Calibration means comparing the measurement output of the device to a known reference, such as a known environment in a calibration chamber or the output of a reference instrument. Correcting the reading of the device so that it measures accurately is referred to as adjustment. |
Sensors and measurement electronics are fully contained in the replaceable probes. This allows the probes to be calibrated, adjusted, and replaced as needed. Probe serial number and calibration information (calibration date and information text string) are stored in the probe. If a probe is replaced or the calibration information in the probe is updated, VDL200 automatically sends the new information to the monitoring system.
The calibration frequency depends on the application and your compliance requirements. Vaisala recommends having the probes calibrated and adjusted once a year by Vaisala Calibration and Repair Services. See vaisala.com/calibration.
