WARNING

Read and understand this material before operating or servicing this equipment. Failure to understand how to safely operate this tool could result in an accident causing serious injury or death.

WARNING

Electric shock hazard: Contact with live circuits could result in severe injury or death.

Important Safety Information

WARNING

Electric shock and fire hazard:

• Do not expose this unit to rain or moisture.
• Do not use the unit if it is wet or damaged.
• Use test leads or accessories that are appropriate for the application. Refer to the category and voltage rating of the test lead or accessory.
• Inspect the test leads or accessory before use. They must be clean and dry, and the insulation must be in good condition. Destroy test leads and replace immediately if the contrasting inner layer of insulation is visible.
• Use this unit for the manufacturer's intended purpose only, as described in this manual. Any other use can impair the protection provided by the unit.

Failure to observe these warnings could result in severe injury or death.

WARNING

Electric shock hazard:

• The test leads supplied with this product comply with IEC 61010-031:2008, UL 61010-031:2010 and CAN/CSA-C22.2 NO. 61010-031A-07–Amendment 1:2010. These safety standards limit the exposed length of the probe tip to 4 mm for measurement categories III and IV. These test leads include a cap that must be in place when used in measurement category III or IV applications.
• Do not apply more than the rated voltage between any two input terminals, or between any input terminal and earth ground.
• Do not contact the test lead tips or any uninsulated portion of the accessory.
  Failure to observe these warnings could result in severe injury or death.

WARNING

Electric shock hazard:

• Do not operate with the case open.
• Before opening the case, remove the test leads from the circuit and shut off the unit.

Failure to observe these warnings could result in severe injury or death.

Important Safety Information

WARNING

Electric shock hazard:

The fuses are an integral part of the overvoltage protection. When fuse replacement is necessary, refer to “Specifications” for the correct type, size, and capacity. Using any other type of fuse will void the overvoltage protection rating of the unit.

Failure to observe this warning could result in severe injury or death.

WARNING

Electric shock hazard:

• Unless measuring voltage, current, or frequency, shut off and lock out power. Make sure that all capacitors are discharged. Voltage must not be present.
• Set the selector and connect the test leads so that they correspond to the intended measurement. Incorrect settings or connections can result in a blown fuse.
• Using this unit near equipment that generates electromagnetic interference can result in unstable or inaccurate readings.

Failure to observe these warnings could result in severe injury or death.

CAUTION

Electric shock hazard:

Do not change the measurement function while the test leads are connected to a component or circuit.

Failure to observe this precaution may result in injury and can damage the unit.

CAUTION

Electric shock hazard:

• Do not attempt to repair this unit. It contains no user-serviceable parts.
• Do not expose the unit to extremes in temperature or high humidity. Refer to “Specifications.”
  Failure to observe these precautions may result in injury and can damage the unit.
