electrode upside-down.
The buffer adjustment mode is initiated after app. 30 seconds - this is indicated
by the LED with 3 short flashes every 5 seconds.
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 calibration.
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 liquid,
the transmitter will enter alarm mode indicated by a flash every second.
