[email protected] 2.4 Exhaust Port & Fresh Air Inlet
There are two small ports on the left side of the charging port (see Figure 1). The Fresh air inlet port will
draw clean air in during an active test. The incoming air automatically counts as fresh air (O2, 20.9%vol).
The Exhaust port is the inverse of the Fresh air inlet port. During an active test, the used test gas will exit
the unit through the exhaust port. Optionally, tubing can be attached to the exhaust port using the included
twist connector to direct the used test gas to a suitable location.
2.5 Installation of Gas Cylinder
A gas cylinder which fits into the Docking Station must have the C10 fitting on it. Both 58L and
116L cylinders are suitable. Before installing the cylinder for testing the NXS, ensure that Calibration
concentration of gases are suitable for the NXS being tested.
To install a cylinder:
Remove thumbscrews and lift the handle up.
Install the cylinder to the gas regulator.
Fasten the cylinder straps and close the cylinder compartment.
Check the pressure gauge on the front panel.
After installing a gas cylinder, ensure USB is attached.
Re-install thumbscrews.
3. Testing
A Bump Test and a Calibration Test are the key features to ensure gas detectors are working properly
and the end users are safe. The NXS Docking Station provides bump testing, event management and
calibration from a simple to use multi unit station.
3.1 Calibration
Calibration is the comparison of measurement values delivered by a device under test with a calibration
standard of known concentration. It is very important to calibrate a device periodically for better
performance of the device and to assure sensor accuracy.
To perform a calibration:
Insert the monitor(s) into the bay facing down.
Slightly press down on the monitor until it locks into place.
Press the calibration button for 2 seconds to execute the Calibration test.
During the 90 second test period, bay LEDs begin to light as the test progresses.
When the test is finished, all (six) blue LEDs illuminate indicating the NXS has passed
the test (see Figure 3).
If only the third blue LED illuminates, the NXS has failed the test (see Figure 3).

Test Results
Insert the monitor(s) into the bay(s) facing down.
Press the Bump Test button for 2 seconds to initiate bump test.
Can perform up to 1,000 bump tests on a single charge.
Insert the monitor(s) into the bay(s) facing down.
Press the Calibration button for 2 seconds to initiate calibration
test.
All (six) blue Bay LEDs illumination indicates if the NXS has
passed the test.
If only the third blue Bay LED is illuminated, then the NXS has
failed the test.
Be sure the Docking Station is charged or plugged in before use.
(Note: A red power LED light indicates a low battery. To fully
charge the Docking Station, it should be plugged in for 3 hours.)
To turn on, press and hold the Calibration or Bump Test button
for 2 seconds.
The automatic power saver mode will turn off the unit after 5
minutes of inactivity.
To turn off, press and hold the Calibration and Bump Test button
for 2 seconds.

Troubleshooting
Bay Light does not turn on/test not performed
- Clean Monitor IR window
- IR interference (bright lights/sunlight)
- Monitor in gas alarm state
All tests fail
- Gas cylinder empty
- Gas Expired
- Wrong gas concentration(s)
Test results are not stored
- USB not attached or USB is full
If you’re unable to resolve technical issues, please contact the
product’s authorized reseller or the Nextteq service center.
Important Notes
USB drive must be installed to store the test results.
Be sure the latest NXS Firmware is installed in the Nextteq Docking Manager
Software. The NXS portable monitor firmware will then be updated during the
next calibration or bump test.
For bump testing, ensure the cylinder gas concentration is above the
“Low Alarm” setting of the NXS Single Gas Detector.
For calibration, ensure the NXS “Cal Concentration” setting is the same as
the cylinder gas concentration.
Any monitor that fails the bump test or calibration must be re-calibrated or
bump tested again. If the attempts fail continuously, please do not use the
detector and contact your authorized Nextteq International Distributor or
Nextteq International.
When changing NXS settings using the USB from the Docking Station or
when using IR Link in the Docking Station, remember to click the “write”
button to save customized settings.
