Meter Setup Menu Features

Automatic Blank Correction

The Orion Star LogR pH/ISE meters have an ISE automatic blank correction feature
that uses an algorithm to compensate for the non-linearity of the ion selective
electrode in low-level standards and samples. Since the automatic blank correction
feature requires the use of a set of non-linear equations that can only be calculated
numerically, the user cannot analytically verify the calibration and the average slope
value that is displayed on the meter may be outside of the slope range that is
specified in the electrode user guide. In applications were analytical verification is
required, the automatic blank correction feature should be turned off.
