If pHix® Compact is dipped into a buffer solution with a value of 4, 7 or 10 pH,
pHix® Compact automatically searches for a buffer with one of those values.
When the correct value is found, the zero point or span will automatically be set
to the right value. The LED will give one short flash every 5 seconds for
indication of a successful adjustment.
pHix® Compact is now ready to be put into service or for another buffer
adjustment with another pH value.
For a new buffer adjustment to another (or same) pH value, simply turn pHix®
Compact upside-down again with the electrode tip pointing upwards for
approximately 30 seconds. When the LED gives three short flashes every 5
seconds, the above procedure is repeated.
If pHix® Compact cannot find the correct pH value for the selected buffer
solution, the transmitter will enter alarm mode indicated by a flash every
second.
To start a new buffer adjustment, the buffer solution 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.
