Read these operating instructions thoroughly and
completely before operating your meter. Pay
particular attention to WARNINGS, which will
inform you of potentially dangerous procedures.
Follow the instructions in these warnings.
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.
Always be 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.
