DIGITAL CIRCUIT TESTER

Digital tester

NOTE:
" " indicates a continuity of electric-
ity which means a closed circuit at the
respective switch position.

MEASURING THE PEAK VOLTAGE

WARNING
When checking the peak voltage do not
touch any of the connections of the digital
tester lead wires.
NOTE:
• When checking the condition of the ign-
ition system it is useful to know the
peak voltage.
• Cranking speed is dependant on many
factors (e.g., fouled or weak spark
plugs, a weak battery). If one of these is
defective, the peak voltage will be
lower than specification.
• If the peak voltage measurement is not
within specification the engine will not
operate properly.

PEAK VOLTAGE ADAPTOR

NOTE:
The peak voltage adaptor should be used
with the digital circuit tester.
