Manual Alignment and Recording Correction Values
In the sequel, the test equipment and the instrument preparations required to manually align the ZVB
and each of the alignments are described.
Preliminary remarks
The analyzer must be allowed to warm up for at least 30 minutes before alignment. This is the only way
of ensuring that the guaranteed data are met.
