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.
• Do not open the meter to replace batteries while the probes are connected.
• 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.
• Do not hold meter above hand & finger guard during use.
• 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.
• Usage of this meter in any way other than that specified by the
manufacturer can impair safe operation, resulting in severe injury or death.
