2. Set up and Operation
2.1 Power turn on/off
The SGT Docking Station version II operates using only 2 (two) buttons for calibration and
Bump Test.
To turn on the power, follow the below:
✓Press and hold either Calibration or Bump Test button for 2 seconds.
✓The Power LED turns on to orange and blinks during the warming up and after while
turns to green when it is ready. When the unit has a low battery, the LED turns to red.
To turn off the power, follow the below:
✓Press and hold both Calibration and Bump Test buttons simultaneously for 2 seconds.
2.2 Bay LEDs and meanings
Each Bay has six blue LEDs (see Figure 2) which indicates the process status. Each of them
will turn on by order from left to right while testing. After testing is finished, make sure all six
bays are turned on otherwise, 3rd bay LED will be shown if test is failed.
2.3 Charging battery
The unit`s Power LED turns to red when the battery is very low as shown above. However, it
comes with a DC adapter with 5plugs which can be used to charge the unit using a 110V
power supply. A full charge will take approximately 3 hours and will last for approximately
1000 bump tests.
Note: Refer to Figure 1 for charging location.
Note: If unit is inactive for 300 seconds, it will automatically off (save power mode)
The button/unit only works when the power LED turns to green
SGT Docking Station version II
Figure 2

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 a
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
Gas Cylinder which fits to Docking Station II must have the C10 fitting on it. The size of 58L
and 116L are both suitable in cylinder compartment. Before installing the cylinder for testing
SGT, ensure that Calibration concentration of gases are as same as SGT.
To install a cylinder, follow the below:
✓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.
✓Re-install thumbscrews.
✓After installing a gas cylinder, ensure USB is attached.
3. Testing
3.1 Calibration
Calibration is the comparison of measurement values delivered by a device under test with
those of a calibration standard of known accuracy. It is very important to calibrate a device
periodically for better performance of the device and sensor accuracy, especially, when it is
safety equipment.
To perform a calibration, follow the below:
✓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 Calibration test.
✓During the 90seconds, bay LEDs begin to light as the test progress.
✓When test is finished, all (six) blue Bay LEDs illumination indicates if the SGT has passed
the test (see Figure 3).
✓Otherwise, the third blue Bay LED illumination indicates if the SGT has failed the test (see
Figure 3).
Bump test and calibration are the key features to ensure the safety of devices and users. The
SGT Docking Station version II provides bump testing, event management and calibration from
a simple to use multi-unit station.

3.2 Bump Test
Bump test is the process which checks and verifies the performance of the monitors and
ensures that sensors are correctly responding to the target gas.
To perform a Bump Test, follow the below:
✓Insert the monitor(s) into the bay facing down.
✓Slightly press down on the monitor until it locks into place.
✓Press the Bump Test button for 2 seconds to execute Bump test.
✓During the 20~30seconds, bay LEDs begin to light as the test progress.
✓When test is finished, all (six) blue Bay LEDs illumination indicates if the SGT has passed
the test (see Figure 3).
✓Otherwise, the third blue Bay LED illumination indicates if the SGT has failed the test (see
Figure 3).
SGT has passed the
test (six LEDs)
SGT has failed the test
(only 3rd LED)
Note: Do not use the monitors that failed the calibration test.
4. Trouble Shooting
4.1 Bay Light does not turn on /test not performed
✓Clean Monitor IR window.
✓IR interference (bright lights/sunlight).
✓Monitor in gas alarm state.
4.2 All tests fail
✓Gas cylinder empty –check pressure gauge if it indicates at least 100psi/10bar.
✓Gas Expired –check gas expiration date located on the cylinder.
✓Wrong gas concentration(s) –gas cylinder and SGT concentrations not same.
✓Wrong gas type –check the gas type.
