PH OPERATION

5.1 Standardization

Because electrodes vary in their response, you must standardize or
calibrate your pH meter and electrode to compensate for electrode
variation. The more frequently you standardize or calibrate, the more
accurate your measurements. Standardize at least daily, or more
often, for accurate results. The meter allows for automatic calibration
with auto buffer recognition for up to 6 buffer values from choice of
either 1 of the 3 buffer groups available or 6 custom pH buffer values
selected from any of these 3 buffer groups (Depending on buffer
selection).

It is recommended that you perform at least 2 point calibration for
optimum meter accuracy.

Always rinse the electrode with tap or distilled water between different
pH buffers to avoid carry-over.

To delete a previous standardization (if performed earlier), refer to the
Section 4.1.12 for details on how to clear pH buffer values.
