4.3 SENSOR MAINTENANCE

There are no user-serviceable parts on the CS105 barometric pressure sensor. The

manufacturer recommends annual recalibration at the manufacturer’s facility. An RMA number

must be obtained from Campbell Scientific, telephone (801) 750-2342, before returning the

sensor for recalibration.

4.4 POST-MAINTENANCE CALIBRATION CHECKS

After completing all maintenance and adjustment activities, initiate a post-maintenance

calibration check as described in Section 4.1 and record them as the post-maintenance values.

4.5 DOCUMENTATION

Sensor calibrations require several levels of documentation:

CALIBRATION FORMS Calibration forms or the computer laptop Excel spreadsheet

should be completed entirely. Where possible, use the Excel

spreadsheet so that both a hard copy and digital record of the

calibration are maintained. Review and sign all calibration

forms.

LOG NOTES A summary of results and maintenance performed must be

included in the station log notes. Note any abnormalities in

sensor or calibration operation that could affect the quality of

data.

CALIBRATION STICKER An ARS calibration sticker is placed on the sensor, marking the

date the instrument was calibrated and the name of the

technician

who calibrated it.

TRIP REPORT The calibration is thoroughly documented in a written site trip

report.
