1) Measure the resistance:
With an ohm meter on Rx1 scale.
a. Primary winding;
b. Filament winding;
c. Secondary winding;
2) Measure the resistance:
With an ohm meter on highest scale.
a. Primary winding to ground;
b. Filament winding to ground;
Normal reading:
a. Approximately 1.0 ohms.
b. Less than 1 ohm.
c. Approximately 60 ohms.
Normal reading:
a. Infinite ohms.
b. Infinite ohms.
Note: Remove varnish of measured point.
Measure the resistance: Across two terminals
with an ohm meter on highest scale.
Normal reading:
Momentary indicates several ohms,
and gradually to 10 meg-ohms.
Abnormal reading:
Indicates continuity or 10 meg-ohms
from the beginning.
Measure the resistance: Across two terminals
with an ohm meter on highest scale.
Normal reading:
Indicate about the middle position in
one direct ( forward ) and infinite ohms
in the reverse direction, using meter
with a 9-volts battery.
NOTE
- Some digital meter may show over
even in a forward direction because low
measuring voltage of meter does not
allow the meter to pass through the
high voltage diode.
Abnormal reading:
Indicates continuity or infinite ohms in
both directions.
Measure the resistance: Across two terminals
with an ohm meter on highest scale.
Normal reading:
Indicate infinite ohms in both direc-
tions.
Abnormal reading:
Indicates continuity in both directions
or continuity in one direction and
infinite ohms in reversed direction.
