If asking for last calibration data and the controller was never
calibrated, it answers with “0”; e.g. “
01<STX>0<ETX>
”.
If the controller was calibrated, it answers with “1” followed
by the calibration data. The
Data
field of the answer has
the following format:

The items in the
Data
field are separated by blanks.
If an item is not available (e.g.
Buf 3
if only a two points cali-
bration was performed) it is replaced by the “N” character.
Note
The “r485” message can appear on the LCD while the
controller is receiving or answering commands.
SETTING THE BAUD RATE
The transmission speed (baud rate) of the meter and external
device must be the same.
The meter is factory set to 9600 bps. To change this value,
use setup item 71.
