the vehicle by means of:
R
The OBD diagnostic cable (Fig. 3, Pos. 2), or
R
The OBD diagnostic cable and also the UNI connect-
ing cable (Fig. 3, Pos. 3; special accessory), or

Switching on

¶
Switch on the KTS 340 with the button.
"
After the system has started, the KTS 340 remains
in the "Vehicle identification" start screen. The start
screen is always displayed after switch-on.
!
If the KTS 340 is supplied with power via the power
supply unit, always use the power supply unit
provided. Do not use power supply units with less
power than 15V/3A, such as those supplied with the
KTS 200 or KTS 5xx, for example.
The KTS 340 is usually supplied with power via the
OBD diagnostic socket in the vehicle. If you do not
know where in the vehicle the OBD diagnostic socket is
located, we recommend finding it by means of KTS 340
control unit diagnosis.
i
In some vehicles, the cigarette lighter socket only
supplies power when the ignition is turned on.
i
If a test step involves starting the engine, the battery
voltage may drop to such an extent that supply via
the vehicle is no longer guaranteed. In such cases
it may be necessary to supply the KTS 340 via the
power supply unit.
i
In some vehicles, the ignition must be switched on in
order for power to be supplied via the OBD interface.
If the KTS 340 is connected to a PC/laptop via the USB
connecting cable, we recommend supplying it with
power via the power supply unit provided.

Switching off

¶
Press the button for approx. three seconds.
"
The KTS 340 is switched off.
If it is only being run off the battery, the KTS 340 is
switched off if the battery voltage drops below 8 V or if the
device has not been used for ten minutes (factory setting).
If the KTS 340 is being supplied via an external power
source (e.g. OBD diagnostic cable or power supply
unit) and is not used for a lengthy period, the bright-
ness of the LCD touchscreen is reduced.

Notes on multimeter

Danger from high voltage!
There is a risk of potentially fatal voltage if
measurements are taken without a ground
cable.
¶
If no diagnostic cable is connected, use
the ground cable provided to make a
ground connection between the KTS 340
and vehicle ground before taking U, R or I
measurements.
¶
Connect the ground cable as close as pos-
sible to the object to be measured.
¶
Use KTS modules only on the vehicle and
not for measuring voltages > 60 VDC, 30
VAC or 42 VACpeak! Do not perform any
measurements on ignition systems.
¶
Do not perform any measurements on igni-
tion systems.
¶
Only use the test cables provided (with
contact protection).
¶
Always plug in the test cables at the
KTS 340 first and then on the vehicle.
¶
Do not lay unshielded test cables close to
sources of major interference such as igni-
tion cables.

Touchscreen with stylus

The touchscreen of the KTS 340 is operated with the sty-
lus. Touch the application you require with the stylus.
i
You can perform "Touchscreen calibration" in the
Service menu via "User settings >> Customer

ly above the calibration points. Click on the calibra-
tion points as accurately as possible.
