Explanation
Memory storage symbol
–
eg5:
The eg5 model displays the total memory storage remaining in hours and
minutes. For example, if it displays the memory symbol 100:50 this represents 100
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
– The battery power clock symbol identifies the number of hours
and minutes of battery time remaining on the dosimeter. (Note: refer to page iii to view battery
care and best practices.)

Edge Measurement descriptors/variants
The following is an explanation of the Edge descriptors and equivalents for Lmax, Lmin, and Lcpk.
Descriptors
Variants
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 L
AVG
or dose calculations.
Under OSHA regulations, unprotected workers may not be exposed to maximum
sound levels greater than 115dB, measured with a Slow response rate.
L
APK
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 140dB.
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).
