8. Comparator
The scale has three-, five- and seven-level comparators.
Each comparator mode compares the weight value against the preset limit values and
outputs the results using LEDs (yellow/green/red).
Note: When the unit is "lb-oz" or "tl", this function cannot be used.
•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.
•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.
•Seven-level comparator mode
(portion weighing mode):
Uses six comparator values to
compare the weight value and
outputs results in seven levels
of outside the lowest limit, level 1 (LOLO), level 2 (LO), Level 3 (OK),
level 4 (HI), level 5 (HIHI) and outside the highest limit.

9. Auto-Tare
The SJ-WP/-BT series has an auto-tare function to be used with the comparator mode
enabled. If the weight values are in the OK range of comparator limits and stable for a
preset period of time, the scale will automatic 1 ally tare the weight and show zero.
In some countries or areas, the auto-tare function cannot be used on the Legal for
Trade models and the selection in the function settings , and
is not available.
To use the auto-tare function, set the function settings below.
: Compare all weighing data (other settings may be used depending on
the application).
: Auto-tare function enabled.
to : Select the timing to tare automatically to avoid the wrong tare operation,
for example; too early to tare, to take a longer time to go to the next
weighing.
Normal comparison
Start with display zero after tare operation. Place or take away objects until the
comparison result will show OK. When the stable indicator is ON for a the preset
period of time specified in the function setting , the scale will automatically
tare the weight, show zero and be ready for next weighing to repeat.
Negative comparison for take-away (example with )
Take-away check weighing (negative
comparison) is the way to compare
the negative weight while taking away
objects from a container.
Set the function together
with the auto-tare function enabled
. In this operation mode, the scale operates as "take-away the objects" 
"OK and stable" "auto-tare" "take-away the objects" ···.
In this setting, the polarity of LOLO, LO, HI, and HIHI limit values are ignored and
the scale shows the comparator results as below.
Note: To start the take-away check weighing, be sure to use the TARE switch to
tare the weight of the container filled with objects. The ZERO switch may
zero the display, and the scale goes below the zero point by taking out the
objects. Then, the auto-tare function does not work.
When the function " Tares the initial (container) weight" is selected:
To start the auto-tare function, usually the container (filled with objects) will be
placed on the weighing pan and its weight must be tared using the TARE switch.
When the function is selected, the scale will tare the initial (container)
weight automatically.
When all load on the weighing pan is removed, the scale will return to the zero point
and the tare weight will be automatically cleared. If the scale does not return to the
zero point, press the switch to clear the tare weight.
