A. Each Model 2055 calibration kit includes a bottle of zero gas, a bottle of span gas, all required fittings, tubing, etc., and a UIP (User Interface Program) for use on an IBM compatible PC with DOS 3.3 or later. It will not run on Windows or a Macintosh computer with a DOS simulator package.
There are two methods of calibration for the 2001 and 1502 carbon dioxide sensors. The quick field calibration requires only the UIP program and a known carbon dioxide standard to calibrate to. This takes 3-4 minutes. A full zero point and span calibration requires the gas canisters in the Model 2055 kit and takes 6-8 minutes. All calibration is done through software, there are no potentiometers to adjust. One canister of gas may be used to calibrate up to ten sensors.
