Viewing Data as a Graph
The Graph Sections allows you to see the values after the computer has download the data from
the monitor. Data will automatically be graphed showing the CO2 levels in ppm or %, Temperature
in Fahrenheit or Celsius, and Relative Humidity in %. This data is shown in the Gas Concentration
Graph Section, Temperature Graph Section and Relative Humidity Graph Section respectively. You
can click on the Temperature Unit Switch to change between Fahrenheit and Celsius.
The Concentration Zoom In and Zoom Out button allows you to view the CO2 concentration in
four scales: 400 ppm, 1000 ppm, 2000 ppm, or 1%. The Temperature and Humidity Zoom In and
Zoom Out buttons let you switch the temperature and humidity graph scales as well.
The Time scale of all Graph Section is always 1 hour apart. The Time Move Forward and Backward
buttons allow moving the time forward or backward if the log time is longer than 6 hours.
Data Archive
This section of the screen includes two buttons: Save Data button and Open File button.

Calibration
The SAN-0001 comes pre-calibrated from the factory. However, the CO2 sensor should be
calibrated at least once a year, or as described in your company’s safety procedures. You can
perform the calibration yourself, or you can return it to CO2Meter for factory calibration at a
nominal fee.
CO2 can be zero and/or atmospherically calibrated. Zero calibration requires 100% nitrogen (0%
