INSPECTION
CAUTION:
All measuring instruments should be han-
G
dled with special care. Damaged or mis-
handled instruments will not measure
properly.
On an instrument powered by dry batter-
G
ies, check the battery's voltage periodi-
cally
and
necessary.
Digital multimeter
NOTE:
Throughout this chapter the digital multim-
eter's part number has been omitted. Refer
to the following part number.
Digital multimeter:
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
G
less with the digital tester, the correct
measurement
because of the tester's internal resistance.
G
To obtain the correct value, subtract the
internal resistance from the displayed
measurement.
G
The internal resistance of the tester can be
obtained by connecting both of its termi-
nals.
