HIGH-VOLTAGE

DIODE

Measure the resistance: Across two terminals with

an ohm-meter on highest scale.

CHECKOUT PROCEDURE RESULT

Normal reading:

Momentarily indicates several ohms, and

gradually to 10 meg-ohms.

Abnormal reading:

Indicates continuity or 10 meg-ohms

from the beginning.

Normal reading:

Indicate about middle position in one

direction (forward) and infinite ohms in

the reverse direction, using ohm meter

with a 9V battery.

NOTE

- Some digital meter may show more

than 0 ohms or infinite ohms even in a

forward direction because the low mea-

suring voltage of the meter does not

allow the meter to pass through the high

voltage diode. Use an ohm meter with

a 9V battery.

Abnormal reading:

Indicates continuity or infinite ohms in

both directions.
