8. AUTO-TARE FUNCTION
The FS-D has an auto-tare function to be used with the comparator function enabled.
If the weight value is within the OK range and stable for a preset time, then the
indicator will automatically tare the weight and show zero. The Function “f22”
designates the timing to tare automatically. See “9. ADDITIONAL INFORMATION”
about the added F-Function settings related to the auto-tare function.
‰ To use the auto-tare function, set the function settings below.
f08-1: Compare all weighing data (other settings may be used depending on
the application).
f21-1: Auto-tare function enabled.
f22-0 ~ 9: 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 and so on.
‰ Take-away check weighing:
Take-away check weighing (negative comparison) is the way to compare the
negative weight taking away material from a container. Set the Function “f24-1”
together with the auto-tare function enabled “f21-1”. In this operation mode, the
indicator operates as “take-away the material” Æ “OK and stable” Æ “auto-tare” Æ
“take-away the material” Æ ······.
In this setting, the polarity of the target weight and the upper / lower limit weight are
ignored and the indicator shows the comparator results as below.
Note To start the take-away check weighing, be sure to use the
TARE key to tare
the weight of the container filled with material. The ZERO key may zero the
display, and the indicator goes below the zero point by taking out the material.
Then, the auto-tare function does not work.
‰ When the Function “f23-1 Tares the initial (container) weight.” is set:
To start the auto-tare function application, usually the container (filled with material) will
be placed on the weighing pan and its weight must be tared using the
TARE key.
When the Function “f23-1” is set, the indicator will tare the initial (container) weight
automatically.
Remove all load on the weighing pan to return to the zero point, the tare weight will be
automatically cleared. If the indicator could not return to the zero point because of a
zero shift, press the
ZERO key to clear the tare weight.
‰ If the indicator is equipped with the optional RS-232C interface, the OK weighing data
only can be sent out automatically. Set the Function setting “f06-7 Auto-print mode
+/- data”
