Measuring A Low Resistance - Yamaha e60hmhd Service Manual

ELECTRICAL COMPONENTS ANALYSIS
NOTE:
• When measuring the peak voltage, set the
selector to the DC voltage mode.
• Make sure the peak voltage adapter lead
are properly installed in the digital tester.
• Make sure the positive pin (the "+" mark
facing up as shown) on the peak voltage
adapter is installed into the positive
terminal of the digital tester.
• The test harness is needed for the following
tests.
Measuring steps:
(1)Connect the peak voltage adapter
probes to the connectors.
(2)Start or crank the engine and observe
the measurement.

MEASURING A LOW RESISTANCE

When measuring a resistance of 10 W or less
with the digital tester, the correct
measurement cannnot be obtained bacause
of the tester's internal resistance.
To be obtain the correct value, subtract the
internal resisitance from the displayed
measurement.
Correct value:
Displayed measurement-
internal resistance
NOTE:
The internal resisitance of the digital tester
can be obtained by connecting both of its
probes.
