Option Description
Replicate Use this option to start the same titration on the same sample. This is used to study the
sample repeatability by successively analyzing several parts of the same sample. At the end of
each measurement, a window shows the average value, the standard deviation and the
relative standard deviation.
New sample Use this option to start the same titration on a new sample. No standard deviation or
relative standard deviation measurements will be done.
13. Push Exit to go back to the main menu.
