HV/HW-C/CP Series
10. Comparator
The comparator function can select a mode from "Five
-
level comparator mode", "Three
-
level
comparator mode (Upper and lower limit mode)" and "Seven
-
level comparator mode (Ranking mode)".
Each comparator mode compares the weighing value against the preset threshold values and
outputs the results using LEDs (yellow, green and red).
When the optional comparator relay output (HVW
-
04C) is installed into the scale, the
comparison result can sound the buzzer synchronized to LEDs and output as relay signal.
Five-Level Comparator Mode :
This mode compares the weighing value with
four threshold values (limit values) and outputs
results in five levels of LOLO, LO, OK, HI and HIHI.
Three-Level Comparator Mode (Upper and lower limit mode) :
This mode compares the weighing value with two threshold values
(upper and lower limit) and outputs results in three levels of LO, OK
and HI.
Seven-Level Comparator Mode (Ranking Mode) :
This mode compares the weighing value with five threshold values and outputs results in seven ranks.
Out of range (Negative value),
Rank 1 (LOLO), Rank 2 (LO),
Rank 3 (OK),
Rank 4 (HI),
Rank 5 (HIHI),
Out of range (Positive value)
To use the comparator modes, item
and of the function table must be specified
and threshold values (limit values) of the comparator must be set in advance.
Select a comparator mode at item
of the function table.

:
Three-level comparator mode (upper and lower limit mode).
:
Seven-level comparator mode (ranking mode).
Select a comparator condition at item
of the function table.
:
No comparison (comparator function not used).
:
All data is compared regardless of stability of value.
:
Stable data is compared (when stability mark lights).
:
All data is compared regardless of stability of value except "
near zero
".
:
Stable data is compared except "
near zero
".
:
All positive data is compared except "
near zero
".
:
Stable positive data is compared except "
near zero
".
Note
"
near zero
" is within
±
4
digits (four times the minimum weighing value that can be weighed)
from zero point in the weighing "kg".
