A&D AD-4212A-100/200/600/1000, AD-4212A/B Comparator Function, Three-level comparison results

Page 44

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 HIOKLO 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.
