INTRODUCTION
•
Congratulations. You have purchased a precision instr ument
manufactured to the highest quality standards . This Digital
Automotive Tester is a general-purpose instrument designed
for use in gener al electronics, home electr ical applications,
and automotive electrical/electronic systems.
•
This tester is designed to
test
or
measure
AC voltage, DC
voltage, DC current, AC current, resistance, diodes, continu-
ity, frequency, duty cycle, pulse width, rpm and temperature.
•
Please take the time to read these operating instructions thor-
oughly and completely. Failure to follow these instructions may
result in electrical shock, instrument damage and/or damage
to the equipment under test. Always use e xtreme caution
when working on or around electrically operated equipment.

To prevent electrical shock and/or damage to the tester or the
equipment under test, observe the following safety precautions:
•
DO NOT apply more than the r ated voltage, as marked on
the tester, between terminals or between any terminal and
earth ground.
•
Use caution when working above 30V AC rms, 42 V peak, or
60 V DC. Such voltages pose a shock hazard.
•
To avoid false readings that could lead to possib le electric
shock or personal injury, replace the batteries as soon as the
low battery indicator
displays.
