The “Differential Weighing” Application
156
When the function key is pressed, the prompt opposite appears. When you respond with
yes, the tare weight of the first sample is copied for all further samples in the current series
(as long as no tare weight has already been defined for these samples).
Differential weighing without tare
For certain applications in which no tare vessels are used (e.g. filter weighing), you can
suppress tare determination for the whole series. This saves an operating step.
Before you can process a series with no tare value, the “No tare” function key must be
activated (section 12.3.2).
After pressing the “No tare” function key, the balance displays a prompt. Before you confirm
this, please consider the following:
If you suppress the tare process, this applies for all samples in the series for which no
tare value yet exists (existing tare values are retained, all tare values that have not yet
been defined are set to zero). If you nonetheless want to enter a tare value for a particular
sample in this series, you first need to delete all the measured values for that sample.
