F----L
Lower zero position of sensor signal
F----H
Weighing capacity is exceeded
C----F
Calibration error, instability or not at zero point during calibrating
C----H
Calibration error, items on the pan or at higher zero point during calibrating
E-----
Storage calibration data error, re-calibration is necessary
------
Zero point of the scale disorder / mechanical defect of the scale

Interface RS 232C
An integrated RS-232-interface enables you to automatically send the weighing data to
PC.Relevant codes and control commands are specified as following.

Remote control instructions
Via the RS232 data interface, the computer can control the balance with subsequent commands.
If the transmit / device setting is 27 (27=1B
hex
, default setting), the remote control commands
are sent to the balance by ASCII code:
1BH+70H(ACSIICode p): sending data
(Print)
1BH+71H(ACSIICode q): calibration function is active (CAL - Key)
1BH+72H(ACSIICode r): Counting function is active
1BH+73H(ACSIICode s): Weighing unit selection
1BH+74H(ACSIICode t): Taring
(TARE - Key)
