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.
