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.
• 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.
• 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 if a low battery indicator appears.
• Unless measuring voltage or current, shut off and lock out
power before measuring resistance or capacitance.
• 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.
