7.3.3.9. Check of the vypryamitelny block

Check the positive gate.

Fig. 7.26. Scheme of check of conductivity of contacts of the vypryamitelny block


Connect a negative sampler of an ohmmeter to a positive conclusion of the vypryamitelny block, and consistently connect a positive sampler to each of three other conclusions. Be convinced available conductivity (the closed chain) of all three dimensions (fig. 7.26).
Change polarity of connection of samplers of a tester and repeat the first procedure. Make sure that in all three dimensions the chain is opened (resistance strives for infinity).
Check the negative gate.

If conditions of check are not satisfied, replace the block of rectifiers.
