6.5 Leakage Test
Leakage test is to inspect the sealing condi-
tions of the injector needle valve under system
pressure and to find out if the injector is drib
-
bling.
Procedures (Installation refer to Uniformity/
Sprayability Test):
1) Before doing leakage test, please press
DRAIN
icon to drain the rudimental residual
test liquid from the measuring cup.
2I) Select
Leakage Test
function and press
EN-
TER
key to run.
At this time the system pressure can be adjus-
ted by pressing < or > key to observe dribbling
from the injector the pressure is adjusted pre-
ferably 10% higher than manufacturer’s speci-
fications.
3) When the test is over, the equipment will au-
tomatically stop and the buzzer will ring simul-
taneously.
Note:
In general the drip of the injector should be
less than 1 drop within 1 minute (or in accor-
dance with the specifications). The default
time of the system is 1 minute.
6.6 Injecting Volume Test
Injecting volume test is to check if the injecting
flow in 15 seconds meets the specifications
for injecting amount. The deviation reflects
the wear or clogging in the injector, instead of
electrical parameter variation.
Procedures (Installation refer to Uniformity /
Sprayability Test):
1) Before this test, press
DRAIN
icon to drain
the test liquid from the measuring cup if there
is any.
2) Choose
Injecting Volume
Test function and
press
ENTER
key to start the test.
Adjust the fuel pressure by pressing < or > key
according to the injector specification.
3) When the test is over, the equipment will
stop automatically at the ring of the buzzer.
