Byte 0 corresponds to byte 7 in the output area; for weight error, see also the table in Chapter 5.5.1.

ADCERR

Error of analog conversion/ load cell circuit (OR function of the E1,E3,E7 bits)

>Max

Gross value is higher than Max (maximum capacity); the full scale deflection was
exceeded.

OVL

Scale overload; Gross > Max + overload, Error 2

BELOW0

Gross weight is negative (< 0-1/4 d)

CZERO

Center of zero; weight within

0 +/- 1/4 d

INZSR

The gross weight is within the zero setting range

STND

The scale is stable

DIM

The gross weight has exceeded the full scale deflection (0-1/4 d > weight value
> Max+overload), (OR function of bits

BELOW0, OVL

).

E7

The input signal is negative (inverse conversion), Error 7

E6

No sense voltage, or Sense voltage is low, Error 6

E3

The input signal is > 36mV (no end of conversion), Error 3

E1

Arithmetic error (overflow), Error 1

CmdError

Error during execution (

cmdError

); e.g. the 'taring' operation is not handled,

because the scale is not stable. The error is stored in

LastError

(register 4). The

bit is reset with the

ResetError

bit (register 2).

ActionActive

The operation is handled; handling is busy

PowerFail

Power failure; is always set after power on. The PowerFail bit is reset with the

ResetPWF

bit (register 2) 'Reset power failure'.

TestActive

The analog test is busy

TareActive

The instrument was tared.
