WLREF adjustment file

From version 107 the WLREF parameters like certificate number, adjustment values and their uncertainties are handled automatically. All the parameters stated above must be entered into a text file with err extension.

The procedure shall look as follows:

1. WLREF sensors are calibrated yearly in the accredited lab that provides their certificates.

2. The information from the certificates is entered into the text files in the following format:

   1. First line contains the WLREF serial number.

   2. Second line conatins the certificate number.

   3. The following lines contain reference temperature, measurement error and its uncertainty for all the calibration temperatures. The values can be separated by tabs or by spaces.

   4. The file name is WLREF serial number.err.

An example of certificate and the e1203f21e1b5.err file contents is shown below:

e1203f21e1b5
246/2/25
-80,005	0,023	0,030
-55,003	0,011	0,030
-40,000	0,014	0,030
-20,003	0,020	0,030
-0,002	0,018	0,030
4,999	-0,006	0,030
9,999	-0,004	0,030
20,000	0,006	0,030
30,005	0,017	0,030
37,004	0,012	0,030
49,998	-0,003	0,030
105,005	0,013	0,030

The easiest method to create the err file adjustments part is to copy the contents of the table from certificate and then remove the Measured values column, enetring tabs between values ain a row.

1. The err files must be created for all the WLREF sensors that will be used.

2. The err files must be reviewed for correctness, officially released and stored together with the certificates.

3. The err files shall then be copied to the tablet into the Documents\Cal App\Adjustments.

1. If a user will Assign reference sensor to calibration row and for which there will be no err file, the Cal App will disable the calibration row.

In such a case, copy the correct err file into Documents\Cal App\Adjustments and click Info twice to refresh the main page. If the WLREF serial number will match the err file name, the row will be enabled.
