Power / Charging Connections
The OMD-480 is powered by a rechargeable ni-cad battery. The portable analyzer accepts a 12V DC wall
charge power supply with a 0.5A current rating. Southland Sensing supplies a universal 100 - 240V AC wall
charger that has optional plugs for almost all countries.
One of the unique features about the OMD-480 is its ability to be charging while it is functioning. This al-
lows the user to plug in the OMD-480 and use it continously 24/7 while measuring oxygen or data logging
via the USB flash drive.
In the left corner of the display is a battery icon. This shows the user how much battery life is remaining.
The icon will show three bars and be in green when it is fully charged. Two bars and yellow means it is at the
middle of its charge capacity and one bar and a red color and the unit should be recharged. While charging
the icon will have a AC Plug through the unit showing that the battery is indeed being charged.

Gas Connections
The OMD-480 with its standard H3 flow through housing is designed for positive pressure samples and
requires incoming sample lines. The sample connections are 1/8” Swagelok tube fittings. The user is respon-
sible for added sample system components as well as sourcing a calibration gas.
There is no recommended flow direction, the either bulkhead can be used as the inlet / outlet.
It is recommended to use Stainless Steel Tubing or a low permeable plastic tubing.
• Flow rate should be between 0.5 -
5.0
SCFH
• Inlet pressure should be between 5 -
5
0 PSIG
• Analyzer should be vented to atmosphere, take precau-
tion to make sure vent does not get blocked
