Read Instruction Manual

Power tools that are no longer usable should not be 

disposed of with household waste but in an environmentally 

friendly way. Please recycle where facilities exist. Check 

with your local council authority for recycling advice.

Recycling packaging reduces the need for landfill and raw 

materials. Reuse of recycled material decreases pollution in 

the environment. Please recycle packaging where facilities 

exist. Check with your local council authority for recycling 

advice.

WARNING!

 

The appliance is not to be used by persons (including children) 

with reduced physical, sensory or mental capabilities, or lack of experience and 

knowledge, unless they have been given supervision or instruction.

Young children should be supervised to ensure that they do not play with the appliance.

1.  Do not store or use the tool and battery pack in locations where the temperature may reach or 

exceed 40

0

C (such as inside sheds or metal buildings in summer).

2.  Do not incinerate the battery pack even if it is seriously damaged or is completely worn out. 

The battery can explode in a fire.

WARNING: 

To avoid risk of personal injury and/or possible damage to the 

meter or to the equipment under test, follow these guidelines: If these guidelines 

are not followed there is risk of shock. Read and understand all instructions 

before using product.

•  CAT III – This measurement Category III multimeter is for use on permanently installed 

loads. Examples are measurements on distribution boards, circuit breakers, wiring and 

equipment like fixed installation motors.

•  Do not use the meter for measurements higher than Category III 300V 10A.
•  DO NOT use the meter if it is damaged. Before using the meter, inspect the case. Pay 

particular attention to the insulation surrounding the connectors.

•  ALWAYS Inspect the test leads for damaged insulation or exposed metal. Check the test 

leads for continuity. Replace damaged test leads before you use the meter.

•  DO NOT use the meter if it operates abnormally. Protection may be impaired.
•  DO NOT operate the meter where explosive gas, vapor, or dust is present.
•  DO NOT apply more than the rated voltage, as marked on the meter, between terminals or 

between any terminal and earth ground.

•  ALWAYS verify the meter’s operation by measuring a known voltage before use.
• 

ALWAYS turn off circuit power before connecting the meter in the circuit to measure current. 

Remember to place the meter in series with the circuit.

• 

ALWAYS turn off circuit power before connecting the meter to the circuit to measure 

resistance.

•  ALWAYS Use caution when working with voltage above 30V AC rms, 42V peak, or 60V DC. 

These voltages pose an increased shock hazard.

• 

ALWAYS keep your fingers behind the finger guards on the probes when in use.

•  ALWAYS connect the common test lead before you connect the live test lead. When you 

disconnect test leads, disconnect the live test lead first.

•  ALWAYS Remove the test leads from the meter before you open the battery cover or the 

case.

•  DO NOT operate the meter with the battery cover or portions of the case removed or 

loosened.

•  ALWAYS replace the battery as soon as the low battery indicator (            ) appears. Failure 

to do so could lead to possible electric shock or personal injury due to false readings.

•  DO NOT touch any conductor with hand or skin, and do not ground yourself.
• 

DO NOT use the meter in a manner not specified by this manual or the safety features 

provided by the meter may be impaired.

•  DO NOT operate this instrument if your hand, a test lead or the instrument is wet.
•  ALWAYS Adhere to local and national safety codes. Personal protective equipment must 

be used to prevent shock and arc blast injury where hazardous live conductors are exposed.

•  ALWAYS be aware that when an input terminal is connected to a hazardous live voltage, 

this potential can occur at all other terminals.

• 

ALWAYS use only 9 V batteries specified for use with this product. Use of any other 

batteries may create a risk of fire.

• 

DO NOT disassemble, service or repair this product. Repairs performed by unqualified 

personnel could result in serious injury.

•  DO NOT splash or immerse the unit in water.
• 

ALWAYS turn off the product when not in use.

•  ALWAYS ensure battery is inserted in the correct manner, with the correct polarity.
•  NEVER intentionally short any battery terminals.
•  DO NOT attempt to charge alkaline batteries.
• 

DO NOT dispose of batteries in fire.

•  ALWAYS remove the battery if storing the unit for over a month.
•  DO NOT dispose of this product with household waste.
•  ALWAYS check local codes and properly dispose of used batteries.
•  PLEASE RECYCLE in line with local provisions for the collection and disposal of electrical 

and electronic waste.

•  Disconnect circuit power and discharge all capacitors before testing resistance, diode, 

continuity and temperature.

•  Use the properly rated terminals (function and range) for your measurements. The terminals 

included with this multimeter are CAT III rated for 300V 10A Max.

•  Before turning the rotary switch to change functions, disconnect test leads from the circuit 

under test
