NOTE
Arbitrary values between 0 and 255 can occur in the binary output. Therefore the
ASCII codes for carriage return (0x0D), line feed (0x0A) and "NUL" (0x0), which are
frequently used for end detection, can also be contained. The receiving software must
therefore be set up for the fixed byte number of the answer and may not search
through the answer bytes for end characters.
Meaning of the status byte
In some output formats a status byte follows on the measured value. It is used according to
unit status for outputting different information. The highest bit (MSB) serves for differentia-
tion. In the case of errors (ErrXX in the display) MSB = 0 and the value of the bytes (0...99) is
equal to the error number XX. In undisturbed operation MSB = 1, the other bits are status
bits which then describe the scale status.

Bit 0..6 Meaning
Status messages
0 1 = Gross value outside display limits
1 0 = Gross
1 = Net
2 1 = Scaling too sensitive
3 1 = Standstill
4 1 = Limit1 active
5 1 = Limit2active
6 In two−range / two−division scale:
0 = Scale is in range 1
1 = Scale is in range 2
In counting scale:
0 = Weight display
1 = Count display
