COMPONENT CHECKOUT PROCEDURE RESULTS
1) Measure the resistance :
Normal readings :
With an ohmeter on Rx1 scale.
a. Primary Winding ;
Approximately 1.75 ohms.
b. Filament Winding ;
Less than 1 ohm.
c. Secondary Winding ;
Approximately 90.11 ohms.
2) Measure the resistance :
Normal readings :
With an ohm-meter on highest scale.
a. Primary winding to ground ;
Infinite ohms
b. Filament winding to ground ;
Infinite ohms
Note : Remove varnish of
measured point.
1) Measure the resistance : Across two terminals with an Normal reading :
ohm-meter on highest scale
Momentarily indicates several
ohms, and gradually returns
to 10 Meg-ohm.
Abnormal reading :
Indicates continuity or 10M
Ω
from the beginning.
Measure the resistance : Across two terminals with an
Normal reading :
ohm-meter on its highest scale.
Indicates over 10M
Ω
in one
direction (forward direction)
and infinite ohms in the
reverse direction, using meter
which is provided with a 9-volt
battery.
NOTE
Some digital meters may
show over even in a forward
direction because low
measuring voltage of meter
does not allow the meter
current to pass through
the high voltage diode.
Abnormal reading:
Indicates continuity or infinite
ohms in both directions.
