The Edge Personal Noise Dosimetry

QUICK START

GUIDE

Edge Display and Keypad

Turning on

1. Turn on the Edge by pressing and releasing the key.

Resetting

Resetting (or clearing the data) is performed by either using the TSI Quest Detection Management

Software DMS when downloading or setting up parameters. Another option is from the Edge’s shortcut

reset menu.

+ To reset from the keypad ensure the Edge is o, then:

1. Press key.

2. Press and hold and keys when the splash

screen appears. The shortcut menu will appear

(see right).

3. Press the up arrow until the reset icon is selected.

4. Press and hold the key until it shows the les

were deleted.

A 3, 2, 1 countdown and a shaded bar indicates reset.

5. To exit, press down arrow until icon is selected. Press key.

Calibrating

A calibration may be performed before and/or after a dosimetry test.

1. Remove the windscreen while the Edge is turned on and stopped.

2. Slide the Edge into the cavity of the calibrator, ensuring the

adapter ring is inserted into the calibrator.

3. Turn on the calibrator. Set the calibrator to 114 dB and 1000 Hz

(if applicable).

4. “CAL” will ash on the Edge display automatically detecting the

calibration screen.

5. Press the key to trigger the calibration screen.

6. To adjust the calibration value on the display, repeatedly press the

up/down arrows to match 114.0 dB.

7. Press key to exit.

Viewing and/or navigating data

1. Press the up/down arrow keys to navigate through the

measurements and parameters.

Setting up the Edge

All the Edge parameters are setup via TSI QuestDetection Management Software DMS in the Instrument

Communication panel or button from the DMS start screen.

Running a study

1. Once the Edge is turned on, press and hold the button.

+ A 3, 2, 1 countdown will appear. Then, a run indicator will appear on the top of the display.

Also the LED will ash green unless this was disabled in the DMS via the heartbeat eld.

Ending a study

1. While running a study, press and hold the run/stop button.

+ A 3, 2, 1 countdown will appear and the indicator will appear on the top of the display.

Turning o

1. Press and hold the on/o enter button for the count down.

Screen Indicators:

in run mode

Charging

When the battery is fully discharged, allow approximately 3 to 4 hours to recharge your Edge.

Tip: to quickly check battery power remaining on the Edge, press the up/down arrow key to view the

battery power symbol and hours on the display.

(See user manual for customizing display if it does not appear.)

1. To charge, plug in the power adapter to the EdgeDock.

+ The EdgeDock’s lower LED will appear solid amber when powered on.

2. Slide the Edge downward onto the hook of the EdgeDock until it clicks. It should be fully seated.

+ The top LED will appear as red ashing if charging or solid green when fully charged.

Battery Power: 48 hours and 52 minutes remaining

Power Adapter

Charging Status: Upper red ashing LED

Powering Docking Station: LED appears as red ashing

Downloading data and DMS

1. To communicate with DMS and the Edge, turn on the Edge and plug in the USB cable from the edge to

the PC. Then, open TSI Quest Detection Management software DMS.

2. Click on the button. The instrument communications panel will appear. Select the Edge

instrument and model from the dosimetry family.

3. Click on the Edge(s) check boxes in the EdgeDock-5 section and then select the button.

+ DMS will state Download completed. Select the Data Finder tab to view your data

(if not automatically selected.)

4. See user manual for more details.

Locking/unlocking

1. Turn the dosimeter on and press the button to start measuring.

2. To enable the lock, press button. Then press three consecutive times, within one

second intervals.

3. To unlock, press the button within one second intervals and then press button.

Common noise dosimeter terms

Criterion Level (CL) - expressed in decibels (dB),

it is the maximum allowable accumulated noise

level that results in 100% dose. Regional noise

standards specify criterion level.

Dose - expressed in percent, it is the percent of

the maximum exposure that has accumulated

over the run time. 100% is the maximum

allowable exposure. 100% dose occurs for an

average sound level equal to the criterion level for

an 8 hour period.

Exchange Rate (Doubling Rate) (ER)- the

decibel level that would double or halve the sound

exposure. For instance with a 3 dB exchange

rate the sound exposure doubles with every 3 dB

increase, and the sound exposure is halved every

3 dB decrease. Regional noise standards specify

the exchange rate.

Lavg - stands for “level average” and is the average

sound level measured over the run time.

Leq - stands for “level equivalent” and is the

average sound level measured over the run time

but is calculated with a 3 dB exchange rate with

no threshold.

Max Level - the highest weighted sound level

that occurred, also allowing for the response time

that the meter is set to. If the meter is set for A

weighting with Slow response then the Max level

is the highest A weighted sound that occurred

applying the Slow response time.

Peak level - the highest instantaneous sound

level that the microphone detects. Unlike the Max

Level, the peak is detected independently of the

slow or fast response time the unit is set for.

Response Time (Fast, Slow, Impulse) - how

quickly the circuitry responds to changing noise

levels. These are ANSI/IEC dened response times.

Most occupational noise standards require slow

response time.

Threshold Level (Cut O) - noise levels below

the threshold are integrated as zero decibels. This

will aect Lavg, Leq, TWA, and Dose values. Most

regional noise standards specify the threshold

level, if any.

TWA (Time Weighted Average) - takes the

noise exposure accumulated in the run time and

applies an eight hour time period. If the meter was

in run for 5 minutes, the TWA takes that 5 minutes

of noise input and averages it into an 8 hour run

time. The TWA in this case would be much lower

than the Lavg.

Weighting (A,C,Z) - frequency lters that

cover the frequency range of human hearing.

A weighting greatly attenuates high and low

frequency noise to mimic how the human ear

hears noise. C weighting also attenuates high

and low frequency noises, but not nearly as much

as A weighing. Z weighting does not apply any

attenuation, or weighting, to any frequency.

Most regional noise standards require a weighted

measurements.
