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 replace the batteries if
necessary.
Digital tester
NOTE:
Throughout this chapter the digital tester’s
part number has been omitted. Refer to the
following part number.
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 cannot be obtained
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.
