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.

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.
3.
HANDLE THE METER GENTLY AND CAREFULLY.
Dropping it can
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.
TROUBLESHOOTING
There may be times when your meter does not operate properly. Here are
some common problems that you may have and some easy solutions to them.
Meter Does Not Operate:
1. Always read all the instructions in this manual before use.
2. Check to be sure the battery is properly installed.
3. Check to be sure the battery is good.
