23.1. IMPORTANCE AND SUBJECT OF FAULT FINDING

Repair of a radio is an economical activity (if done professionally). Therefore it is an activity during which somebody who is undertaking it has to keep in mind economical questions in order to be able to earn his living.

Therefore the question - which method of fault finding should be chosen in a special case - will be answered normally under its economical aspect.

During the overall activity of repairing a radio the section FAULT FINDING has an overwhelming importance. If a fault has been located it has lost its “horror”, because its remedy requires only some rather simple skills and some knowledge about components and materials.

If repair is done as a business, fault finding is a main factor of calculation of costs. The time consumed for it is a very big portion of the overall time spend for the repair. A quick location of faults is therefore reducing the costs and gives so the professionalist a big advantage in competition.

To be able to choose the fitting method of fault finding under special circumstances, it is necessary to have a general viey of all possible methods to track down faults. An important role play the measuring instruments.

Instruments, finding devices, signalgenerators and so on, are items which are very expensive and therefore must enter the calculation of costs as well.

Even if a beginner does not have all instruments available on the market he has a big advantage if he has a profound knowledge of all possible methods because he is only then able to apply the best method which will cause the smallest costs.
