Data logger calibration

Campbell Scientific recommends factory recalibration every three years. During calibration, all the input terminals, peripheral and communications ports, operating system, and memory areas are checked; and the internal battery is replaced. The data logger is checked to ensure that all hardware operates within published specifications before it is returned. To request recalibration for a product, see https://www.campbellsci.com/repair .

It is recommended that you maintain a level of calibration appropriate to the data logger application. Consider the following factors when setting a calibration schedule:

• The importance of the measurements
• How long the data logger will be used
• The operating environment
• How the data logger will be handled

Campbell calibration certificates confirm that an instrument meets or exceeds published specifications and has been calibrated using standards and instruments with accuracies traceable to the National Institute of Standards and Technology, an accepted value of a natural physical constant, or a ratio calibration technique. The collective measurement uncertainty of the calibration process meets or exceeds a 4:1 accuracy ratio. Our facility's policies and procedures comply with ISO 9001 standards.

You can download and print Campbell calibration certificates for many of your purchased products by logging in to the Campbell Scientific website and going to: https://www.campbellsci.com/calcerts . You will need the product's serial number to access the certificate.
