G36 Oxygen Analyzer
Version 2.11 - March 2022 17
However, if you install an SD card in the analyzer, the internal memory will be saved on
the SD card every minute. If the analyzer alarm and logbook functions are on, the alarms
will also be logged on the SD card.
There are two log files in the SD card, a log file for O
2
values – g1x.log and a log file
for alarms – g1x.alm.
If you want to read the log files directly from the SD card using a Windows-operated
computer, you have to use Notepad. Do not open the log files in WordPad. WordPad will
damage the format of the log files, and the analyzer will be unable to log any more data
on the SD card.
The best way to read the log files is to copy them to the local disk of your computer and
then open them from your computer. This way, you can use any program that can open a
txt-file including Notepad, WordPad, MS Word and MS Excel.
The data in the log file – g1x.log includes five columns, i.e.:
YYYY-MM-DD
HH:MM:SS
Datalog of A-OUT 1

The SD card shall be replaced after two years due to the limited capacity.
Software and default configuration uploading
The folder bin at the SD card includes two files: G1.bin and g1parm.bin. G1.bin is the
software file and g1parm.bin is the default configuration file.
If Green Instruments delivers a new software version with two files named G1.bin and
g1parm.bin the following steps will guide you through the installation:
• Replace the old files at the SD card with the new files G1.bin and g1parm.bin that
you have received.
• Set the SD card back in the analyzer. Then, restart the analyzer. Now the analyzer will
automatically check the SD card to see if there is a new software version. If yes, the
new software will automatically be loaded to the internal memory of the analyzer.
• After uploading the new software version, reload our default settings by choosing
Load default settings in Tools setting\Service (password level 2)\Load default settings.
• After uploading the new software version, you have to reset the analyzer following the
instructions in chapter 7.
