2.25 Do not use meter in condensing atmospheres. That is, do
not use meter in conditions where ambient temperature and
humidity could cause condensation of water inside of meter.
Doing so may cause injury to the user.
2.26 Do not use the meter if either the meter or the test leads are
wet, either from exposure to the weather, or after cleaning
the case of the meter. Doing so may cause injury to the user.
2.27 Do not attempt immediate use of the meter when bringing
it from a cold environment to a warm environment.
Condensation of water, inside and outside of the meter, may
produce dangerous measuring conditions. Allow the meter
to warm to room temperature before using. Failure to
observe this precaution may result in damage to the meter
or injury to the user.
2.28 Do not modify the meter. Changing the design may make
the meter unsafe and may result in injury to the user.
2.29 Use caution when attempting to evaluate if a dangerous
voltage is present. The meter will not read AC voltage if it
is set to DC, nor will it read DC if it is set to AC.
For example, if the meter is set to 200VDC, it will not
measure a dangerous AC voltage, even if the probes are
