Comparator; The Formula To Compare - A&D SW-150KL Instruction Manual

Five-level and three-level comparators are available.
The five-level comparator mode uses four comparator values to compare the weight
value and outputs results in five levels of LOLO, LO, OK, HI and HIHI.
The three-level comparator mode uses two comparator values (upper and lower limit
values) to compare the weight value and outputs results in three levels of LO, OK and HI.
The results are output using LEDs (yellow / green / red).
When the optional comparator relay output (OP-03) is installed, the results are output as
a relay signal.
To use the comparator modes, the function settings "
specified.
Using the function setting "
0: five-level comparator mode
1: three-level comparator mode
Using the function setting "
0: No comparison (comparator mode disabled).
1: To compare all data.
2: To compare all stable data.
3: To compare all data which are more than or equal to +5d, or less than
or equal to -5d.
4: To compare stable data which are more than or equal to +5d, or less
than or equal to -5d.
5: To compare all data which are more than or equal to +5d.
6: To compare stable data which are more than or equal to +5d.
d = minimum display in kg (Refer to "15.1. Specifications".)
Also in the counting mode, "d" is equal to the minimum display of kg mode.

10.1. The formula to compare

Comparison is performed using the formula listed below and the results are output.
Five-level comparator mode
Results
Displayed value < LOLO limit value
LOLO
(Or over in the negative value)
LO Displayed value < LO limit value
OK LO limit value ≤ Displayed value ≤ HI limit value
HI HI limit value < Displayed value
HIHI limit value < Displayed value
HIHI
(Or over in the positive value)
LOLO limit value = Secondary lower limit value
LO limit value = Lower limit value
HI limit value = Upper limit value
HIHI limit value = Secondary upper limit value
