GM8802C-E Compact Transmitter 

- 6 -                                                                                                                 

GM8802C-0E110102 

2 Installation   

2.1 Connection of Load Cell 

Please refer to the picture in 

2.1

 

to connect load 

cells to the 

GM8802C-E 

transmitter. When you chose 

the four-wired load cells, you must bridge the 

SN+

 with 

EX+ 

and bridge the 

SN- 

with 

EX-

Because the input signal of the sensor is a analog 

signal, it is more sensitive to electronic noise, so this 
signal transmission should adopt the shielding cable , 
and should separate its from other cables to lay , should 
not tie up it together . The signal cable should be far 
away from exchanging the power.
