Calibration Type
Function
Sensors Supported
1-Point Sample
Set measured reading to desired reading.
Changes offset. Best done at high end of range.
All
2-Point Buffer
Automatically sets measured readings to closest
buffer standard. Two points separated by more
than 2 pH units. Buffer standards are selected in
the configuration menu. Changes span and offset.
pH
Zero
Set measured reading to zero. Measured reading
must be close to zero.

Adjust measured reading to calculated reading of
oxygen in air with pressure and salinity
configuration settings as well as temperature
reading. Assumes sensor is placed in air.

Accessed through digital network.
1-Point Buffer
Automatically sets measured pH reading to
closest buffer standard point. Buffer
standards are selected in the configuration
menu. Changes offset.
