With the Checkweighing application, you
can check whether the sample on the
weighing platform matches a target
value, or lies within a given tolerance
range. Checkweighing also makes it easy
to fill sample materials to specified target
weight.
Features
– Enter the nominal or target weight
(setpoint) and the tolerance range delim-
iters either using the keypad or
by saving the weight value from
a load on the platform.
– Enter the tolerance limits as absolute val-
ues (Min and Max) or as percentages of
the target. Configuration:
Appl O: 4.5.
– The target value can be taken over
as a weighed value from a weighing plat-
form, and the tolerance limits are defined
by the percentage of deviation from the
target value (menu code 4.5.2). The fol-
lowing percentages can be selected as the
deviation: 0.1%, 0.2%, 0.5%, 1%, 1.5%,
2%, 3%, 5% or 10%.
– The target value, lower tolerance limit
(minimum) and upper tolerance limit
(maximum) can be taken over as weighed
values from the weighing
platform.
– Target and tolerance limits checked dur-
ing input; values must conform to: Upper
limit > Target > Lower limit >
1 digit.
– Checkweighing range: either 30%
to 170% of the target, or from 10%
to infinity.
– Results are shown on the main display
and the bar graph and sent to control
output ports for further processing.
– Toggle the main display between weight
and tolerances limits by pressing w. If
the weight on the readout is outside the
tolerance range, “
LL" (too low) or “HH"
(too high) is displayed.
– Activate info mode by pressing I
– Automatic printout of results.
Configuration:
Appl O: 4.6.
– Automatic taring of container weight.
Configuration:
Appl O: 3.7.
– Automatic initialization with the
most recently saved application data
when you switch on the Midrics.
Configuration:
Appl O: 3.8.
– Closing application program;
deleting parameters:
The value for reference sample weight
remains active in the reference memory
until you delete it by pressing the
c key, overwrite it or until you select a
different application.
– Restore factory default settings.
Configuration:
Appl O: 9.1.
Checkweighing entails comparing
the current weight value to a defined tar-
get. You can enter the value for this tar-
get using the keypad, or by saving the
weight value displayed.
You can also define upper and lower tol-
erance limits based on this target. You
can do this by:
– Entering absolute values using the
keypad or placing the desired amount of
weight on the platform and saving the
value, or
– Entering each value as a percentage
of the target weight
The initial application values are valid
until deleted by pressing the c key or
until overwritten by new values. They
also remain saved after you switch off
the scale.
– Tare function:
1) If you store a tare (weight value)
by pressing the ) key, you can later
enter a tare value manually. The tare
value you enter is added to the stored
tare value.
Setting: menu code 3.25.1
(factory default)
2) A tare value entered manually
overwrites a stored tare value (weight
value). If you enter a tare value manually,
a tare value (weights value) stored later
overwrites the manually entered value.
Setting: menu code 3.25.2
Operating menu setting:
Appl O: 3.25.
