After the "leak test", fit the injection chamber on the
component and connect the hose 1 680 712 362
to the quick-release coupling of the injection cham-
ber (fig. 41, item 6) and via the inlet filter to the
"Test connection for injected fuel quantity" (Fig. 41,
item 4).

CRI Piezo testing is described in the Online Help.
7.5 Topping up test oil
The test oil must be topped up if the level drops below
the mark on the oil level indicator (Fig. 1, item 8).
!
If it is poured in too quickly, the test oil may run out
at the turned-up flushing drain or at the connection
for external extraction.
1. Turn the flushing drain (Fig. 3, item 6) upwards.
2. Pour test oil (ISO 4113) very slowly and carefully
into the jet chamber (Fig. 3, item 4).
i
If the level is exactly on the mark of the oil level indi-
cator, a maximum of 1.5 l of test oil can be added.
3. Pour in test oil as far as the upper visible area of the
oil level indicator.
 The EPS 205 is ready for operation again.

7.7 Updating software
!
We recommend database back-up before updating
the system software (see Online Help).
!
All customer data, protocols, user-generated test
procedures and reference pressure values for com-
mon rail injectors stored on the EPS 205 are lost on
restoring the operating system with the Product Re-
covery CD. We recommend making a back-up copy
of the database before restoring the operating sys-
tem. Following installation of the Product Recovery
CD, pressure sensor calibration must be performed
again by Customer service/Testing department
personnel. The calibration values for the nozzle-and-
holder assembly (DHK/UI) and the calibration factor
for the flowmeter are stored on the trigger electron-
ics and are not lost on restoration.
Software updating is described in the Online Help un-
der "System >> Software".
7.8 Faults
i
Follow the instructions on the screen with regard
to faults in the EPS 200 system software. Customer
service must be notified if the problem cannot be
rectified.
Fault
LCD remains blank following
switch-on.
Test oil mist is not extracted
properly during spray pattern
test.
After clicking onto the touch
screen with the pen, the
mouse pointer does not
appear at the same location.
en
Remedial action
Check electrical connection
(if power is being supplied
properly, the fan on the back
of the EPS 205 must run and
the ring lamp in the injection
chamber must light).
1. Check compressed air
connection
(0.5 MPa − 0.8 MPa).
2. Make the correct setting
for the internal extraction
controller.
Perform touch screen
adjustment (see Online Help).
