Making Maximum Measurements; Level Indications - Radio Shack 33-2055A Owner's Manual

MAKING MAXIMUM
MEASUREMENTS
To measure the continuous maximum
sound level, follow the steps in "Making
Normal Measurements" on Page 10 and
press so MAX appears on the dis-
MAX
play.
The meter displays only the loudest mea-
sured sound level during the 1-second
sampling period. The bargraph shows the
maximum level of every 0.2 or 0.5 sec-
onds. The bargraph segment that corre-
sponds to the peak reading stays on the
display for 2 seconds or until the meter
measures a higher maximum level.
Press MAX again to cancel the continu-
ous maximum measurement and resume
a normal continuous average measure-
ment.

LEVEL INDICATIONS

The meter displays the sound level using
numbers and a bar graph. The numbers
show the sound level in dB within 10 dB
of the selected range and the meter up-
dates the reading once per second.
