9. CHECKWEIGHING
Checkweighing is a working mode using two thresholds (Min and Max)
to control sample weight (LO - sample mass too small, HI - sample mass
to large, OK - sample mass correct).
Such solution enables fast evaluation of sample mass There is no need for
constant control of the weighing result. LO, OK, HI states are presented on the
display in a graphic form.
LO, OK, HI states are signalled with colours or presented by means of control
of external equipment systems.

For description on how to enable checkweighing and its
signals, go to section 6.4.2 of this user manual.
9.1. LO Threshold
<LO threshold>
parameter specifies displayed value of the net weight above
which outputs for MIN, OK and MAX states are active.
Procedure:
Open
<Lo threshold>
parameter, enter
LO
threshold value and press
Enter
. Press
button to save changes to the mass converter
memory.
9.2. MIN/MAX Threshold
<MIN
threshold>
parameter
specifies
net
weight
threshold
in the checkweighing mode, to which the threshold between MIN and OK
is switched.
<MAX
threshold>
parameter
specifies
net
weight
threshold
in the checkweighing mode, to which the threshold between OK and MAX
is switched.
Visualisation of outputs is enabled when mass value is higher than the value
of
LO threshold
