Calibration
Calibration Worksheet
e Calibration Worksheet is a record of the calibration for an EXO sensor. e worksheet contains quality
assurance information including date and time of calibration, date of previous calibration, sensor rmware
version, type of calibration performed, standard used, and QC score.
Calibration Worksheets are saved in the Calibration Files folder on the computer (not on the sonde). All
saved Worksheets can be accessed and viewed through the Data menu in KOR soware.
Sample Worksheets
ODO Gain
e ODO gain is a diagnostic value recorded on the Calibration Worksheet and used for advanced diagnostic
purposes. e nominal value is 1, and accurate calibrations will only slightly deviate from this number.
1-point calibration of specic conductance
on EXO conductivity/temperature probe
1-point calibration of percent saturation
on EXO optical dissolved oxygen probe
