How to Start
z
After connection, insert the engine analysis
cartridge into the cartridge slot of the main unit,
and then start KES-200 to enter the start
interface.
z
On the start interface, click any button except
[Reset], [Power] and [Exit] to enter the main
menu.

Click [4] to select [4. Starting system analysis],
the screen will display the function menu of
starting system analysis as shown in Fig.5-01.

Starting Voltage
Click [1] on the function menu of starting system
analysis, the screen will display the starting voltage
test mode as shown in Figure a-2. The aim of starting
voltage test is to test the capability of the battery to
maintain specified voltage supply. Some alkaline
battery can maintain static voltage after charging; but
when perform starting test, it supplies required starting
current to the KES-200, and thus resulting in the drop
of battery voltage. When the battery voltage drops the
allowable voltage, the engine may not start.
To test the starting voltage, just connect the battery clip
to the battery (“+” to “+” and “-“ to “-“), connect the main
cable, and then start the engine.
At the beginning of start, the voltage wave should drop
2V or more, during the process of continuous start, the
voltage should maintain the status after drop. The
voltage drop for poor battery will be larger than that of
the normal battery.
After connection and starting the engine, the screen
will display the actual staring waveform as shown in
Fig.5-02.
Fig.5-02
On the starting voltage waveform:
z
Initial value: the battery voltage before starting of
engine.
z
End value: the battery voltage after starting of
engine.
Starting Current
The aim of starting current test is to test the discharge
current of battery during the starting of engine. The
starting current may be used to analyze the load
condition of engine during start. Hot start requires
larger current than cold start.
Connect the test cable as shown in Fig.5-03, and then
start the engine. Click [2] on the function menu of
starting system analysis, the screen will display the
actual starting current test mode as shown in Fig.5-04.
