If you get an overrange indication, change
the range setting until you get a reading in
the upper half of the range (0 to + 10 dB).
Notes:
• The underrange or overrange indica-
tion can also appear when you recall
a measurement using data hold and
the measurement is under or over the
selected range. See "Using Data
Hold."
• The meter cannot measure sound
levels lower than 50 dB or higher than
126 dB.
