not vary from sample to sample. Instead of zero the pretare value is displayed (as a negative value)

balance pan to determine the weight of the sample.

Check the Pretare value by pressing and holding the key for approximately 3 seconds
during weighing.
To set a pretare value using the optional AKB-301 Application Keyboard, press the [Pretare value] and
the
key at the same time. Use the AKB-301 if you have to change the Pretare value
frequently.
