Temperature Calibration - Seko K500 TB Manuel D'installation

The "standard" calibration curve can be restored at any time by accessing the "Reset
Defaults" sub-menu. This operation will permanently delete any "manual" calibration curve
settings which have been applied.
MANUAL CALIBRATION PROCEDURE (EXAMPLE BASED ON 4 POINTS)
The creation of a 4 point calibration curve requires approximately 5L of activated sludge and four
containers made of black plastic. The minimum useful volume of the containers must be 2 L. The
first container must only contain clean water to verify the zero point. The second must contain
activated sludge diluted at a ratio of 1:1 (1 L of sludge + 1 L of water). The third must contain non-
diluted activated sludge. The fourth container may contain the activated sludge resulting from the
partial thickening of a volume of 3 L.
Insert the measurement probe into the various containers and record the values in millivolts (mV)
that appear on the display (at the centre on the top). Wait for the values to stabilise before recording
them on a sheet of paper.
Important: The sludge must be continuously mixed during this operation in order to make sure that
it is distributed in a uniform manner within the container.
The samples utilised must be subsequently analysed in a laboratory in order to determine their exact
content of dry matter (SOLIDS).
At this point, the pairs of values can be inserted in the "Edit Settings" sub-menu.
SPAN
This function appears in the calibration menu whenever the configured probe is of a FREE
typology.
The SPAN value is used to vary the measurement by +/-50% (with any unit of measure).
