INSPECTION
CAUTION:
All measuring instruments should be han-
dled with special care. Damaged or mis-
handled instruments will not measure
properly.
On an instrument powered by dry batter-
ies, check the battery's voltage periodi-
cally
and
necessary.
Digital tester
NOTE:
Throughout this chapter the digital tester's
part number has been omitted. Refer to the
following part number.
Digital tester:
J-39299/90890-06752
NOTE:
"
" indicates a continuity of electric-
ity; i.e., a closed circuit at the respective
switch position.
Low resistance measurement
NOTE:
When measuring a resistance of 10 Ω or
less with the digital tester, the correct
measurement
because of the tester's internal resistance.
To obtain the correct value, subtract the
internal resistance from the displayed
measurement.
The internal resistance of the tester can be
obtained by connecting both of its termi-
nals.
