5.3.5 Backleak Audit With Magmah v9.01 onwards (If optional backleak measurement unit is
fitted)
Refer to figure 5.5
Specific note for pressurised backleak units:
Before starting an audit the following should be disconnected:
a) the extraction tube hydraulic connection (5
degree push-fit elbow)
These must be re-connected after the audit.
A single (CRi 1-line) or set of four (CRi 4-line) good injector(s) should be used for the
backleak unit audit. The purpose of the audit is to check the following three features of the
backleak unit:
- measurement line transducer offsets (step 2)
measurement line 'max fill' calibration values (step 4)
-
- measurement system leakage (step 5)
If the audit indicates a problem in any of these areas, please contact Hartridge for further
assistance.
1. Select F10 from the Alternate Menu to bring up the Backleak Audit dialog box.
2. Select [Load Testplan] and load any testplan for the injector type fitted.
3. Start the main motor and then press [Start] to start Step 1 of the audit. This applies the
pressure, pulse width, and speed demands shown in the dialog box.
