Congratulations
… and thank you for choosing SMART, a weighing indicator specially suited for
weighing applications.
Apart from its unique toughness and extraordinary small size, SMART comes
packed with features that will help you in industrial weighing applications.
Like other indicators from ESIT, SMART is produced to meet highest quality
standards.
This guide introduces you to SMART and shows how to get the most out of it.
Please note that some of the functions described in this user’s guide are
depending on orders.

(6) LOAD THE PLATFORM WITH THE REFERENCE WEIGHT. THE
REFERENCE WEIGHT SHOULD BETTER BE AT LEAST HALF OF THE
LOAD CELL CAPACITY.

with key; blinking digit can be changed
with key.
(9) To store the load calibration value and
finish calibration, press key. Indicator
resets itself and restarts with new
calibration value.
ATTENTION: CALIBRATION VALUES CANNOT BE CHANGED UNLESS THE
CALIBRATION PLUG, PLACED BETWEEN AND KEYS, IS REMOVED

Notes for MOD3 communication:
The transmission of weight value is performed when the indicator
realizes the code from the other side. By this way more than one indicator can
be connected to the same communication line. The data format is the same as
COMM 1.
For a PC to communicate with more than one indicator, this parameter
should be COMM3, and the communication hardware should be RS-485.
SCALE IDENTITY NUMBER SETTING
ONLY AVAILABLE IN COMMUNICATION MODE3
(1) Press the navigation key until the
‘communication’ menu appears
(2) Press to enter the ‘communication’ menu
(3) Press the navigation key until the
‘scale number’ menu appears
(4) Press to enter the ‘communication’ menu
(5) Last stored scale number value appears
with leftmost digit blinking

COMMUNICATION BIT SETTING
This parameter gives the number of bits in a communication byte. With 7 bits
communication 128 different characters can be coded. On the other hand 256
different characters can be coded with 8 bits communication.
(1) Press the navigation key until the
‘communication’ menu appears
(2) Press to enter the ‘communication’ menu

DECIMAL POINT COMMUNICATION SETTING
Communication with decimal point is available only in 8 bits communication.
Decimal point is sent in the most significant digit of the transmitted byte.
(1) Press the navigation key until the
‘communication’ menu appears
(2) Press to enter the ‘communication’ menu
(3) Press the navigation key until the
‘communication decimal point’ menu appears
(4) Press to enter the ‘communication decimal point’ menu

Example data stream for mod1 in 8 bits and decimal point included communication:
Display
+1234 ‘+’ ‘1’ ‘2’ ‘3’ ‘4’ CR
Hex 2B 31 32 33 34 0D
+123.4 ‘+’ ‘1’ ‘2’ ‘3.’ ‘4’ CR
Hex 2B 31 32 B3 34 0D
-12.34 ‘-’ ‘1’ ‘2.’ ‘3’ ‘4’ CR
Hex 2D 31 B2 33 34 0D
If there is a decimal point on the display, then the corresponding digit is
sent with hex80 added to the ASCII value.
Character HEX Character HEX
0. B0 (30+80) 5. B5 (35+80)
1. B1 (31+80) 6. B6 (36+80)
2. B2 (32+80) 7. B7 (37+80)
3. B3 (33+80) 8. B8 (38+80)
4. B4 (34+80) 9. B9 (39+80)
Example data stream for mod3 (addressed communication):
If address (scale identity number) is set as 65 (41h), the indicator will send the
weight data after receiving
(Wake-up) Address
HEX FFh 41h
If the address is set to 0then the indicator will send the weight data after
receiving any character from the serial receive line. The address may take any
value from 0to 255.
When more than one SMART indicator is connected to the same transmission
line, then the devices should have RS 485 communication hardware and all should
have unique addresses.

TRANSMITTING WEIGHT VALUE FROM SERIAL LINE WITH KEY
If in the communication menu, the comm-3 was set the weight value can be
transmitted by pressing key from the serial line. In order to transmit the
data, no-movement state must be achieved.
RESETTING DISPLAY VALUE TO ZERO (ZEROISE) WITH KEY
To reset the weight value to zero, press key.
In order to perform this function, the indicator
should be in no-movement state appears as
After key is pressed, the value turns to
zero and center-of-zero symbol is lit.

ERROR CODES
During weight measurement in some cases the SMART indicator produces some
error codes. These codes and their probable reasons are as follows:
Error 01: Over range
More than MAX+ (9*e) of capacity
