Note 1: In auto mode, 90 millisecond temperature compensation cycles occur once every 2 seconds.
Temperature cycles are inhibited if there is critical positive or negative system motion.
Note 2: Remote filter and averaging selections are not stored in EEPROM. EEPROM values will be
loaded at time of unit power up. See Table 3-6 for selection definitions.
