Under Range Condition
An under range condition occurs when the noise source is more than 0.1dB
below the bottom of the range selected, at which point an under range indicator
will flash on the display of your meter. In such circumstances it is highly
recommended to change to a higher range with a higher sensitivity (i.e. more
gain) as your meter will be out of specification.
The under range indicator will flash for a minimum of one second or while the
under range condition remains.
Where the noise source is more than 0.5dB below the bottom of the selected
range, no value or under range warning is displayed.
Note: Under range displayed on your meter indicates that you should discard the
measurements, select a lower range and re-take your measurements.
