4.3 Test Setup and Method
The basic parameters that will establish the condition of a CR injector are:
Spray Pattern (checked on Testmaster)
Delivery vs. pressure vs. pulse width
Backleak flow (dynamic and static)
Response Time
Example testplans are provided for each manufacturer.
characteristics for that manufacturer's injector and typical demand settings for various conditions.
They do not contain expected results values as these will be specific to each injector part number.
These example testplans can be used as a basis for creating dedicated testplans for specific
injectors.
The following instructions assume that the basic kit has been installed (see Section 2).
4.3.1 Fit the Surrogate Pump
Mount the surrogate pump (either a Bosch CP1 with PCV or a Siemens Pump), and connect to the
Pump Control Unit (refer to HF1130 manual and associated bulletins).
NOTE
If using a Siemens pump connect the cable the opposite way around to normal i.e. fit
the connector labelled "FCV" to the pressure control valve, and fit the connector labelled
"PCV" to the flow control valve. Additionally, set the "Channel B Current" to 2A (this
applies 2A to the FCV so that it will deliver maximum flow).
4.3.2 Load a Testplan
When you first enter the CR Injector Test screen it will be mainly blank (as in Figure 4.1); you must
load a testplan to start testing.
To load the example testplan for the relevant injector manufacturer, first press F2 to access the
Testplan Menu (shown below), then select the Manufacturer and Part Number required, then click
[Load Testplan], then [OK].

Used to apply an open loop current demand to the second channel of the
pump control box (only required when using a Siemens pump as the
surrogate – see Section 4.3.1, otherwise set to 0 A).
Returns to the Main Menu
Opens the Testplan Menu. From here you can Save changes to the
current testplan, create a New testplan, load a different testplan, and edit
the Testplan/Injector details. See Section 4.5.
Not used.
Start a test (with possibility to save results). See Section 4.3.5.
Opens a dialog where you can select previously saved results to view.
See Section 4.7.
Metering mode temperature compensation (function key not enabled,
this parameter is set in the testplan).
Print (only enabled in Results View – see Section 4.6)
Opens the standard Limits/Units screen.
Toggles the metering mode between Overcheck and Calibrate. Calibrate
is the more accurate mode and should be used for taking results.
Opens the standard Metering Limits dialog.
