Additional Information
Warnings
  • Never use the meter on a circuit with voltages that exceed the category based rating of this meter.
  • Read, understand and follow all instructions, cautions and warnings attached to and /or packed with all test and measurement devices before each use.
  • Do not use the meter during electrical storms or in wet weather, and do not use the meter or test leads if they appear to be damaged.
  • Before each use verify meter operation by measuring a known voltage or current.
  • Always adhere to local and national safety codes. Use personal protective equipment to prevent shock and arc blast injury where hazardous live conductors are exposed.
