ST

 

Set the tare point - this command will activate the net weighing function, by storing the current weighing signal output 

value as a tare value. The ST command is rejected if the weighing signal is fluctuating, as defined by the 

“tare no-motion” 

function. The “tare signal stable” bit in the “info status” return must therefore be active before a ST command can be 
accepted. Issuing the ST command, which has no parameters, will return the 

OK

 or 

ERR

 response. If 

OK

 is returned, then 

t

he “tare active” bit in the response to the “info status” (IS) command will be activated.  

 

RT

  Reset the tare - this command cancels the net weighing mode, and restores the current zero. The weighing signal 

output returns to the gross mode. Issuing the RT command, which has no parameters, will return the 

OK

 or 

ERR

 response. 

If 

OK

 is 

returned, then the “tare active” bit in the response to the “info status” (IS) command will be activated.

 

 
 
 

3.3  OUTPUT COMMANDS 

– GG, GN, GT, GS, GW  

 
The following commands provide the means of obtaining an output results from the device. 

 
GG

  Get the gross value - returns the current gross weight value. Issuing the GG command, which has no parameters, will 

return the gross weight value in the format 

G+01.100

 . 

 
GN

  Get the net value - returns the current net weight value. Issuing the GN command, which has no parameters, will 

return the net weight value in the format 

N+01.100

 . 

 
GT

  Get the tare value - returns the current tare weight value. Issuing the GT command, which has no parameters, will 

return the tare weight value in the format 

T+01.100

 .

 

 
GS

  Get the A/D sample value 

– returns the current output result of the A/D converter 

(ADC). This facility is useful when developing the application, or when calibrating the 
system, as it allows a check to be made of the operating range of the ADC. Issuing the GS command, which has no 
parameters, will return the ADC output value in the format 

S+100000.
