This meter is a handheld and battery operated professional automotive multimeter
des igned to provide
troubles hooting solutions
t
o the most dif
f
icul t problems
encountered with today’s sophisticated automotive electronic systems.
The User’s Manual tells you how to use this meter. You may also need a manual
that provides technical information for the vehicle you
plan to
test. The
most
important information resources are the vehicle’s repair service manuals generally
available for purchase through automotive dealers. They are also available through
a number of publishers that specialize in providing technical information manuals to
the independent repair garages.
This User’s Manual should be used as a guide to get you started in troubleshooting.
Your real learning can best be accomplished through experience. As you become
more proficient in using the automotive multimeters to
t
roubleshoo
t
, you will very
quickly learn how certain
electrical symptoms can relate
to various driveability
problems.
This meter is much more than a standard multimeter. This meter can replace the
following several automotive testers.

er
gets a
quick
and accura
t
e diagnosis of the complete O

circuit. This me
t
er is capable of
sending
a Rich/Lean
signal to the ECM, and
displaying crossing-per-second (CC) and O
2
voltage simultaneously,
when the
secondary display shows test results.
This meter has a bright LED backlight as well as enhanced LCD with larger digits,
wide viewing angle and on screen menu selection
.

Overmoulding technology in the case disperses various shock over more of the
case than a conventional rubber boot design. Convenient closed case calibration
allows adjustments to be made directly through the RS-232C port.
