9.  FUNCTION SWITCH AND INITIALIZATION 

9-1  Permit or Inhibit 

The  balance  stores  parameters  that  must  not  be  changed  unintentionally  (e.g.  Calibration  data  for 
accurate  weighing,  data  for  adapting  to  the  operating  environment,  control  data  for  the  RS-232C 
interface).  There  are  two  switches  for  protecting  the  parameters.  The  switches  can  select  either 
“permit”  or  “inhibit”.  The  “inhibit”  protects  parameters  against  unintentional  operations.  There  is  an 
additional switch for the extended functions of the AD-4212A. 

 

Switches 

 

 

 

 

 

 

 

 

Note: Only available for the AD-4212A series balance. 

For details, refer to “20. EXTENDED FUNCTIONS 

 

 

 

 

 

 

Operation 

1  Press the ON:OFF key to turn off the display. 

2  While pressing and holding the PRINT key and the SAMPLE key, press the ON:OFF key. The 

balance displays   

p5

    . 

3  Press the PRINT key. Then the balance displays the function switches. 

4  Set the switches using the following keys. 

SAMPLE key 

To select the switch to change the parameter. 

RE-ZERO key 

To change the parameter of the switch selected. 

 

0

: To inhibit changes.     

1

: To permit changes 

PRINT key 

To store the new parameter and return to the weighing mode.   

CAL key 

To cancel the operation and return to the weighing mode.
