The values will be written to the sensor and you will be
asked if you want to see the calibration report.
The polarographic D.O. sensor is now calibrated and ready to
take readings. To confirm this, take a reading by selecting the
D.O. sensor in the Navigation tree and clicking the Read
button.
SENSOR SLOPE AND OFFSET
The slope of a properly functioning sensor as calculated
during the calibration process will typically be in the following
ranges, depending on the membrane thickness:
1-mil membrane: between 30 and 67 nA/(mg/L)
2-mil membrane: between 15 and 34 nA/(mg/L)
If the calculated slope is much outside the stated range, the
sensor may need maintenance. Refer to “Sensor Care and
Handling” in Section 13 of the MP TROLL Operator's Manual.
The default offset for Quick Cal and 1-point calibrations is 2
nA. Offsets for 2-point calibrations should fall under 10 nA.
