be switched during a test, ALWAYS remove the test leads
from the circuit being measured before switching settings.
•
To avoid possible electric shock, instrument damage, and/or
equipment damage when taking voltage or current measure-
ments, DO NOT exceed the maximum value of the selected
range.
•
If the tester is used near high noise Radio F requency (RF)
generating equipment (spar k plug wires , ignition coils or
alternator), the display may become unstable or indicate large
errors. If you obtain err atic readings dur ing use, isolate the
tester as far away as possible from these components.

TESTING PROCEDURES

A. AC/DC VOLTAGE MEASUREMENT
To avoid possible electric shock, instrument damage
and/or equipment damage, DO NOT attempt to measure
voltages ABOVE 600V AC/DC or take measurements if
the voltage is unknown. 600V AC/DC between the COM
and V jacks is the maximum voltage that this instrument
is designed to measure. The "COM" terminal potential
should not exceed 300V AC/DC measured to ground.
1. Plug the BLACK test lead into "COM" jack of the tester; plug
the RED test lead into the " V" jack.
NOTE: If alligator clip adapters (not included with tester) are to
be used on the test leads , use suitable rated and UL cer tified
alligator clips.
2. Set the tester' s Function/Range Selector Switch to the
appropriate
Controls and Indicators, Items 1 and 2).
3. Place the RED test lead onto the positiv e (+) side of the item
being tested and the BLA CK test lead onto the negativ e (-)
(across the source/load) side of the item.BE CAREFUL not to
touch any energized conductors with any part of your body.
4. Read the results on the display.
