Generally, all VISOCOLOR
Hence, if you switch tests, you need to perform a new zero mea-
surement. If you run a test sequence for different parameters from
the same sample, you can set one zero measurement for all subse-
quent VISOCOLOR
a zero once.
If the 0-Set function is activated and you have performed a zero
measurement, you can select a different test, insert the measuring
tube directly and run the measurement via
new zero, it will overwrite the first one and be stored as the next
superordinate zero value.
Once you turn-off the instrument, the 0-Set value is lost and you
need to measure a new zero.
By default, the function is not active, but you can turn it on or off,
respectively in the settings
Note: We recommend to only use the same zero measurement as a
basis for different measurements if the tests are performed from the
same sample, or if the samples are very similar.
If you are not sure if the similarity is adequate, we always recom-
mend measuring a new zero for our VISOCOLOR
