
READING WEIGHT, SETPOINT AND PEAK (IF PRESENT) FROM PC
The PC transmits
the ASCII string:
$aajckckCR
where:
j
= a ............. to read setpoint 1
j
= b ............. to read setpoint 2
j
= c ............. to read setpoint 3
j
= t .............. to read gross weight
j
= n ............. to read net weight
j
= p ........ to read the gross weight peak if the  parameter is set as  ; if,
instead, the  parameter is set on  the gross weight will be
read. To read the points, set the

parameter equal to 50000
Possible instrument responses:
-
correct reception:
&aaxxxxxxj\ckckCR
-
incorrect reception:
&&aa?\ckckCR
-
In case of peak not configured:
&aa#CR
where:
xxxxxx
...... 6 characters of the required weight value
Notes : in case of negative weight, the first character from the left of the weight characters takes on
the value “-” (minus sign - ASCII 45). In case of weight value is under -99999, the minus sign “-” is
sent alternated with the most significant figure.
Error messages :
in case of an instrument alarm for exceeding 110% of the full scale or 9 divisions above the value of
the parameter

, the instrument sends the string:
&aassO-Lst\ckck
in case of faulty connection of the load cells or of another alarm, the instrument sends:
&aassO-Fst\ckck
where:
s
................... 1 separator character (32 ASCII – space)
Generally refer to the SERIAL PROTOCOLS ALARMS section.

SEMI-AUTOMATIC ZERO (WEIGHT ZERO-SETTING FOR SMALL VARIATIONS)
The PC transmits
the ASCII string:
$aaZEROckckCR
Possible instrument responses:
-
correct reception:
&&aa!\ckckCR
-
incorrect reception:
&&aa?\ckckCR
-
the current weight is over the maximum resettable value:
&aa#CR
