110 Instrument number
All instruments that are installed in or near the plot are given an unique instrument number which must not change over time.
When instruments are replaced or added, new codes are applied.
E.g. the fifth instrument in plot 3426 will thus receive instrument number 5.
From data submission year 2011 onwards the plot number and the instrument number are submitted in two distinct fields.
Instrument numbers should be directly transferred from the old numbering before the year 2010.
If this is not be possible, please indicate this in the field 'Other observations' in the PLM form.
