WARNING: USE EXTREME CAUTION IN THE USE OF THIS DEVICE.
Improper use of this device can result in injury or death. Follow all safeguards
suggested in this manual in addition to the normal safety precautions used in
working with electrical circuits. DO NOT service this device if you are not
qualified to do so.
SAFETY INSTRUCTIONS
This meter has been designed for safe use, but must be operated with caution.
The rules listed below must be carefully followed for safe operation.
1. NEVER apply voltage or current to the meter that exceeds the specified
maximum:
Input Protection Limits
Function Maximum Input
V DC or V AC 500V AC and DC
mA DC 500mA DC
Resistance 50V DC/AC
2. USE EXTREME CAUTION when working with high voltages.
3. DO NOT measure voltage if the voltage on the "COM" input jack exceeds
600V above earth ground.
4. NEVER connect the meter leads across a voltage source while the
function switch is in the current or resistance mode. Doing so can
damage the meter.
5. ALWAYS discharge filter capacitors in power supplies and disconnect the
power when making resistance tests.
6. ALWAYS turn off power and disconnect test leads before opening the
covers to replace the fuse or battery.
7. NEVER operate the meter unless the back cover and the battery and fuse
covers are in place and fastened securely.
8. If the equipment is used in a manner not specified by the manufacturer,
the protection provided by the equipment may be impaired.
SAFETY SYMBOLS
This symbol adjacent to another symbol, terminal or operating
device indicates that the operator must refer to an explanation
in the Operating Instructions to avoid personal injury or damage
to the meter.
This WARNING symbol indicates a potentially hazardous
situation, which if not avoided, could result in death or serious
injury.
This CAUTION symbol indicates a potentially hazardous
situation, which if not avoided, may result damage to the
product.
This symbol advises the user that the terminal(s) so marked
must not be connected to a circuit point at which the voltage
with respect to earth ground exceeds 500V.
This symbol adjacent to one or more terminals identifies them
as being associated with ranges that may, in normal use, be
subjected to particularly hazardous voltages. For maximum
safety, the meter and its test leads should not be handled when
these terminals are energized.
This symbol indicates that a device is protected throughout by
double insulation or reinforced insulation.

BATTERY INSTALLATION
WARNING: To avoid electric shock, disconnect the test leads from any
Disconnect the test leads from the meter.
1. Remove the screws securing the rear cover using a Phillips head
screwdriver.
2. Lift the cover off and replace the battery observing the correct polarity.
3. Insert the new battery into the battery holder.
Replace the rear cover and secure with the screws. WARNING: To avoid
electric shock, do not operate the meter until the battery cover is in place
and fastened securely.
NOTE: If your meter does not work properly, check the fuses and battery to
make sure that they are still good and that they are properly inserted.
OPERATING INSTRUCTIONS
WARNING: Risk of electrocution. High-voltage circuits, both AC and DC, are
very dangerous and should be measured with great care.
1. ALWAYS turn the function switch to the OFF position when the meter is not
in use.
DC VOLTAGE MEASUREMENTS
CAUTION: Do not measure DC voltages if a motor on the circuit is being
switched ON or OFF. Large voltage surges may occur that can damage
the meter.
1. Set the function switch to the highest V DC position.
2. Insert the black test lead banana plug into the negative
(COM) jack.
Insert the red test lead banana plug into the positive (V)
jack.
3. Touch the black test probe tip to the negative side of the
circuit.
Touch the red test probe tip to the positive side of the
circuit.
4. Read the voltage in the display. Reset the function
switch to successively lower V DC positions to obtain a
higher scale reading.
DC CURRENT MEASUREMENTS
1. Insert the black test lead banana plug into the negative
(COM) jack.
2. Set the function switch to the 250mA DC position and
insert the red test lead banana plug into the (mA) jack.
3. Remove power from the circuit under test, then open up
the circuit at the point where you wish to measure
current.
4. Touch the black test probe tip to the negative side of the
circuit.
Touch the red test probe tip to the positive side of the
circuit.
5. Apply power to the circuit.
6. Read the current in the display. Reset the function
switch to successively lower mA positions to obtain a higher scale reading.
AC VOLTAGE MEASUREMENT
WARNING: Risk of Electrocution. The probe tips may not be long enough
to contact the live parts inside some 240V outlets for appliances because
the contacts are recessed deep in the outlets. As a result, the reading may
show 0 volts when the outlet actually has voltage on it. Make sure the
probe tips are touching the metal contacts inside the outlet before
assuming that no voltage is present.
CAUTION: Do not measure AC voltages if a motor on the circuit is being
switched ON or OFF. Large voltage surges may occur that can damage
the meter.
1. Set the function switch to the highest V AC position.
2. Insert the black test lead banana plug into the negative
(COM) jack.
Insert red test lead banana plug into the positive (V)
jack.
3. Touch the black test probe tip to the negative side of
the circuit.
Touch the red test probe tip to the positive side of the
circuit.
4. Read the voltage in the display. Reset the function
switch to successively lower V AC positions to obtain a
higher scale reading.
RESISTANCE MEASUREMENTS
WARNING: To avoid electric shock, disconnect power to the unit under
test and discharge all capacitors before taking any resistance
measurements. Remove the batteries and unplug the line cords.
1. Set the function switch to the X10 or X1K position.
2. Insert the black test lead banana plug into the negative
(COM) jack
Insert the red test lead banana plug into the positive !
jack.
3. Touch the test probe tips together and adjust the OHM
Zero Adjust knob for a “0” reading.
4. Touch the test probe tips across the circuit or part under
test. It is best to disconnect one side of the part under
test so the rest of the circuit will not interfere with the
resistance reading.
5. Read the resistance on the scale
dB MEASUREMENTS
The dB scale can be used to measure the milliwatt power dissipation on a
600!load by measuring the voltage across a 600 !load. An AC voltage of
0.775Vrms across 600!is equal to 1mW or “0”dB When converting an AC
Voltage measurement to dB take the dB reading from the lowest arc on the
scale plate and then add the appropriate dB correction found in the table
below.
ACV ADD dB
10 0 -10 ~ 22
50 14 4 ~ 36
250 28 18 ~ 50
500 34 24 ~ 56
MAINTENANCE
WARNING: To avoid electric shock, disconnect the test leads from any
source of voltage before removing the back cover or the battery or fuse
covers.
WARNING: To avoid electric shock, do not operate your meter until the
battery and fuse covers are in place and fastened securely.
This MultiMeter is designed to provide years of dependable service, if the
following care instructions are performed:
1. KEEP THE METER DRY. If it gets wet, dry it immediately.
2. USE AND STORE THE METER IN NORMAL TEMPERATURES.
Temperature extremes can shorten the life of the electronic parts and
distort or melt plastic parts.

damage the electronic parts or the case.
4. KEEP THE METER CLEAN. Wipe the case occasionally with a damp
cloth. DO NOT use chemicals, cleaning solvents, or detergents.
5. USE ONLY FRESH BATTERIES OF THE RECOMMENDED SIZE AND
TYPE. Remove old or weak batteries so they do not leak and damage the
unit.
6. IF THE METER IS TO BE STORED FOR A LONG PERIOD OF TIME,
the batteries should be removed to prevent damage to the unit.
UL LISTED
The UL mark does not indicate that this product has been evaluated for the
accuracy of its readings.
