CHECKOUT PROCEDURE
Ohm-Meter
- 5 -
Normal reading :
Momentarily indicates several Ohms,
and gradually returns to 10 Meg-Ohms.
Abnormal reading :
Indicates continuity or 10 Meg-Ohms
from the beginning.
Figure 7
Normal reading :
Indicates about the middle position in
one direction (forward direction) and
infinite Ohms in the reverse direction,
using meter which is provided with a
9 volt battery.
--Some digital meter may show over
even in a forward direction because
low measuring voltage of meter does
not allow the meter current to pass
Figure 8
through the High Voltage Diode.
Abnormal reading :
Indicates continuity or infinite Ohms
in both directions.
