Intake Manifold Vacuum (Optional)
Introduction
As the air suction of the engine is an
intermittent process, it may produce intake air
pressure pulse. We can image that the
waveform of the intake air vacuum includes
the information related to the intake and
exhaust mechanism, such as air mixture
mechanism, air valves and cylinder rings, etc.
Therefore, we can analysis some troubles of
the related components by performing
waveform test of the intake air vacuum without
disassembling the engine.
Connection
Connect the black BNC terminal of the intake manifold
vacuum adapter to the channel 1 (CH1) of KES-200;
connect the red BNC terminal to the channel 2 (CH2).
See Fig.3-13 for detailed connection.

Start to Test
Insert the engine analysis cartridge into the main unit.
Then switch on the main unit. The unit will enter the
start interface. On the start interface, press any key
(except [Reset], [Power] and [Exit]), the screen will
display the main menu.
Press [2] key on the main menu to enter the
[MULTIMETER] function. The screen will display the
menu for multimeter as shown in Fig.3-14.
