Stratos®Pro A4... PH User Manual

Calibration
Please note:
• All calibration procedures must be performed by trained personnel.
Incorrectly set parameters may go unnoticed, but change the
measuring properties.
• The response time of the sensor and temperature probe is
considerably reduced when the sensor is first moved about
in the buffer solution and then held still.
• The device can only operate properly when the buffer solutions
used correspond to the configured set. Other buffer solutions, even
those with the same nominal values, may demonstrate a different
temperature response. This leads to measurement errors.
When using ISFET sensors or sensors with a zero point other
than pH 7, the nominal zero point must be adjusted each time a new
sensor is connected. This is important if you want to obtain reliable
Sensoface messages. The Sensoface messages issued during all further
calibrations are based on this basic calibration.
