APPLICATIONS
measured to provide an indication of rectifier
condition. The forward resistance should be low
and the reverse resistance very high.
CAPACITOR CHECKS
Simple capacitor checks, designed to indi-
cate good, open and short conditions for many
types of capacitor, can also be performed witn
the ohmmeter circuit. These are a guide only,
and the results should always be confirmed.
Use the R x 10,000 range for best results.
A good capacitor will allow current to
flow, deflecting the meter pointer, while it is
charging up to the applied voltage supplied by
the multimeter batteries. After swinging to the
right, the pointer will gradually return to
infinity at the left side of the scale. The
greater the capacity, the greater the deflection
and the longer it will take for the pointer to
return to infinity.
Àn open capacitor has infinite resistance;
no current will flow, and there will be no move-
ment of the pointer. Very small capacitors will
produce only & very small deflection with a very
rapid return to infinity. The meter must be very
closely observed if you are to distinguish between
these conditions.
А shorted capacitor will produce a pointer
deflection which will persist. The meter will
continue to indicate г finite resistance value.
