The Impedo DUO stores calibration constants on EEPROM that can never be lost for
the live of the IC. All systems in the Impedo DUO are protected against power
interruptions and voltage event with an internal LiFePO
4
battery that enables the
instrument to shut down without damaging any system in the instrument. However,
in order to verify that the instrument is measuring correctly, it is recommended to
recalibrate the instrument at least once every five years.
The Impedo DUO does not require recalibration. Calibration
constants will not change and can never be lost for the live of
the product’s EEPROM IC.
