2.9.3 Current pick-up 100A (VAS 6356/4A) and 1800 A (VAS 5051B/

or VAS 6356/11)

The 100 A and 1800 A current pick-ups (optional) consist of an 8-pin connector (with yellow marking), the cable and the actual current pick-up.

Fig. 2-9 100 A current pick-up

The current pick-up can be opened and can then be laid around the cable whose current is to be measured. Cables can be adapted up to a diameter of 26 mm (100 A current pick-up) or 32 mm (1800 A current pick-up). The level of measurement accuracy depends to a large degree on being able to close the two halves of the pick-up completely without there being any gap. To avoid measurement errors due, for example, to dirt within the root area, both pick-ups have a locking control mechanism. The software thereby receives a signal that the two halves of the pick-up are closed and that a measurement can now be made. Furthermore, the 100 A pick-up is also equipped with a control LED in the grip (see fig. 2-9). If the pick-up is not correctly connected then the LED lights up. At the same time, the following message appears in the information window to the right on the tester: Current pick-up not closed!

The measurement result depends on direction.

Warning! When using the current pick-up

Danger caused by improper use

Without rated measuring category. Measurements at current circuits that are connected directly to the mains are not permitted! For this reason, use the current pick-up only for measurements on the vehicle. Take measurements only at insulated leads! The current pick-up is only permitted for rated voltages up to 300 V!

2.9.4 Trigger clamp VAS 6356/6

The trigger clamp consists of a 5-pin connector (with black marking), the cable and the actual trigger clamp.

Fig. 2-10 Trigger clamp

The trigger clamp can be opened and can then be laid around the ignition cable to be used in triggering. Ignition cables up to 11 mm in diameter can be adapted. The trigger clamp measures the starting pulse of which the course of the signal is to be displayed on the oscilloscope. Clamp the trigger clamp to ignition cable 1, for example, if you want to display a signal from the time of ignition of the first cylinder.

Warning! When using the trigger pick-up

Danger caused by improper use

Without rated measuring category. Measurements at current circuits that are connected directly to the mains are not permitted! For this reason, use the trigger pick-up only for measurements on the vehicle. Take measurements only at insulated leads!

2.9.6 Temperature sensor VAS 5051/70

The temperature sensor consists of a 10-pole pin plug (marked in green), the cable and the sensor, which is made up of a hand grip and a 1 m long flexible protective tube made of Teflon with an adjustable conical rubber seal. A PT100 element is located on the tip of the dipstick. The rubber seal performs two important functions:

 Determining the dipstick immersion depth  Hermetically sealing the measurement point

Fig. 2-12 Temperature sensor (example)

Determining the immersion depth of the dipstick

The immersion depth of the dipstick must be set with the rubber sealing according to the length of the oil dipstick. This thereby limits the immersion depth of the dipstick, e.g. in the oil sump. The immersion depth can differ depending on the vehicle.

Caution!

If the immersion depth is not set correctly using the rubber sealing, then the temperature sensor may be destroyed and the engine may be damaged!

Air-tight closing of the measurement point

The conical design of the rubber sealing allows the measurement point to be closed in an air-tight manner.

3 Operation

This chapter describes the operation of the VAS 6356, provided that it does not concern operating the program via the tester or the specified notebook.

3.1 Switch on VAS 6356

The VAS 6356 does not have an on/off switch. As soon as it is supplied with current via the table power adapter, the VAS 6356 begins its " start-up" procedure. VAS 6356 can be supplied with current even by the vehicle electrical system*. Adapters with connections for the cigarette lighter or the battery can be delivered on request*.

Note

Do not attempt to operate the VAS 6356 during start-up.

3.2 Switching off VAS 6356

Disconnect the power supply of the VAS 6356.

* Not available in USA!

Operation

3.3 VAS 6556 workshop trolley

Fig. 3-1 Workshop trolley

The workshop trolley is used for mobile use of the VAS 6356 in the workshop. It is mounted on four rollers to allow it to be easily pushed within the working environment. All workshop trolleys are equipped with a dust-protective cover. It can be folded together during operation and stored in the storage compartment of the workshop trolley.

Mobility

Both front wheels of the workshop trolley have been equipped with brakes to allow it to be fixed at its location. Release the brakes to move the trolley. You can push or pull the trolley to its new location using the grips on the left or right side. You can then lock the brakes at the new location.

Operation

3-3

3.4 Measurement cables

Diagnostic and measurement cable connections are coded by colour and mechanically. The cable bushing matches the colour of the sockets. The mechanical coding requires that the red point of the connector is aligned with the red point at the plug when establishing a connection. The plugs can easily be inserted into the sockets without using much pressure when so aligned.

Fig. 3-2 Correct handling of a plug at the VAS 5356

To disconnect a plug from the VAS 6356, pull the locking collar of the plug upwards, thereby also pulling the plug from the socket.

Note

The plugs are not threaded and turning them with force may damage them (see Fig. 3-2).

Only grip the plug bushing.

The red dot leader points forwards.

5.2.2 Measurement cables

5.2.2.1 URDI measurement cable

A function test of the URDI measurement cable is carried out as follows. If the test results do not match the required values then there is a fault in the corresponding URDI measurement cable. In this case, please submit a fault report in accordance to Section 5.3.

The URDI measurement cable is best checked using a comparative measurement. Check the "voltage measurement" function, e.g. by connecting the leads to a vehicle

battery. In the "resistance measurement" function, simulate an "open circuit"

(Display: +++++ MΩ) and "short-circuit" (near the display of 0.000 kΩ). You can also measure known resistances, e. g. of a relay coil (normally approx. 90 Ω).

When checking the diodes, you can also simulate an "open circuit" and "short-circuit". However, a diode is required for additional tests.

To check the " inline current measurement" function you must use a circuit of max. 2 A.

Troubleshooting

5-18

5.2.2.2 DSO measurement cables

Carry out a function test of the DSO measurement cables as follows. If the test results do not match the required values then there is a fault in the corresponding DSO measurement cable. In this case, please submit a fault report in accordance to Section 5.3.

1. Connect a DSO measurement cable to the DSO1 socket.

2. Press the Voltage DSO1 button in Test Instruments operating mode, Multimeter mask. Select DC voltage as the type of measurement and the automatic range selection.

3. Connect the measuring tips of the DSO measuring cable with a charged car battery. The measurement value that is displayed must be the same as the battery voltage (between 11 and 14 V).

4. Check the freeze image selection by pressing the button on the red/black probe tip. The measurement value is frozen, the "freeze frame" button must appear to be pressed on the screen.

Carry out a comparative measurement between URDI and DSO:

1. Release the freeze frame by pressing the button again in order to continue the measurement.

2. Additionally connect the URDI measurement cable to the VAS 6356 and the vehicle battery. Its correct functioning should have been checked before connecting it.

3. Press the Voltage U/R/D button. Select DC voltage as the type of measurement and the automatic range selection.

4. In both displayed measurement functions (DSO1 and U/R/D), the difference in the measured values must be 0.2 V.

Repeat the function test with the second DSO measurement cable.

Note

Both DSO measurement cables are identical and can be exchanged for testing.

Troubleshooting

5-19

5.2.2.3 Current pick-ups

Carry out a function test of the current pick-ups as follows. If the test results do not match he required values then there is a fault in the current pick-up. In this case, please submit a fault report in accordance to Section 5.3.

1. Connect a current pick-up to the VAS 6356.

2. Press the Current pick-up button in Test Instruments, mask Multimeter. The current pick-up must be automatically recognized. Select DC current as the type of measurement and the automatic range selection.

3. Open and close the current pick-up several times without connecting it to a live cable. The value measured must change considerably between these two states (open and closed). In case of the 100 A pick-up, check whether the LED at the current pick-up correctly displays the conditions "opened (LED is on) / closed (LED is off)".

Now check the calibration of the current pick-up:

1. Press the Calibrate button on the screen. Close the message displayed by pressing the OK button. At most, the measured value displayed after calibration must equal the tolerance in the lowest measurement range (see section 7.3.1).

2. Connect the current pick-up to a battery cable or another cable of a consumer in a vehicle. All consumers and the ignition of the vehicle should be switched off at first. The displayed measurement result should only change marginally (environmental influences).

How to perform a comparative measurement:

1. Switch on a consumer, e.g. the parking light. The power consumption should be known as accurately as possible. Take this value as a starting point. The measured value should be the same as this value.

2. Pull the current pick-up from the cable carrying the current and plug it back in, reversed by 180°. The difference must remain within the stipulated tolerance (see Section 7.3.1).

Troubleshooting

5-20

5.2.2.4 Trigger clamp and kV pick-up

The trigger clamp and kV pick-up can only be tested together. Carry out a function test as follows. If the test results do not match the required values then there is a fault in one of the sensors. In this case, please submit a fault report in accordance with Section 5.3.

1. Connect the trigger clamp and the kV pick-up to the VAS 6356.

2. Select the DSO mask in operating mode Test Instruments.

3. Connect both pick-ups via the same ignition cable (secondary side of the ignition coil) to a vehicle with a 4 or 6 cylinder engine.

4. Press the Preset measurement button in the DSO mask, select the Secondary ignition voltage curve in the selection list that appears, and confirm with the Display button. The DSO mask will appear with the set curve in the background. At the same time, all DSO settings will be made automatically.

5. Start the vehicle's engine. The typical ignition signal must be displayed dynamically, i.e. the picture is re-written once or twice per second if the kV pickup and trigger clamp are working correctly.

If the trigger clamp is faulty then the following message appears in the window at the top right:

No trigger

If the kV pick-up is faulty then a horizontal line may only be displayed or else a signal curve with much too small an amplitude.

Note

Depending on the type of vehicle used, the amplitude of the ignition signal may fluctuate between 4 and 40 kV. The combustion voltage is normally between 600 and 1200 V, and the combustion duration should be between 1 and 6 ms. The shape of the curve may vary depending on the manufacturer of the ignition coil.
