*) These are the standard wire colors. Other colors may be applied. In that case
the loadcell has to be checked by measuring the resistances per wire group:
Exc + en - (420 Ω), Sense + and - (420 Ω) , Signal + and - (350 Ω).

Codes CR and LF
a = either a blank, or a minus sign
x = blanks and/or weight figures
b = decimal dot *)
c = blank
k and g = weight unit: kilo gram
*) In weight figures with 2 or 1 figure behind the decimal
the decimal dot is in position 6 or 7.
Weight figures without a decimal are transmitted without a
decimal dot too.
G = Gross weight
N = Net weight
T = Tare weight
QTY = Quantity of counted pieces
PCS = Weight of one single piece. The position of the
decimal dot is here dependent on the
presentation of the figure itself.
g = weight unit: gram
