11. Comparator
The comparator function is a function to compare the measured load values and the load value set beforehand.
The comparison result displays in judgement display section, and is output by the optional contact output.
11-1. Comparison operation of comparator
In the comparator comparison operation of this unit, there are three patterns “Upper/lower limit comparison
mode”, “Weigh in mode”, and ”Weigh out mode”.
The selection of the comparator comparison operation is executed by the setting of function F-20.
Function No. Set value Contents
0 OFF
1 All data
2 All data during stable condition
3 Data exceeding ＋5D
4 Data exceeding ＋5D during stable condition
5 Data except from －5D to ＋5D
6
Data except from －5D to ＋5D only during stable
condition
Upper/lower limit
comparison mode
7 Weigh in mode
F-20
8 Weigh out mode
Default has selected “Data exceeding +5D during stable condition”.
11-2. Target of comparator comparison operation
The target of the comparator comparison operation is selected by the setting of function F-21.
The target of the comparator comparison operation can be selected from “Gross value” and “Net value”.
Default has selected “Gross weight”.
11-3. Upper/lower limit comparison mode
The upper/lower limit comparison mode is a mode by which the load values are compared with the high limit
setting value and the low limit setting value, and the comparison result is output as a signal of HI (overamount),
OK (positive amount), and LO (lack).
When the function F-20 is form 1 to 6, it becomes in effective.
11-3-1. Operating condition of upper/lower limit comparison mode
The relation between the comparison output and the upper/lower limit set value of the upper/lower limit
comparison mode is as follows.
Comparison output Operating condition
Comparison
judgement display
Contact output
terminal
HI(Over amount) Upper limit value＜Display value HI HI terminal
OK(Positive amount) Lower limit value≦Display value≦Upper limit value OK OK terminal
LO(Lack) Display value＜Lower limit value LO LO terminal
●The comparator of this unit executes the comparison operation synchronizing with the display.
● An over display becomes the HI output during the plus over(OL), and the LO output during the minus output during the minus over(－OL).
