You can have your probe calibrated and adjusted at Vaisala world-class facilities, or perform a field calibration yourself using a suitable reference environment.
For information on Vaisala calibration services, visit https://www.vaisala.com.
You can adjust the probe using one of the following options:
- Vaisala Insight PC software (with PC and Vaisala USB cable, see https://www.vaisala.com/insight)
- Indigo transmitters
- Indigo80 handheld indicator
|The Indigo200 transmitter calibration and adjustment instructions in this User Guide revision (M211888EN-E) apply to the 2022 transmitter models with a USB-C (Vaisala Insight PC software) user interface. For calibration and adjustment instructions for the earlier WLAN user interface Indigo200 transmitters, see the earlier revision of this document, M211888EN-D, available at docs.vaisala.com.|
|WARNING When returning a product for calibration or repair, make sure it has not been exposed to dangerous contamination, and is safe to handle without special precautions.|
If you think the device is not measuring correctly, calibration and adjustment is not the first thing to do. Check the following first:
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.
Calibration validity during storage
When the probe is stored indoors in ambient conditions (not in contact with the H2O2 environment or other chemicals), a calibration made to the probe will remain valid for several years. For optimal storage conditions, keep the yellow protective cap on the probe filter.
