 will disable the auto tare off function 

 

-

Tr_on

 will enable the auto tare function and tare off the first 

weight that is placed on the scale 

c. Press

 to save and return to other functions   

 

2.4.11 High Resolution Verification Mode (F19) 

This function is intended 

to 

be used only by the manufacturer for 

initial 

verification purpose. 
 

2.4.12 Gravity Compensation Device 

 C.G. (F20) 

This 

function 

stores 

the 

gravity 

value 

of 

where 

the 

scale 

is 

manufactured. 

Scale was calibrated according to the value stored. 

a.  Refer to the 

2.4.1

 on how to enter 

F20

 

b.  Use 

MODE

 to shift to next digit and use 

ON/ZERO

 to increase the 

value 

c.  Press and hold 

MODE

 to save or 

TARE

 to quit 

-When  the  change  is  saved,  scale  will  enter  calibration 

automatically to reflect the change in gravity. Please refer to 

2.4.14

 for how to calibrate the scale 

 

2.4.13 Gravity Compensation Device 

 U.G.

 

(F21) 

This function stores the gravity value of where the scale will be used. 
The value stored in F.21 will be used to compare with the value in 
F.20 to compensate the difference in gravity value. 

a.  Refer to the 

2.4.1

 on how to enter 

F21 

b.  Use 

MODE

 to shift to next digit and use
