Important Safety Information
Electric shock hazard:
• Do not expose this unit to rain or moisture.
• Do not use this unit if it is wet or damaged.
• Only use the test leads provided with the equipment or UL Listed Probe Assembly with
same rating or better.
• Inspect the test leads or accessory before use. They must be clean and dry, and the
insulation must be in good condition. Do not use the test lead 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.
Electric shock hazard:
• 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 precautions may result in injury and can damage the instrument.
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.
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.
