9. AUTO-TARE
The SJ-WP 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 can not 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 comparion
 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" Æ "OK and stable" Æ "auto-tare" Æ "take-away the objects" Æ ···.
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, tap the switch to clear the tare weight.
