9.2 Error messages
Probes can communicate with error messages when they are connected to Indigo80 indicator
or Insight software. The messages are categorized according to the severity of the status:
• Critical errors are fatal to the operation of the device. It may not be able to respond to
communication at all, and will not measure correctly.
• Errors prevent normal operation of the device. Depending on the problem, errors may
resolve themselves. For example, a completely wet humidity sensor may cause a humidity
measurement error.
• Warnings do not prevent normal operation but may indicate possible problems.
• Status indicates a known state of the device.
