Customizing set-up parameters in DMS
Display setting
24
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.)

Display setting
The display screen is used to customize the parameters which will appear on your Edge. It is organized by two columns, the “Display
position” and the “Item to Display” and includes a “Set selected Items” selection/drop down box. The display position indicates the order
of the parameter (or item) which will appear on the display, while the “Item to display” designates the measurement or parameter. The
example/figure below displays the SPL, Max, Min, Lavg, TWA, Dose, UL, RT, and battery time remaining parameters to appear on the
display. (Note: There are up to 18 selectable parameters. Off indicates no item will appear.)
1.
Click on the
Display
tab from the Edge’s Instrument Configuration panel (see 1). To customize the display, click on either the
