Safety Precautions
Read and follow thesesafety precautions.
Never apply voltages to the meter that exceed the limits givenin the
specifications. Never apply more than 1000V DC or 750V RMS AC between
the input jacks and ground.
+Use extreme caution when working with voltages above 100V. Always
disconnect power from the circuit you are measuring before you connect test
leads to high-voltage points.
+Never connect the test leads to avoltage source when you set the meter's
function dial to H2/LOGIC, »)/D+, QAF mA/A/== or yA/A/=2.
+Always discharge any capacitors of the circuit under test before you attach
test leads.
+Always turn off power and disconnect the test leads from the circuit you are
testing before you replace the meter's battery or fuse. Never operate the meter
unless its back cover and battery cover are in place and secured.
+Never try to probe with both test leads at the same time or hold both test
leads in one hand.
+The testleads supplied with your meter are rated for 1000V. Use only test
leads ofthe same rating with the meter. You can order replacement leads
from your local RadioShack store.
+Donotuseafuse of brand or rating other than those specified here. Doing so
might damage your meter.
+Because many AC/DC sets have apotentially hot chassis, be sure the top
of your workbench and the floor underneath it are made of non-conductive
materials.
+Your multimeter is designed primarily to measure household AC voltages.
Because of the dangers inherent in measuring three-phase circuits, we
strongly recommend you do not use this meter to measure 3-phase, line-to-
line voltage. If you still want to, put on protective clothing—a face shield and
fireproof gloves and upper body protection is required before measuring. If
you do not have this protection, DO NOT MEASURE THESE CIRCUITS.
«Toreduce the risk of fire or shock hazard, do not expose this product to rain
or moisture. For indoor use only.
+When you are not using the meter, always turn it off.
+Ifthis equipment is used in amanner not specified in this user's guide, the
protection provided by the equipment may be impaired.
This meter is fully calibrated and tested. Under normal use, no further adjustment
should be necessary. If the meter requires repair, do nottry to adjust it yourself.
Take it to your local RadioShack store.

installed.
Care and Maintenance
Keep the meter dry; if it gets wet, wipe it dry immediately and make sure that the
meter is completely dry before using it. Use and store the meter only in normal
temperature environments. Handle the meter carefully; do not drop it.
To keep the meter looking new, occasionally wipe it with acloth slightly dampened
with water. Do not use harsh chemicals, cleaning solvents, or strong detergents
to clean the meter.

Setup
@Install Batteries
1. Remove the rubber boot ifit is attached
2. Turn off your meter. Loosen the screw and remove
the battery cover.
3. Insert two AA batteries (not supplied), matching
the polarity symbols (+ and =) marked inside.
4. Secure the battery cover with the screw.
Battery Notes:
+Useonly fresh batteries of the required size and
recommended type.
+Dispose of old batteries promptly and properly. Do not burn or bury them.
+Ifyou do not plan to use the meter for amonth or more, remove the batteries.
Batteries can leak chemicals that can destroy electronic parts.
«= When[Z3 appears or the meter stops operating properly. replace the batteries.
(@ Use the Stand (Optional)
You can fold out the stand on the back of the meter to
place it upright on aflat surface for easier viewing.
®Use the Rubber Boot
(Optional)
The rubber boot protects your meter from damage and stores the test leads. You
can also use it to mount your meter on awall with ascrew
(not supplied).
Flip up to mount on ascrew.
Store the test leads
when notin use.

@Connect the Test
Leads
1. Remove the plastic plugs before
using your test leads.
2. Slide up the Sliding Guard to
show the test lead sockets.
3. Plug the black test lead into
~COM (common), then plug
the red test lead into +V.mA.Q.
To measure current higher than
400maA, plug the red test lead into
+10A MAX instead of +V.mA.Q.
AN WARNING:
=Although the test leads are rated for
1000 volts, and the maximum rating of
this meteris 1000 volts DC /750 volts
RMS AC, do not try to measure voltage
greater than 1000 volts DC /750 volts
RMS AC.
+The meter sounds awarning tone when you
set it to measure anything except current and
you connect atest lead to +10A MAX. This
reminds you not to touch the circuit with the
test leads.

2. Pressand hold the HOLD and SELECT buttons simultaneously, then turn on
the meter. PLoc appears until you release both buttons.
To reactivate the auto power off function, turn the meter off, then back on.
Select aFunction and Range
Each position on the function dial accesses one or more individual functions.
To select afunction:
1. Turn the function dial to the position with the desired function
2. Press SELECT to toggle between the functions in each position. The unit of
measure that appears on the display shows the currently set range.
3. Press RANGE repeatedly to select arange.
Note the position of the decimal:
IF8.000V appears. the meter is set to measure less than 4volts. IF3380V
