Calibration Worksheet
The Calibration Worksheet is a record of the calibration for an EXO sensor. The worksheet contains quality
assurance information including date and time of calibration, date of previous calibration, sensor firmware
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 software.
Sample Worksheets
1-point calibration of specific conductance
on EXO conductivity/temperature probe
ODO Gain
The ODO gain is a diagnostic value recorded on the Calibration Worksheet and used for advanced diagnostic
purposes. The nominal value is 1, and accurate calibrations will only slightly deviate from this number.
