Features
– 4 different sequences for measuring the
tare weights, initial sample weights and
the backweights (backweighing result):
– Individual weighing
– Consecutive individual
weighing
– Combined weighing
– Serial weighing
– Choice of weighing sequence by select-
ing this parameter in the Setup menu
or by pressing the
Wg.seq soft key
(if the “Weighing sequence key” option
is set)
– Perform up to 99 backweighing routines
on a single sample
– Differential weighing with or without
tare weighing (not necessary for meas-
uring coatings or lamination layers)
– Define the number of decimal
places displayed for calculated results
– Define whether autosaving weight val-
ues is dependent on the stability param-
eter
– Define whether the minimum load for
autosave is dependent on the display
– List function, with
Display page for lots:
Lists all lots (up to 100 max.) with
the number of samples in each lot and
the processing status (tare weight,
initial weight, backweighed residue
(“backweight”)
View, create, rename or delete lots gen-
erated
Enter or change a factor for calculation
of results
Display page for samples:
Lists all samples (up to 999 max.) with
processing status
View, delete, omit, or include samples
Display page for measured values:
Shows date, time, ID and values
measured
Display page for results:
Values calculated for a sample
(backweight, loss, ratio1, ratio2)
– Special display page for statistics lets
you define whether lot statistics are
dependent on backweight, loss, or ratio
values
– Press a soft key to view the desired dis-
play page (lots, samples, values or
results)
– To view lot, sample or measured value
data, enter the ID and then press
the corresponding soft key
(
Lot/Sample/Values)
– Define whether printer output is
dependent on the processing status
of the sample
– Printout can contain individual values,
backweighed values and statistics
– User-definable printout format
– The configurations for the weighing
sequence and results are saved
separately for each lot
Purpose
This application enables you to compare
samples before and after a given treat-
ment (such as drying or ashing) and
determine the difference in weight.
There are different procedures available
for this application:
– Collect all data (tare, initial weight, and
backweighing result) for each sample
individually (menu setting “Weighing
sequence: Individual weighing”)
– Save the tare weights and initial
weights for all samples first, then
perform backweighing (menu setting
“Combined weighing”)
– Save the tare weights for all samples
first, then determine the initial weight
of each sample and, finally, perform
backweighing (serial weighing)
