Scanner with Data Saving


The classic workshop testing device is increasingly being edged out by the scanner. It is only still necessary for the fast collection of data series. Apart from that, there is too little standardisation. Sometimes the scanner collects more data, somtimes less, depending on the manufacturer. The technology of the collection of data from the control device is quite spectacular, in the continuous function however, still somewhat limited. E.g., during a test-drive, the device can occasionally fail. Only using an additional laptop sometimes helps to secure the data.


The device shown in the above figure initially receives its electricity supply through its own battery. Thus, allowing the input of the vehicle data. As soon as it has given the position and possible interface type, it can be connected, henceforth, can it draw current from the vehicle battery. Now, one has a choice between various areas. This begins, first of all, with an error analysis. If the four-digit display is not sufficient, on the right there is a scroll wheel.
The actual advantage of the device only becomes clear, when it is connected up to a computer/laptop. These have a software which collects the data records from the scanner, and can display them numerically and/or graphically and, if required, also store them to memory. Indeed, one has to become accustomed to the massive ammount of data from some controll devices. Sometimes, through the scanty description of a certain sensor, one is not always quite sure where the signal is coming from. Just imagine, over 50 pieces of data from 69 sensors. The software does however, help with the sorting out.
Initially, in the graphic display, one can follow exactly, up to four values over a certain period (the same as with Bosch). In this case, e.g., one can compare the RPMs with the injection time and possibly, the Lambda-value. A graphic cursor helps through the display of precise, thus better comparable values. If one has found the location where the error (repeatedly) appears, one can call up and consult the other values. The problem can possibly be systematically localised by a further test-drive.
The possibility of being able to save the data, and of course, being able to call them up at wish, should not be underestimated. Should the workshop, e.g., need further advice, this can be attached (also in the form of an e-mail). The adviser can even authorise further tests without actually being there. Data bases of the typical errors can be compiled and consulted when searching for the solution to a problem. Students can study real cases and learn to cope with the flood of data.               Top of page               Index
