10-10 Comparator Function
The balance outputs the results of the comparison in three or five levels.
AD-4212A series balance: 3-level output (standard) or 5-level output when OP-04 is installed.
AD-4212B series balance: 3-level or 5-level output, switched by “Comparator output setting
( Cp-t )” of the function table.
The comparison results are indicated by HI OK LO on the display and are contact-output from the I/O unit.
The following five comparison conditions are available by “Comparator mode (
Cp )” of the function
table Cp fnc .
 No comparison
 Comparison when the weight value is stable or overloaded, excluding “near zero”
 Comparison when the weight value is stable or overloaded, including “near zero”
 Continuous comparison, excluding “near zero”
 Continuous comparison, including “near zero”
Note
“Near zero” indicates the amount of ten digits (digit = the minimum displayable weighing value).
The comparison is performed using the upper limit value and lower limit value.
The function table
Cp fnc has one more item: “Buzzer ( bep )” to select whether or not to sound the
buzzer depending on the results.
