2.41 To avoid damage to the meter and possible user injury,
disconnect test leads from test points before changing the
function/range. Failure to observe this precaution may result
in damage to the meter or injury to the user.
2.42 Avoid usage near strong magnetic fields (magnets,
loudspeakers, transformers, motors, coils, relays,
contactors, electromagnets, etc.). The meter may display
readings that are in error, causing the user to misinterpret
the hazards present. For example, the meter may indicate a
low voltage when high voltages are actually present. Failure
to observe this precaution may result in damage to the meter
or injury to the user.
2.43 Avoid usage near strong electrostatic fields (high voltage
power lines, televisions, computer monitors, etc.).
The meter may display readings that are in error, causing
the user to misinterpret the hazards present. For example,
the meter may indicate a low voltage when high voltages
are actually present. Failure to observe this precaution may
result in damage to the meter or injury to the user.
