Automatic zero setting for negative readings
Procedure will succeed automatically if during several seconds the scale readings are negative or
the scale is under loaded. Other terms and conditions of automatic zero setting are the same as for
the zero setting with the use of the key.
Zero maintaining i.e. „zero tracking”
This feature prevents from "sliding" of the scale’s zero resulting from various external factors that
may affect the zero indication. It consists of an automatic zeroing when the platter is unloaded.
Other terms and conditions of zero tracking are the same as for the zero setting with the use of the
key.
4.4.
Taring
The scale features the tare subtracting function (subtracting the tare reduces the weighing range by the
tare value). Activity of this function is signalized by
indicator.
To activate the function press the
key. If the scale is stable or will achieve stability within
1 second the current platter load will be considered as the platter weight. In case of instability the taring
is not effected and the
W3:SCALE UNSTABILE
error is displayed.
The maximum tare value depends on the type of scale and is indicated in the Section 2.2.
Technical specifications of this manual.
Turning off the tare is effected after removing the load from the platter and pressing
the
key or automatically after removing weighted articles. In order to turn off the tare
automatically there should be effected the process of weighing articles which takes place when the
load of the platter is stable and greater then the
MINIMUM RESULT
set in the
USER MENU
.
Example of weighing with taring:
– the scale is set to zero, the
and
indicators are lit,
– load the scale (e.g. with a basket),
– the scale indicates 0.788 kg, press the
key
– the tare value is inputted, the scale indicates 0.000 kg and the
and
indicators are lit,
– remove the load (a basket),
– the scale indicates -0.788 kg, the
,
and
indicators are lit,
– put again the load on the platter ( its content),
– the scale indicates 0.506 kg, the result is stable, the
and
indicators are lit,
– read or transmit the result of weighing, press the
key,
– remove the load,
– tare will be switched off automatically,
– the scale indicates 0.000 kg, the
and
indicators are lit.
The scale enables setting the fixed tare value which is signalized by the lit
indicator.
Turn on the tare by pressing another time the
key while inputting the tare value or by single
pressing if the
FIXED TARE
setting in the
USER MENU
is active. It is possible to input several
tare values if the consecutive tare values are growing.
