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 a speci-
fied target weight.
Features
– Enter the nominal or target weight
(setpoint) 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) or as percentages
of the target. Configured in Setup
under:
Application:
Checkwgh.: Chck. input
– Results are output to the main display,
the bar graph and three control LEDs,
as well as to control output ports for
further processing.
– Toggle the main display from the
weight value to the tolerance limits by
pressing the
LLHH soft key, and back
again by pressing the
Weigh. soft

Checkweighing entails comparing
the current weight value to a defined
target. You can enter the value for this
target using the keypad, or by saving
the weight value indicated. You can
also define upper and lower tolerance
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
– by 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 a new value.
They also remain saved after you turn
off the Combics.
