Dosimeter settings for the Edge
Name Field
*Note: refer to Glossary for more detailed information.
Heartbeat enable
When enabled (or checked), the LED will flash green while running
and flash amber when stopped.
Response
Either Slow Time Response or Fast Time Response is applied to
the measurements. (Typically Slow time response is used in the
US market while Fast is used in the EU communities.)
C-A enable
When enabled (or checked), C minus A will be calculated.
Projected Time
A selectable time parameter via the up/down arrows or type in a
value. The projected time value is used to make projected dose
calculation for the dose measurement.
Peak Weighting
Select either A, C or Z for the peak frequency weighting.
Dose indicator LED
When enabled (or checked), the LED will flash red when the dose
value exceeds the designated entered value.
Setup name
(Optional field) A setup name may be entered into the Meter 1
and/or Meter 2 fields. When set, it appears on the top of Edge’s
display (example setup names: OHSHA, MSHA, EU directive).
Threshold enable
When the checkbox is selected and a value is entered for meter 1
and/or meter 2, the threshold is used to calculate Lavg, TWA, and
Dose measurements.
Upper Limit
Select a UL dB level by the up/down arrows or by typing in a value.
(Note: The upper limit (UL) is a measurement setting in which the
user selects a specific decibel level. The UL value records the
amount of time that the Sound level is at or greater than the
entered level.)
RMS Weighting
Select either A or C RMS Weighting. (Note: The RMS (root mean
square) are the results from the Edge with the response time and
weighting settings taken into account.)
Criterion Level
Select a Criterion level via the up/down arrow or by typing in a
value. (Note: Criterion level is the average SPL that will result in
100% dose over the criterion time and is typically set by a
regulatory agency such as OSHA, EU directive.)
Exchange Rate
Enter in (or select with up/down arrows) 3, 4, or 5 dB. ER refers to
how sound energy is averaged over time. (OSHA uses a 5 dB
doubling rate while most of the world uses 3 dB.)
