6.8.2 Calibration Presettings
The calibration presettings can be defined in the parameter settings or adjusted directly in the
Calibration menu prior to the calibration.
Calibration mode
: Presetting of calibration mode, e.g., Calimatic, Manual, Product Calibration, Data
Entry, Temperature
If Calimatic automatic calibration is selected, the buffer set to be used must also be selected.
Calibration points
: Selection of how many calibration points are to be used in the calibration
Drift check
: Sets the sensitivity of the drift check (fine, standard, coarse)

Calibration Timer
When a preset calibration interval expires, the calibration timer generates a message text to indicate
the need for calibration. If “Auto” is selected, the interval is set to 168 h. If “Individual” is selected, you
can select a custom interval.

Note:
If Sensoface is enabled, a neutral smiley is displayed once 80 % of the interval has expired. Once
the entire interval has expired, a sad smiley is shown, a Maintenance Required message is generated,
and the corresponding NAMUR icon
is displayed and the measurement display is shown with blue
backlighting (display color: NE107). If the current outputs are configured accordingly, a 22-mA error
signal is generated.
Adaptive calibration timer
: The time until the next calibration is automatically shortened depending
on the temperature and pH value.
Old sensor = timer expires faster.
The following measuring conditions shorten the adaptive calibration timer interval:
• Temperatures above 30 °C/86 °F
• pH ranges below pH 2 or above pH 12
The message test is displayed in the
Diagnostics
menu:

The calibration timer is reset after each calibration.
