11.1. The formula to compare
Comparison is performed using the formula listed below and the results are displayed.
Five-level comparator mode
Results Comparison formula LED display
LOLO
Displayed value < LOLO limit value
(Or over in the negative value)
( Red LED on)
LO Displayed value < LO limit value
( Yellow LED on)
OK LO limit value ≤ Displayed value ≤ HI limit value
( Green LED on)
）
HI HI limit value < Displayed value
( Yellow LED on)
HIHI
HIHI limit value < Displayed value
(Or over in the positive value)
( Red LED on)
Three-level comparator mode
Results Comparison formula LED display
LO
Displayed value < LO limit value
(Or over in the negative value) ( Red LED on)
OK LO limit value ≤ Displayed value ≤ HI limit value
( Green LED on)
）
HI
HI limit value < Displayed value
(Or over in the positive value) ( Red LED on)
Seven-level comparator mode (portion weighing mode)
Results Comparison formula LED display
None
Displayed value < Level 1 lower limit value
(Or over in the negative value)
( No LEDs on)
LOLO
(Level 1) Displayed value < Level 2 lower limit value
( Red LED on)
LO
(Level 2) Displayed value < Level 3 lower limit value
( Yellow LED on)
OK
(Level 3)
Level 3 lower limit value ≤ Displayed value ≤ Level
3 upper limit value
( Green LED on)
）
HI
(Level 4) Level 3 upper limit value < Displayed value
( Yellow LED on)
HIHI
(Level 5) Level 4 upper limit value < Displayed value
( Red LED on)
None
Level 5 upper limit value < Displayed value
(Or over in the positive value)
( No LEDs on)
 The comparator values are common to the weighing and counting mode.
 Ignore the decimal point when setting the comparator values.
 The comparator values are maintained even if the power is turned OFF.
 Judgment order of comparison is from the top row to the bottom in the comparator
mode tables
 The entered comparator values are not judged. Even if the upper limit value is less
than the lower limit value, no error will be display.
