for that parameter on the screen and pressing 'F4'
twice to stop the step and then apply the new settings.
If the step fails for any reason (any of the parameters going outside tolerance) the 'Overall
Test Pass/Fail' will display a
to it. The operator may click 'Apply Step' to retry the current step or continue to the next step
by clicking 'Next Step'.
At the end of the manual test, after all steps have been run, the test stand stays in the running
conditions of the final step until the operator clicks 'Stop Test'.
Automatic tests
In automatic mode the test steps are run through automatically, with no operator intervention
(except the initial resistance test, where the operator has to connect cables to the injector). If
any step fails the results are still saved and the testplan continues.
At the end of an automatic test the testplan is stopped, the injections are stopped and a low
rail pressure is demanded.
The CR pump continues to run as the software has no control over this. The operator must
press the motor 'Stop' button to halt the CR pump.
