11  Comparator Function
This function compares a display value with the upper limit (HI) and the lower limit (LO) and
displays these results.
It is necessary to set the “comparator function ( 
 f6 0 
 ~  
f6 7 
 )” parameters, upper limit
value (HI) and lower limit value (LO) in the function table, in advance to use this function.
It is necessary to install option OP-03 or OP-04, if you use the relay output of the
comparator.

Parameter List and Word Definition
The “ near-zero “ is within ±4 digits from the zero point in the unit of kg.
The “digit” is a unit of display, and is equivalent to the minimum graduation.
The “zero point” is the fundamental starting point to weighing.
 Function table
Meaning and Purpose
f6 0
The scale always compares the current display value. Pressing the
SET
 switch turns the comparator on and off
f6 1
The scale always compares the display value.
f6 2
The scale always compares the display  value if not near-zero. Press
ing the 
SET
 switch turns the comparator on and off
f6 3
The scale always compares the display value if not near-zero.
f6 4
When the display value becomes stable  the scale compares the
display value. Pressing the 
SET
 switch turns the comparator on and off.
f6 5
When the display value is stable the scale compares the display
value. It does not compare on an unstable condition.
f6 6
When the display value becomes stable, while not near-zero,  the scale
compares the display value. It does not compare on an unstable
condition. Pressing the 
SET
 switch turns the comparator on and off.
f6 7
When the display value becomes stable and not  near-zero, the scale
compares the value.
Caution
The upper limit value (HI) must be greater than the lower limit value (LO).
The parameters of the upper limit value (HI) and the final value (HI) use the same memory.
The parameters of the lower limit value (LO) and the zero band (LO) use the same memory.
The upper/lower comparator function, the simple batch function and the full/dribble batch
function cannot be used at the same time because these parameters use common memory.
