Observe the engine speed displayed on the top
right screen. When the displayed speed is
stable, press [ENTER] key to perform power
balance test.
Note:
Keep the engine speed at about 1500rpm, for
the test result obtained at this speed is the
most accurate.
Press [ENTER] key, the screen will be displayed
as shown in Fig.7-13. KES-200 will disable each
cylinder in order according to the firing order,
and perform cylinder power balance test
automatically.
Fig.7-13
If a cylinder is disabled, the corresponding
cylinder number displayed under the abscissa
will become gray. For example, when the
cylinder 2 is disabled, the number “2” under the
abscissa becomes gray, as shown in Fig.7-13.
After test, the result will be automatically
displayed on the screen as shown in Fig.7-14.
Note: As shown in Fig.7-14, the digits under
the bar graph are cylinder numbers; the
value under the cylinder number is the
percent (%) speed drop. If the engine speed
increases when a cylinder is disabled, the
displayed height of the bar is zero, and the
percent speed drop is a negative value for
the cylinder.
