To ensure safe operation and service of the meter, follow these instructions.
Failure to observe these warnings can result in severe injury or death.
• Before each use verify meter operation by measuring a known voltage
or current.
• Never use the meter on a circuit with voltages that exceed the category
based rating of this meter.
• Do not use the meter during electrical storms or in wet weather.
• Do not use the meter or test leads if they appear to be damaged.
• Use only with CAT III or CAT IV rated test leads.
• Ensure meter leads are fully seated, and keep fingers away from the
metal probe contacts when making measurements.
• Use caution when working with voltages above 25V AC RMS or 60V DC.
Such voltages pose a shock hazard.
• To avoid false readings that can lead to electrical shock, replace batteries
when a low battery indicator appears.
• Do not attempt to measure resistance or continuity on a live circuit.
• 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.
• To avoid risk of electric shock, disconnect leads from any voltage source
before removing battery door.
• To avoid risk of electric shock, do not operate meter while battery door is removed.
