Notes:
•Address indicator could set is from 1~26, while
communication address is corresponding from A~Z;
•Instruction from A~Z is transferred in ASCII code;
but the example listed in table is in Hex. code. When
communicating with PC via the hyper terminal software(This
software is with windows operating system),you should
choose “transmit in hex format”, or else you must convert
the example to ASCII code;
•Instruction Q,R,S,T U is read/write operation for
data memory. There are many strings in data memory, but
one instruction from pc only triggers one operation, hence
several instructions should be sent from pc one by one
to do these operations

When indicator is at zero,then current display will show 0;
when indicator is at the weight corresponding to 20mA, then
current display will show 20mA. (Refer to parameter setting
for how to set the weight corresponding to 20mA).

Press [Calib] key, indicator will display [CALIb],it indicates
that it’s at calibration status. Press [ENTER] key, then
calibrate step by step as followed table:

One cycle is from charge to discharge, times is from 0~99 while 0 means
times is limitless
12
From t0 to t7, value set is from 0.0~9.9 seconds; always leave these
parameter as default setting, they are time to control the total process
more precisely
13
When D of C parameter set as 0, parameter t3 and t4 are disabled

16
Ensure there is no load and stable indicator is on
5.1 Turning on
When indicator is powered on, it will display 0~9, then it comes
to weighing status. If the unloaded scale divates from zero
point but still within auto zero range, then indicator will
come to zero automatically;
Before Weighing
Make sure that:
a. The load cell signal cable is connected and properly
secured.
b. The scale is turned on.
5.2 Zero manually
If the unloaded scale divates from zero after auto zero when
turned on, but it’s still within manual zero range and the stable
indicator is on, press [ZERO] key, then indicator will come
to zero and zero indicator will be on;
5.3 Tare
At weighing status, when the current display is positive and
stable, press [TARE] key will tare off the current weight and
indicator will display 0, zero indicator is on
5.4 Date/time set
Press[SET] key, and then press [ENTER] key and set date, then
press [ENTER] key and set time.
5.5 Start/Stop
13
Press [START] key or short connect Pin 1 and Pin 2 as listed
above, indicator will enter into automatic control status;
press [STOP] key or short connect Pin 1 and Pin 3 as listed
above, indicator will exit automatic control status;
5.6 Manual work mode
When scale is ready for weighing, short connect Pin 1 and Pin
4 of control socket(Indicator I3 will be on),then short connect
Pin 1 and Pin 6 of control socket, (Indicator I5 will be on),then
it will start charge material. When the loaded material reaches
OK range, then short connect Pin 1 and Pin 5 of control
socket(Indicator I4 will be on),then short connect Pin 1 and
Pin 7 of control socket, (Indicator I6 will be on),then it will
start discharge material. This is one cycle in manual work mode.
5.7 Automatic work mode
When scale is ready for weighing, press [START] key or short
connect pin 1 and pin 2 of control socket to enter into automatic
control mode. Always short connect Pin 1 and Pin 6 of control
socket(Indicator I5 will be always on) if there is no required
for charge material, and indicator will begin charge
automatically. Always
short connect pin 1 and pin 7 of control socket(Indicator I6
will be always on)if there is no required for discharge material
only when O6 is on. Then after o6 is on, indicator will begin
discharge automatically. When indicator check that rest
material in the hooper is within zero range, it will begin the
next cycle automatically.
5.7 Input/Output hardware check
At inner code display status, user can check whether the
hardware of input/output connectors are good or not. When there
is input for I1, then O1 will be on; when there is input for
I2, then O2 will be on….when there is input for I6, then O1~O7
will be on. If O indicator is not on, then it’s not good.
6. OPERATION ERROR CODES
Err 1 Can’t meet requirement of tare
Err 2 Can’t meet requirement of zero
Err 3 Incorrect input for date/time
Err 4 EEPROM chip is damaged
Err P
