WARNINGS
To ensure safe operation and service of the tester, follow these instructions.
Failure to observe theses 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 or fuses 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.
