3.3 Millivolt display

This function is mainly used to test weighing system,

four-corner position-error of force-transmitted equipment

and load cell’s linearity.

1. Test weighing system

(1) If the indicator display variational millivolt value

according to add weight, thus indicate load cells are

connected correctly and force-transmitted equipment is

operated normally.

(2) If the indicator display OFL (or –OFL), thus indicate

the weight is too heavy (or too light), then need unload (or

add) the weight. But if always display OFL (or –OFL) after

changing weight, maybe the following reason cause:

a. Please check force-transmitted equipment.

b. Please check the load cell’s connection.

c. Please check Load cells.

2. Test four-corner position-error of force-transmitted

equipment

Please load same weight on scale’s every corner and

record individual millivolt value. If the values are obviously

different, please adjust force-transmitted equipment.

3. Test load cell’s linearity

Please load several same weight values within the

weighing capacity and record relevant millivolt value after

zeroing every time; if the discrepancy is bigger among

millivolt values, thus indicate that the load cell’s linearity is

not good, need change new load cell or adjust

force-transmitted equipment.

Inquiry：Regulate coil start and quantities.

Response：

a) Every coil state in response message is corresponding

to every data in data area；1=ON；0=OFF。The LSB in

first byte is start address in inquiry. Other coils are in

seriation from lowest to highest in the byte till full of 8pcs,

next byte same seriation.

- 91 -

b) If they are not 8 multiples, the last byte is full of zero

from the remain to the highest，which byte sections

indicate all of byte quantities.

For example：Inquiry weighing indicator 01 to read 40- 43

coil (Coil 43- 40 related status：0- 0- 1- 0).

8.2.4 MODBUS communication error message

When weighing indicator check other error message

except parity code( CRC or LRC)，indicator will send

message to host computer, the highest in function code is 1，

which means function code from weighing indicator to host

computer is added 128 based on function code from host

computer(For example: read register command 03H will be

changed to 83H).

Error code:

02: error data -received address, which is not permitted by

weighing indicator.

03: error inquiry data, which is not permitted by indicator.

Error message format：

1）RTU communication mode：

Address Function code Error code CRC parity

1byte 1byte 1byte 2byte

2）ASCII communication mode：

For example, host computer read coil(0040) by code 03.

1） RTU communication mode：

Inquiry command：01 03 00 28 00 01 04 02

Error response：01 83 02 C0 F1

2） ASCII communication mode：

Inquiry command：3A 30 31 30 33 30 30 32 38 30 30 30

31 44 33 0D 0A

Error response：3A 30 31 38 33 30 32 37 41 0D 0A

From response message, the present error code is 02,

which means the present received data address is error, not

permit by weighing indicator.
