4 Power on the gas analyzer
The LI-830 and LI-850 will turn on when power is supplied, so plug in the power
cable to turn it on. If you use an alternative power supply, it must be able to source
a minimum of 1.2 A at 12 VDC while the instrument warms up. After the war-
mup, the instrument will draw about 0.3 A at 12 VDC.
5 Connect with the gas analyzer
Start the software.
Click the Connection button in the upper right of the display. Select your instru-
ment from the list, set the data rate, then click Connect. Data will populate the win-
dow after connecting. You can enter the COM port manually by checking Manual
Port and setting the port number (COM#).
If you are using Windows
