Advanced USB Data logging
** Caution: We have tested 100’s of USB flash drives and 99% of them work just fine.
Prior to data logging important data, make sure to test your USB thumb drive and
verify it is logging.
To install a USB flash drive, simply plug it into the right side of the display panel. This port will allow
the electronics to talk to your USB flash drive and save the stored data in an .csv file (excel compatible).
The data is stored in files by date and can be configured to save data at 1 minute intervals up to 120
minutes.
To select your data logging interval, simply go into the MENU screen and select SET DATA LOG-
GING. this will prompt you to a screen where you can set the value by minutes. Once selected, press
enter and your interval will be saved.
** For data logging purposes, it is important to correctly set the date and time so that the time stamp
will be saved along with the recorded oxygen value. To set the time and date, refer to section 3.3.

Analog Output 0 - 1V DC
** Caution: Analog output is internally powered and does not require external power.
DO NOT supply any voltage across these terminals as the output will be damaged. It
is also important to assure proper grounding of the external recording device.
The Analog output can be connected via the front display panel inside the analyzer door with the
connector marked “OUTPUT”. The connector takes an audio phono jack which is supplied with the
analyzer. The Center pin is your positive and outer pin is negative.
The analog 0 - 1 VDC output is scaled to the analyzer range. If a specific output is needed such as 0 -
1% or 0 - 25%, select MANUAL RANGE in the menu and select the appropriate output.
