A standard feature of all IRwin models is the logfile function. This is something that can be configured by the operator to be started at any time, or to be started automatically each time the instrument is turned on. The logfile will document the work in a structured way, including information like serial number, model, latest calibration, time and date, readings on screen, operation mode, GPS coordinates etc. Specific procedures offered by the instrument, such as Function tests (bump tests) for gas response and gas analysis using gas chromatography (GC), can also be saved. These reports will include data like serial number, time and date, pass or fail test results, GPS coordinates for the test etc.
The frequency of the logfile is of course something that can be configured according to local regulations and/or procedures. The large memory capacity of the unit will provide weeks of logged data even with the default value of one datapoint per second. This will give the user the flexibility and freedom to choose when to download the data.
One of the main reasons for providing a large memory capacity is the fact that access to a PC in the field may be limited. But large amounts of unsaved data logs would also create a risk of data loss.
