CAUTION:
All measuring instruments should be han-
dled with special care, or the correct mea-
surement is impossible.
On an instrument powered by dry batter-
ies, the latter should be checked for voltage
periodically and replaced, if necessary.
NOTE:
“
” indicates the terminals between
which there is a continuity of electricity; i.e.,
a closed circuit at the respective switch
position.
Peak voltage measurement
NOTE:
●
The coil output varies greatly at cranking
speed.
●
Cranking a cold engine with the plugs in
and a weak battery does not enable
proper readings.
Low resistance measurement
When measuring a resistance of 10
Ω
or
less using the digital tester, the correct
measurement cannot be obtained because
of the tester’s internal resistance.
To obtain the correct value, subtract this
internal resistance from the displayed mea-
surement.
NOTE:
The internal resistance of the tester can be
obtained by connecting both of its termi-
nals.
Digital multimeter:
J-39299
Peak volt adapter:
YU-39991
