INSTRUCTION MANUAL
SAFETY GUIDELINES
Your Digital Multitester is designed for both home and automotive use. The follow-
ing Safety Guidelines are provided when it is used for engine or vehicte testing. To
prevent accidents that could result in serious injury and/or damage to your vehicle
or test equipment, carefully follow these safety rules and test procedures.
SAFETY EQUIPMENT
Fire Extinguisher
Never work on your car without having a
suitable fire extinguisher handy. A 5-lb or
larger CO, or dry chemical unit specified for
gasoline/chemicai/electrical fires is recom-
mended.
Fireproof Container
Ragsand flammabie liquids shouldbe stored
only in fireproof, closed metal containers. A
gasoline-soaked rag should be allowed to
dry thoroughly outdoors before being dis-
carded,
Safety Goggles
We recommend wearing safety goggles
when working on your car, to protect your
eyes from battery acid, gasoline, and dust
and dirt flying off moving engine parts.
NOTE: Never look directly into the carburetor
throat while the engineis cranking or running,
as sudden backfire can cause burns.
LOOSE CLOTHING AND LONG HAIR
(MOVING PARTS)
Be very careful not to get your hands, hair or
clothes near any moving parts such as fan
blades, belts and pulleys or throttle andtrans-
mission linkages. Never wear neckties or
loose clothing when working on your car.
JEWELRY
Never wear wrist watches, rings or other
jewelry when working on your car. You'll
avoid the possibility of catching them on
moving parts or causing an electrical short
» circuit which could shock or burn you.
VENTILATION
The carbon monoxide in exhaust gas is
highly toxic. To avoid asphyxiation, always
operate vehicle in a well-ventilated area. If
vehicle is in an enclosed area, exhaust
should be routed directly to the outside via
leakproof exhaust hose.
SETTING THE BRAKE
Make sure that your car is in Park or Neu-
tral, and that the parking brake is firmly
set.
NOTE: Some vehicles have an automatic
release on the parking brake when the gear
shift lever is removed from the PARK posi-
tion. This feature must be disabled when it
is necessary (for testing) to have the park-
ing brake engaged when in the DRIVE posi-
tion. Refer to your vehicle service manual
for more information.
HOT SURFACES
Avoid contact with hot surfaces such as
exhaust manifolds and pipes, mufflers (cata-
lytic converters), radiator and hoses. Never
remove the radiator cap while the engine is
hot, as escaping coolant under pressure
may seriously burn you.
SMOKING AND OPEN FLAMES
Never smoke while working on your car.
Gasoline vaporis highly flammable, and the
gas formed in a charging battery is explo-
sive.
BATTERY
Donotlay tools or equipment on the battery.
Accidentally grounding the “HOT” battery
terminal can shock or burn you and damage
wiring, the battery or your tools and testers.
Be careful of contact with battery acid. Itean
burn holes in your clothing and burn your
skin or eyes.
When operating any test instrument from an
auxiliary battery, connect a jumper wire be-
tween the negative terminal of the auxiliary
battery and ground-on the vehicle under test.
When working in a garage or other enclosed
area, auxiliary battery should be located at
least 18 inchês above the floor to minimize
the possibility of igniting gasoline vapors
HIGH VOLTAGE
High voltage — 30,000 to 50,000 volts ~ is
present in the ignition coil, distributor cap,
ignition wires and spark plugs. When han-
dling ignition wires while the engine is run-
ning, use insulated pliers to avoid a shock.
While not lethal, a shock may cause you to
jerk involuntarily and hurt yourself.
JACK
The jack supplied with the vehicle should be
used only for changing wheels. Never craw!
ind car or run engine while vehicle is on
a jack.

Diode Check
Use this test to check for open or shorted diodes. A good diode will show a
low reading with the test leads connected in one polarity, and a high reading
with the test leads connected in the other polarity. The low reading will be
typically some three-digit number on the display (for example: .673). The
actual number is not critical. The high reading should be infinity (1.).
A shorted diode will have a low reading in both directions. An open diode will
read "1." or "—1." in both directions.
PRECAUTIONS AND PREPARATION FOR MEASUREMENT:
1.Be sure that a fresh nine (9) volt battery is correctly installed in the
multimeter.
2.Compare the position of the selector switch with the anticipated test
result. In the case of voltage or current measurement, always select a
range which is high enough to handle the worst case result! Voltage or
current may be higher than you expect.
3.The BLACK test lead is always inserted in the COM (Common) jack on
the multimeter. The RED test lead must be inserted in either the
))/-E_ V/Q. (Continuity/Diode Volts/Ofims) jack; MA (millidinps jack),
or the 10A (10 Amps) jack depending on the test being performed.
Incorrect placement of the RED test lead may damage the multim-
eter, the circuit under test, or both!
4.Qperate the multimeter only in temperatures between 5°C and 50°C.
(40°F - 122°F), and at 70% or less relative humidity.
5.Turn the SELECTOR switch to the OFF position when testing is com-
pleted. If the multimeter will not be used for an extended period of time,
remove the internal nine (9) voit battery to avoid damage from leakage.
6.Do not store the multimeter in direct sunlight, or in areas of high
temperature or high humidity.
MEASUREMENT PROCEDURES:
1.VOLTAGE MEASUREMENT
a. Set the SELECTOR switch to the required ACV or DCV position.
b. Plug the BLACK test lead into the COM input jack on the muitimeter.
c. Plug the RED test lead into the +} /—>} V/Q input jack on the
multimeter.
d. Connect the test leads to the circuit under test, observing proper
polarity when measuring DC voltage.
e. Read the result on the digital display. If the display reads overrange (1.),
switch to a higher range within the appropriate AC or DC function.
2.0C CURRENT MEASUREMENT
a. Set the SELECTOR switch to the required DCmA position.
b. Plug the BLACK test lead into the COM input jack on the multimeter.
c. Plug the RED test lead into the mA input jack on the multimeter.
d. Connect the test leads to the circuit under test, observing proper
polarity.
e. Read the results on the digital display. If the display reads overrange
(1,), switch to a higher range within the DC milliamps function.
3.10A CURRENT MEASUREMENT
a.Set the SELECTOR switch to the 10A position.
b. Plug the BLACK test iead into the COM input jack on the multimeter.
c. Plug the RED test lead into the 10A input jack on the multimeter.
d. Connect the test leads to the circuit under test, observing proper
polarity.
e. Read the result on the digital display.
4.RESISTANCE MEASUREMENT
a. Set the SELECTOR switch to the required resistance Q OHMS position.
b. Plug the BLACK test lead into the COM jack.
c. Plug the RED test lead into the X> V/Q input jack.
d.Connect the test leads to the circuit under test.
e. Read the result on the digital display. if the display reads overrange
(1.), switch to a higher range within the resistance function.
5.DIODE CHECK
a. Set the SELECTOR switch to the -pp (Diode) position.
b. Plug the BLACK test lead into the COM input jack.
c. Plug the RED test lead into the -D> VIQ input jack.
d.Connect the test leads to the diode under test. The diode must be
removed from the circuit to achieve proper results,
e. Read the result on the digital display.
f. Reverse the test lead connections at the diode.
g. Read the result on the digital display.
h. A good diode will show a low reading with the test leads connected
one way, and infinity (1.) with the test leads connected the other way.
The low reading will typically be some three-digit number on the
display. The actual number is not critical.
6.CONTINUITY CHECKS
a. Plug the RED test lead into the =)))/—pp V/Q. input jack.
b. Plug the BLACK test lead into the COM input jack.
c. Set the SELECTOR switch to the 2009/")J} position.
d.Connect the test lead to the circuit under test. Buzzer sounds it
the resistance at the circuit is below 100 Ohms.
FUSE and BATTERY REPLACEMENT:
All current ranges of this multimeter are fuse protected. Should you exceed
maximum current flow in any of these ranges, the fuse may open. To maintain
safe operation of the multimeter, replace the 200mA fuse only with a 200mA,
250 Voit, 5mm x 20mm fast-acting glass fuse, and replace the 10A fuse only
with a 10A, 250V, 1-1/4 inch fast-acting ceramic fuse. Replace the fuses as
foliows:
1.Turn the SELECTOR switch OFF.
2.Remove the bottom case haif.
3.Remove the battery.
4.Using a small blade screwdriver or other suitable tool, gently pry the
open fuse out of its holder.
5.Install a new fuse.
6.Re-instail the battery, and bottom case half. 7
