Safety Precautions
Follow all safety and operating instructions to ensure maximum
personal safety during the operation and to ensure the meter is
used safely and is kept in good operating condition.
•
Read these operating instructions thoroughly and completely
before operating your meter. Pay particular attention to
WARNINGS, which will inform you of potentially dangerous
procedures. The instructions in these warnings must be followed.
• Always inspect your meter and test leads for any sign of
damage or abnormality before every use. If any abnormal
conditions exist (i.e. broken test leads, cracked cases, display
not reading, etc.), do not attempt to take any measurements.
• Do not expose the instrument to direct sunlight, extreme
temperature or moisture.
•
Never ground yourself when taking electrical measurements.
Do not touch exposed metal pipes, outlets, fixtures, etc., which
might be at ground potential. Keep your body isolated from
ground by using dry clothing; rubber shoes, rubber mat, or any
approved insulating material.
• You always are careful when working with voltages above 60V
dc or 30V ac rms. Keep fingers behind the probe barriers while
measuring.
• Never use the meter to measure voltages that might exceed
the maximum allowable input value of any function.
• Never touch exposed wiring, connections or any live circuit
when attempting to take measurements.
