pHix® Compact
EN 4.10 Version 2007
To start a new buffer adjustment, the buffer liquid or electrode should be
replaced and pHix® Compact turned upside-down for at least 30 seconds
before a new buffer adjustment is made.
Depending on the zero point value of the electrode and the preceding buffer
values, the pHix® Compact software automatically determines whether it is the
zero point or the span that needs adjustment.
