26.  ATTACHING THE MOUNTING FIXTURES   
The mounting fixtures provided with the AD-4212A/B series balance are used to secure the weighing 
unit from above in a determined position, when the weighing unit is built into a system. To attach the 
fixtures to the weighing unit, use the screw holes after the three leveling feet are removed from the 
bottom of the AD-4212A/B series balance weighing unit. 
 
Attachment Procedure
 
1.  Remove the weighing pan, pan support and dust 
guard. Then, remove the three leveling feet. 
Caution 
Removing any other screws from the bottom of 
the weighing unit could damage the weighing 
sensor. 
 
2.  Use the leveling feet screw holes to attach 
the mounting fixtures to the weighing unit. 
Using the screws and washers provided with 
the mounting fixtures, secure the attaching 
fixtures to the weighing unit, two screws in 
the front and one screw in the back. 
Notes 
When attaching a mounting fixture, press 
the tabs against the weighing unit casing 
(one fixture in the front and another in the 
back) and determine the fixture position. 
When the weighing unit is placed upside 
down to attach the mounting fixtures, use 
much care not to press on the pan boss 
directly. Applying excessive force to the 
pan boss may damage the weighing 
sensor. 
 
3.  Secure the weighing unit from above.   
Notes 
The screws to secure the weighing unit to the 
weighing platform are not provided. Prepare 
appropriate screws with a size corresponding 
to the M6 screw.   
The screw hole diameter: 6.5 mm  
When the leveling adjustment is difficult to 
perform due to the installation conditions, 
place a shim between the fixture and the 
securing surface, or use two nuts. If the 
adjustment is still difficult to perform, perform 
calibration before use. Then, the balance will 
function normally.
