WARNINGS
• 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 test leads are fully seated into jacks, and keep fingers away
from the metal probe contacts when making measurements.
• 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.
• 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.
• To avoid risk of electric shock, disconnect leads from any voltage
source before removing battery door.
• To avoid risk of electric shock, do not operate meter while
battery door is removed
