Instrument: OLO1 (id: 1)
Although this example is for a specific instrument, the syntax is common to all of them. instrument_id specifies the instrument. For putting data, there is a list of variable short names with their corresponding measurement value. All of the qualifiers (i.e. the fields following "?" and "") are order independent.
