18.2. Print command “K1”
The “
K1
” command starts the continuous printing of instant data, that is, not averaged over
the logging interval.
You can set an automatic print interval using the
WAAx
command. (The index x defines the
interval, as reported below.)

To obtain a continuous printing you should send the two WAAx commands (with x=1, 2, 3,
etc.) and then K1.
Notes:
1. In RS485 mode, the WAAx command should not be used if multiple instruments are
connected on the same line.
2. The print interval index, set using WAAx, is not recorded in the permanent memory and the
instrument, after turn off and turn on, restarts with the index at 0, that is, ready for single
print.
3. Due to the response time limits (a query per second and maximum 5 records in 2 seconds),
you should dimension the number of instruments in the network according to the update
speed required by the application. For example, if an update every minute is enough, you
can connect up to 60 instruments in order to get a response in “real” time.
4. The measurements obtained using the K1 command are immediate measurements, not
averaged over the set interval, while the stored measurements are averaged according to
the logging interval.
5. The reading of the memory is performed using the KRxxxx yyyy command. You will get the
printing of pages from xxxx to yyyy inclusive.
The RM command gives the current logging page. The most recently complete page, already
available for printing, is the previous one. The system does not prevent the reading of the
current page: as the instrument memory is arranged in circular mode (endless loop), the
current page is partly formed by the last stored data and partly by the information stored
during a previous session that have not yet been overwritten.
