WARNINGS
To ensure safe operation and service of the tester,
follow these instructions. Failure to observe these
warnings can result in severe injury or death.
• 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.
• 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
60V DC or 25V AC RMS. Such voltages pose a
shock hazard.
• To avoid false readings that can lead to electrical
shock, replace batteries when a low battery
indicator appears.
• Unless measuring voltage, shut off and lock out
power before measuring resistance.
• Always adhere to local and national safety codes.
Use individual protective equipment to prevent
shock and arc blast injury where hazardous live
conductors are exposed.
• The MM500A is sealed to meet IP67 certification.
There are no user serviceable parts.
