Additional Information
  • Read, understand and follow all warnings and instructions before operating testers.
  • Do not attempt to measure insulation resistance, resistance or continuity on live circuits.
  • Before each use, verify meter operation by measuring known voltage.
  • Do not use meter during electrical storms or in wet weather.
  • Use only CAT III/CAT IV safety rated test leads. Do use the meter if test leads appear to be damaged.
