Explanation
Memory storage symbol
—
EG-4P: The EG-4P model displays the total memory
storage remaining in hours and minutes. For example, if it
displays the memory symbol 181:50 this represents
181 hours and 50 minutes of memory storage remaining on
the dosimeter.
Calendar symbol
—The calendar symbol and calendar field
displays the day-month-year
Battery power clock symbol

Dosimeter Measurement Descriptors/Variants
Descriptors Variants
Lmax
variants Sound pressure level
—is the basic measure of noise
loudness, expressed in decibels. (In DMS this is noted
as
“SPL”)
L
ASMX
Maximum sound level
—is the highest sound level
recorded during a measurement interval with a particular
response setting (Slow or Fast) and weighting (A or C).
L
MAX
is the highest value that is included in Lavg or dose
calculations.

Under OSHA regulations, unprotected workers may not
be exposed to maximum sound levels greater than
115 dB, measured with a Slow response rate.
Lcpk Peak Level
—is the highest instantaneous sound pressure
level recorded during a measurement interval. Unlike the
maximum level, the peak is detected independently of
dosimeter settings for response rate or weighting.

Under OSHA regulations, unprotected workers may not
be exposed to peak sound levels greater than 140 dB.
L
ASMN
Minimum sound level
—The lowest sampled sound level
during the measurement
interval allowing for the unit’s
Response Time setting (Fast or Slow).
