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.
