MGT Docking Station version II
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 MGT, ensure that Calibration concentration of gases are as
same as MGT.
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 MGT
has passed the test (see Figure 3).
✓
Otherwise, the third blue Bay LED illumination indicates if the MGT has failed
the test (see Figure 3).
Bump test and calibration are the key features to ensure the safety of devices and
users. The MGT Docking Station version II provides bump testing, event
management and calibration from a simple to use multi-unit station.
