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 IV rated test leads.
• Ensure meter leads are fully seated, and keep fingers away from the
metal probe contacts when making measurements.
