PRECAUTIONS

WARNING: Measure known voltage with the meter to verify that the meter is working properly. If the meter is working abnormally, stop using it immediately. A protective device may be damaged. If there is any doubt, have the meter inspected by a qualified technician.
WARNING: Do not use the meter or test leads if they look damaged. Check to see if the test wire has insulation damage or bare metal. Check test wire continuity. If the wire is damaged, replace it with a new one before using the meter.
WARNING: When testing voltage that exceeds 30V AC or 60V DC, be particularly careful to avoid electric shock.
WARNING: When measuring, use the correct jack, and select the proper function and measuring range.
WARNING: When making connections, connect the common test lead before connecting the live test lead. When disconnecting, disconnect the live test lead before disconnecting the common test lead.
WARNING: Do not use it under direct sunlight or high temperatures.
WARNING: Disconnect power to the circuits and discharge all high-voltage capacitors before testing resistance, continuity, diodes, or capacitance.
WARNING: Before measuring the current, check the meter’s fuse and turn off power to the circuit before connecting the meter to the circuit.
WARNING: Do not measure voltages exceeding the rated voltage marked on the meter.
WARNING: Do not operate the meter with any part removed or damaged.
WARNING: When the battery’s low voltage indicator illuminates, replace the battery immediately. A low battery will cause meter reading errors and may result in electric shock or personal injury.
WARNING: Do not operate the meter around explosive gas, vapor, or dust.
CAUTION: Pay attention to the battery polarity when changing the battery.
CAUTION: When maintaining the meter, use replacement parts specified by the factory.
CAUTION: To avoid damage to the meter, do not exceed the maximum limits of the input values shown in the Specification tables.
CAUTION: Before changing functions, disconnect the test leads from the circuit under test.
NOTE: Keep your fingers behind the protection guards while measuring.

Operation

Completing an AC or DC voltage measurement

CAUTION : To avoid electrical shock and/or damage to the meter, do not attempt to take any voltage measurement that might exceed 300V DC or AC rms.
CAUTION: Do not measure AC/DC voltages if a monitor on the circuit is being switched ON or OFF. Large voltage surges may occur that can damage the meter.

• Set the switch (B) to the AC (1) or DC (2) position.
• Connect the black test lead (F) to the common jack (C) and the red test lead (E) to the positive jack (D).
• Connect the test leads (E and F) to the circuit being measured.
• Read the value on the LCD display (A). The polarity of the red test lead (E) connection will be indicated when making a DCV measurement.

Completing a resistance measurement

WARNING: To avoid damage to the meter or equipment being measured, cut off all power supply to the measured circuits and discharge all high voltage capacitors before measuring resistance.

• Set the switch (B) to the Ω position (1).
• Connect the black test lead (F) to the common jack (C) and the red test lead (E) to the positive jack (D).
• Connect the test leads (E and F) to the circuit being measured.
• Read the measured resistance value on the display (A).

Completing a diode measurement WARNING: To avoid damage to the meter or equipment being measured, cut off all power supply to the measured circuits and discharge all high voltage capacitors before measuring the diode.

• Set the switch (B) to the diode position (1).
• Connect the black test lead (F) to the common jack (C) and the red test lead (E) to the positive jack (D).
• Separately connect the black test lead (F) and the red test lead (E) to the negative pole and positive pole of the measured diode.
• Display (A) shows the forward bias value of the measured diode. If the poles of the test leads are connected inversely, the meter displays “OL”.

Testing a battery

WARNING: To prevent injury or damage to the meter, do not connect the meter to a battery with a voltage rating that exceeds 60V AC or 30V DC.

• Set the switch (B) to either the 9V (1) or 1.5V (2) battery position (1).
• Connect the black test lead (F) to the common jack (C) and the red test lead (E) to the positive jack (D).
• Connect the red test lead (E) to the positive (+) end and the black test lead (F) to the negative (-) end of the battery. Read the measurement on the display (A).

Maintenance

WARNING: Before you open the meter, always disconnect it from all sources of electrical current and make sure you are not charged with static electricity, which may destroy the internal components.
WARNING: To avoid injury or damage to the meter, do not wet the inner parts of the meter. Before opening the battery cover, remove the connecting cable between the test probe and the input signal.
WARNING: Any adjustment, maintenance, or repair work carried out on the meter while it is life should be carried out by a qualified electrician.

WARNING: When you open the meter, remember that some internal capacitors can retain a dangerous voltage level even after the instrument is switched off.
CAUTION: If the meter is not going to be used for a long time, take out the battery and do not store the meter in a high temperature or high humidity environment.

REPLACING THE BATTERY AND FUSE

WARNING : To prevent electrical hazard or shock, turn off the meter and disconnect the test leads and any input signals before removing the battery cover.
WARNING : Change the battery when the battery symbol appears on the LCD in order to avoid incorrect data, which could lead to electric shock or personal injury.
CAUTION: Only use the specified batteries and fuses for replacement. See the Product Specifications section of this manual for more information.
CAUTION: Do not mix old and new batteries. Do not mix alkaline, standard (carbon-zinc), or rechargeable (ni-cad, ni-mh, etc) batteries.

• Turn the meter off by turning the switch to the OFF position.
• Disconnect the test leads and any connectors from the terminals on the meter.
• Use a screwdriver to unscrew and remove the battery cover located on the back of the meter. If you are replacing the fuse, unscrew all of the screws on the back of the meter.
• Remove the used batteries or damaged fuse.
• Replace with a new battery or fuse.
• Reattach the battery cover and secure with the screws.

TEST LEAD REPLACEMENT
Replacement test leads must meet the manufacturer’s specifications (EN 610 10-031 standard, CAT III 600V 10A, or better).

Care and Cleaning

• Periodically wipe the meter with a damp cloth and mild detergent.
• Do not use abrasives or solvents.
• Dirt or moisture in the terminals can affect readings.

To clean the terminals:

• Turn the meter off and remove all test leads.
• Shake out any dirt that may be in the terminals.
• Soak a new cotton swab with a cleaning and oiling agent (such as WD-40).
• Work the swab around in each terminal. The oiling agent insulates the terminals from moisture-related contamination.
