Depending on which buffers you wil 

be using in your application, click on the 

diamond next to the User defined buffer 
that needs to be changed.  

a.

 

User defined Buffer 1, is the buffer 
table for pH 4.01;  

b.

 

user defined Buffer 2, is the the 

buffer table for pH 6.87;  

c.

 

and user defined Buffer3, is the 
buffer table for pH 9.18.   
 
 

For this example we will choose to change the values within the User 

Deinfed Buffer 2, pH 6.87, because this is the most commonly choosen 
table to change values to reflect pH 7.0.
