INTRODUCTION
SKC NoiseCHEK Personal Noise Dosimeter Cat. No. 701-001NBS (Figure 1) measures a worker’s daily
noise exposure in the workplace as required to meet regulations and standards for compliance and is
intrinsically safe.
NoiseCHEK has a ½-inch Class 2 microphone and is worn on the apex of the shoulder with the
microphone close to the ear and away from the neck. Clothing clips on each end of the device attach the
dosimeter securely to a worker’s shoulder.
Program up to four virtual dosimeters in the noise dosimeter for simultaneous compliance and monitoring
per OSHA, ACGIH, MSHA, and a User Custom option to meet internal standards that may exceed the
exposure requirements of regulations. Settings are modified/enabled using SKC DataTrac®dB Software
for NoiseCHEK. See Using DataTrac dB Software.
A note about default settings: NoiseCHEK has been shipped with programmed settings for OSHA
compliance and AIHA recommendations listed in the table below.

GETTING STARTED
xDo not apply stickers to the back of the dosimeter because this can cause connectivity issues
while the dosimeter is in the charging dock.
Charging the Battery
Set up the charging train (Figure 2a or 2b as applicable) and completely charge the battery before
operating the dosimeter. See Determining Battery Charge Status. Note: Cat. Nos. 701-001K3NBS,
701-001K3NBS-C, 701-001K5NBS, and 701-001K5NBS-C feature a carry case with charging cable
installed to charge dosimeters inside the case. See Charging Train in Carry Case with Charging Cable
Installed and Figure 2b.
1. Prepare the charging dock (1-unit Charging Dock Cat. No. 701-002 or 5-unit Charging Dock Cat.
No. 701-003).
a. Insert the power supply into the power jack on the back of the charging dock.
b. Plug power supply cube into 100-240 V power supply. The power LED on the back of the
dock will light up blue when connected to the power supply. Note: You can also charge
NoiseCHEK by connecting the charging dock to your PC or a USB battery bank with a
USB cable. Charging time may increase significantly depending on the power available
from the USB port used.
2. Place the NoiseCHEK in the prepared charging dock. Battery charging status
bars will be displayed on the dosimeter screen (see right); five amber LEDs will
blink during charging. Full charge is indicated by five green blinking LEDs.
Note: When the battery is fully charged, the LCD (display) will shut down. The
green LEDs will continue blinking while the noise dosimeter remains in the
charging dock.

Notes and Cautions
xSubstitution of components may impair intrinsic safety. AVERTISSEMENT: La substitution de
composants peut compromettre la Sécurité Intrinsèque.
xTo prevent ignition of hazardous atmosphere, batteries must only be charged in an area known to
be nonhazardous. AVERTISSEMENT: Afin de prévenir l'inflammation d'atmosphères
dangereuses, ne charge les batteries que dans des emplacements désignés non dangereux.
xUse only SKC charging dock Cat. No. 701-002 or 701-003.
xMaximum charge input voltage Um = 6.71 V.
xThe battery used in this device may present a risk of fire or explosion when heated above 212 F
(100 C) or incinerated. Battery can be replaced only by SKC authorized service center.
xWhen transporting dosimeters, ensure that they are placed in their designated areas inside the
case, not on the charging dock.
xDo not apply stickers to the back of the dosimeter because this can cause connectivity issues
while the dosimeter is in the charging dock.

Changing Time/Date
Use DataTrac dB Software to adjust the time/date. Upload the setting from the PC to the dosimeter(s).
See DataTrac dB Software for NoiseCHEK User Manual.
Recording/Playing a Voice Note
Record a voice note to identify details like the kind of noise being sampled, location of sampling, wearer’s
job description, and other relevant items. You can upload and play a voice note on a PC using DataTrac
dB Software. Only one voice note can be held in NoiseCHEK, and it must be deleted or uploaded to a PC
before another note can be recorded.
Note: Disable Voice Note using DataTrac dB software. See DataTrac dB Software for NoiseCHEK User
Manual.
1. From the Home screen, press and hold the Voice button to begin recording a note.
Note: Maximum recording time is approximately 44 seconds.
2. End recording by pressing the Voice button again (otherwise it will be ended
automatically when recording time exceeds maximum limit). See below.
a. To save the recording, select Home (press green button). The white LED
will continue to flash intermittently (when dosimeter is powered on but not
running) to indicate that a recording is present. If you try to record another
note in the meantime, you will see the message that a recording is present.
See Voice Note Status.
b. To delete the recording, select Delete (press red button). Select Yes (press green
button) to confirm; the message that the recording has been deleted will appear. The
white LED will stop flashing. See Voice Note Status.

Voice Note Status
Attaching NoiseCHEK on a Worker
Attach the NoiseCHEK to the worker’s shoulder after the unit has been turned on and calibrated and
before the sample run is started.
1. Choose the shoulder facing the highest level or source of noise. Place
the unit on the top of that shoulder with the microphone as high as
possible so it can collect maximum sound. Turn the wearer’s head
toward the dosimeter to make sure the chin does not touch the
dosimeter.
2. Fasten the clothing clips securely to the shirt. See right.
3. During sampling, keep clothing from touching the windscreen to avoid
contaminating results.
Removing/Reinstalling Windscreen
Remove windscreen: Hold the windscreen
collar (with arrow on collar facing you), turn it to
the unlock indicator on the dosimeter. Lift the
windscreen from the microphone.
Reinstall windscreen: Seat the windscreen over the
microphone (with arrow on collar facing you), turn it to
the lock indicator on the dosimeter to secure it. Note:
You should feel/hear a click as it is locked in place.

Using DataTrac dB Software
NoiseCHEK communicates with a PC via SKC Charging Dock Cat. No. 701-002 or 701-003 and DataTrac
dB Software. With DataTrac dB software, you can:
xProgram and modify presets in your dosimeter setup including virtual dosimeters, octave band
display, auto lock, and more (Figure 4).
xSchedule sample runs.
xUpload data for viewing and/or generating and sharing summary and compliance reports.
Figure 4. DataTrac dB Setup
When all four virtual dosimeters and octave band data logging are enabled and log
data is set to 1 second, it will take approximately 3 hours (1/3 octave) or 1 hour
(1 octave) to download data accumulated during an 8-hour run. Select log octave
band data and 1 second log interval only if you need and intend to use this kind of
data.

skcinc.com Form 37186 Rev 220106 Page 16
Install DataTrac dB Software
The NoiseCHEK noise dosimeter communicates with a PC via USB cable and charging dock (1-unit or 5-
unit) and DataTrac dB Software (Figure 5). Connect up to five NoiseCHEK dosimeters in the 5-unit
charging dock to upload settings. Note:Do not apply stickers to the back of the dosimeter because this
can cause connectivity issues while the dosimeter is in the charging dock.
1. Connect charging dock to PC using included USB cable.
2. Download from https://www.skcinc.com/catalog/datatrac/DataTracdB/setup.exe or
copy from USB drive “setup.exe” and install DataTrac dB as instructed. DataTrac
dB will launch automatically.
The DataTrac dB Installer requires administrator privileges
to install properly.
3. Place noise dosimeter(s) in the charging dock to complete
the communication train (Figure 5). Note: DataTrac dB will only
detect dosimeters that are properly seated in the connected
charging dock.
To program and upload settings to your noise dosimeters and download run data to your PC, see
