3.9 Nonvolatile Memory
The nonvolatile memory allows the Hydran 201Ti to retain its data even during the
following events:
• Disconnection of the H201Ti’s battery.
• Failure of the H201Ti’s power supply.
• Update of the H201Ti’s embedded software using the Hydran Host software.
The H201Ti’s nonvolatile memory is used to retain the following data:
• The ten parameters of the Hydran 201 sensor (see Section 5.5.4.1 and Section
5.5.8).
• The calibration data (see Section 5.5.9).
