4.2 pH Calibration Notes
1. A 1-point calibration should be performed at least weekly. In
applications where the sensor junction can become blocked, such as
dairy products, mining slurries etc, a 1-point calibration may have to
be done daily.
2. A full 2-point calibration should be performed at least monthly. Of
course, more frequent calibration will result in greater confidence in
results.
3. All calibration information is retained in memory when the
Aqua-DP
is switched off, even when the battery is removed.
4. The
Aqua-DP
displays the value of the pH buffer that it has
attempted to recognise at calibration. Ensure that the buffer value
displayed corresponds to the buffer that you are using.
