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 Limits
Function
V DC, V AC
mA AC/DC
A AC/DC
Frequency, Resistance,
Capacitance, Diode, Continuity
Maximum Input
1000V DC/AC rms
400mA AC/DC

BATTERY INSTALLATION
BATTERY INSTALLATION
WARNING: To avoid electric shock, disconnect the test
leads from any source of voltage before removing the battery
cover.
1. Turn power off and disconnect the test leads from the
meter.
2. Open the rear battery cover by removing two screws (B)
using a Phillips head screwdriver.
3. Insert the battery into battery holder, observing the correct
polarity.
4. Put the battery cover back in place. 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 batteries to make sure that they are still good and
that they are properly inserted.
9
REPLACING THE FUSES
WARNING: To avoid electric shock, disconnect the test
leads from any source of voltage before removing the fuse
cover.
1. Disconnect the test leads from the meter.
2. Remove the battery cover (two “B” screws) and the battery.
3. Remove the six “A” screws securing the rear cover.
4. Gently remove the old fuse and install the new fuse into
the holder.
5. Always use a fuse of the proper size and value
(0.5A/1000V fast blow for the 400mA range [SIBA 70-17240], 10A/1000V fast blow for the 20A range [SIBA 50-19906]).
6. Replace and secure the rear cover, battery and battery
cover.
WARNING: To avoid electric shock, do not operate your

OPERATING INSTRUCTIONS
WARNING: Risk of electrocution. High-voltage circuits,
both AC and DC, are very dangerous and should be
measured with great care.
NOTES:
1. ALWAYS turn the Function switch to the OFF position
when the meter is not in use.
2. If “ 1 ” appears in the display during a measurement, the
value exceeds the range you have selected. Change to a
higher range.
DC VOLTAGE MEASUREMENTS
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.
1. Set the function switch to the VDC or mVDC
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.
11
AC VOLTAGE (FREQUENCY, DUTY CYCLE)
MEASUREMENTS
WARNING: Risk of Electrocution. The probe tips may not
be long enough to contact the live parts inside some 240V

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 VAC position.
2. Insert the black test lead banana plug into
the negative COM jack.
Insert red test lead banana plug into the

longer than 30 seconds. Exceeding 30 seconds may
cause damage to the meter and/or the test leads.
1. Insert the black test lead banana plug into
the negative COM jack.
2. For current measurements up to 4000µA
DC, set the function switch to the µA
position and insert the red test lead
banana plug into the µA/mA jack.
3. For current measurements up to 400mA
DC, set the function switch to the mA
position and insert the red test lead

6. Read the capacitance value in the display
position.
Note: Upon entering the capacitance mode and
with no component connected, the meter will autorange to
the 0.000nF range. This is not a measurement range, but
is used to establish a zero reference.

AUTORANGING/MANUAL RANGE SELECTION
When the meter is first turned on, it automatically goes into
Autoranging. This automatically selects the best range for
the measurements being made and is generally the best
mode for most measurements. For measurement situations
requiring that a range be manually selected, perform the
following:
1. Press the RANGE key. The “Auto” display indicator will
turn off.
2. Press the RANGE key to step through the available
ranges. Observe the decimal point and units displayed
until the preferred range is located.
3. To exit the Manual Ranging mode and return to
Autoranging, press and hold the RANGE key for 2
seconds.
Note: Manual ranging does not apply for the Capacitance
and Frequency functions or for the mV range.
18
RELATIVE MODE
The relative measurement feature allows you to make
measurements relative to a stored zero reference value. A
reference voltage, current, etc. can be stored and
measurements made in comparison to that value. The
displayed value is the difference between the reference
value and the measured value.
1. Perform the measurement as described in the operating
instructions.
2. Press the REL button to store (zero) the reading in the
display and the "REL" indicator will appear on the display.
3. The display will now indicate the difference between the
stored value and the measured value.
4. Press the REL button to exit the relative mode.
Note: The Relative function does not operate in the
Frequency function.
DISPLAY BACKLIGHT
Press the backlight
button for >2 second to turn on.
Press the button again to turn the backlight off.
HOLD
The hold function freezes the reading in the display. Press
the HOLD key momentarily to activate or to exit the HOLD
function.
AUTO POWER OFF
The auto off feature will turn the meter off after 30 minutes.
To disable the auto power off feature, hold down the MODE
button and turn the meter on.
LOW BATTERY INDICATION
The icon will appear in the display when the battery
voltage becomes low. Replace the battery when this
appears.

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, wipe it off.
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.

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.
20
REPLACING THE BATTERY
WARNING: To avoid electric shock, disconnect the test
leads from any source of voltage before removing the
battery door.

operating voltage, the low battery icon will appear in the
lower left of the LCD display. The battery should be
replaced.
2. Follow instructions for installing the battery. See the
Battery Installation section of this manual.
3. Dispose of the old battery properly.
WARNING: To avoid electric shock, do not operate your
meter until the battery door is in place and fastened
securely.
