Operation
Checkweighing
H
With this 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 a specified target weight.
Selection and settings in the
Applic. / Applic.2/ CHECK.WG
menu.
Features
– Enter the nominal or target weight (set point) and the tolerance range
delimiters either using the keypad or by saving the weight value of a load on
the platform.
– Enter the tolerance limits as absolute values (Min and Max), as a percentage
deviation from the target or as a relative deviation from the target.
Setting:
Applic./Applic.2/CHECK.WG/CHECK.RG
menu item 4.5.
– The target value can be taken over as a weighed value from a weighing
platform, and the upper and lower tolerance limits are defined as a percentage
deviation from the target value (setting 4.5.2). The following percentages can
be selected as the deviation: 0.1%, 0.2%, 0.5%, 1%, 1.5%, 2%, 3%, 5% or 10%,
selection using the
r
key.
– The target value, lower tolerance limit (minimum) and upper tolerance limit
(maximum) can applied as weighed values from the weighing platform
(menu item 4.5.1).
– The target value can be applied as weighed values and via asymmetrical percent
limits (menu item 4.5.3).
– The target value can be applied as weighed values and via relative weight limits
(menu item 4.5.4).
– Target value and tolerance limits checked during 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, as a bar graph and LED as well as sent
to control output ports for further processing.
