• Keep the manual at hand to enable quick reference whenever necessary.

• The instrument is to be used only in its intended applications.

• Understand and follow all the safety instructions contained in the manual.

• It is essential that all safety instructions are adhered to.

• Failure to follow the safety instructions may cause injury, instrument damage

The symbol indicated on the instrument means that the user must refer to the related parts in the manual for safe operation of the instrument. It is essential to read the instructions wherever the symbol appears in the manual.

DANGER is reserved for conditions and actions that are likely to cause serious or fatal injury.

WARNING is reserved for conditions and actions that can cause serious or fatal injury.

CAUTION is reserved for conditions and actions that can cause injury or instrument damage.

DANGER

• Never make measurement on a circuit in which voltage over 600V exists.

• Do not exceed the CAT rating of the measuring device

• Do not attempt to make measurement in the presence of flammable gases. The use of the instrument may cause sparking, which can lead to an explosion.

• Transformer jaw tips are designed to not short the circuit during a test. If equipment under test has exposed conductive parts extra precaution should be taken to minimize the possibility of shorting.

• Never use the instrument if its surface or your hand is wet.

• Do not exceed the maximum allowable input of any measuring range.

• Never open the battery cover during a measurement.

• The instrument is to be used only in its intended applications or conditions. Use in other than as intended may cause instrument damage or serious personal injury.

Page 3

WARNING

• Never attempt to make any measurement if any abnormal conditions are noted, such as broken case, cracked test leads and exposed metal part.

• Do not turn the function selector switch with plugged in test leads connected to the circuit under test.

• Do not install substitute parts or make any modification to the instrument. Return the instrument to your distributor for repair or recalibration.

• Do not try to replace the batteries if the surface of the instrument is wet.

• Always switch off the instrument before opening the battery compartment cover for battery replacement.

CAUTION

• Set the Function Switch to an appropriate position before starting measurement.

• Firmly insert the test leads.

• Disconnect the test leads from the instrument for current measurement.

• Do not expose the instrument to the direct sun, high temperature and humidity or dewfall.

• Be sure to power off the instrument after use. When the instrument will not be in use for a long period, place it in storage after removing the batteries.

• Use only a soft cloth dampened with water or neutral detergent for cleaning the meter. Do not use abrasives, solvents or harsh chemicals. Allow to dry thoroughly before use.

Measurement categories (Over-voltage categories)

To ensure safe operation of measuring instruments, IEC61010 establishes safety standards for various electrical environments, specified as CAT I through CAT IV, and called measurement categories. Higher-numbered categories correspond to electrical environments with greater momentary energy, so a measuring instrument designed for CAT III environments can endure greater momentary energy than one designed for CAT II.

• CAT I: Secondary electrical circuits connected to an AC electrical outlet through a transformer or similar device.

• CAT II: Primary electrical circuits of equipment connected to an AC electrical outlet by a power cord.

• CAT III: Primary electrical circuits of the equipment connected directly to the distribution panel, and feeders from the distribution panel to outlets.

• CAT IV: The circuit from the service drop to the service entrance, and to the power meter and primary over current protection device (distribution panel).

4-2. Check the battery voltage

Start with the dial in the “OFF” position then rotate the dial to any position. Confirm that the low battery symbol is not displayed on the LCD screen. If the low battery symbol is displayed follow the instructions in Section 7, Battery Replacement. (It is important to start from the "Off" position to ensure that a blank screen is not due to the auto off feature.)

4-3. Check the battery cover

The battery cover must be in place and securely fastened before powering on the meter or connecting test leads to a circuit. See Section 7, Battery Replacement

4-4. Check test lead condition, continuity and rating

Do not use damaged test leads. Examine the test leads for worn or cracked insulation. Check test lead continuity. Do not use test leads in applications that exceed their CAT rating. Check the CAT rating of the test lead and refer to Figure 3.

4-5. Checking the switch setting & operation

Confirm the dial is set to the correct position for the measurement function being performed. Confirm that the symbols displayed on the LED screen match the measurement function. (Refer to Figure 2). Ensure that the Data Hold feature is disabled.
