Memory functions
W-4510 configurations save in three different memory areas. These areas are:
1.
Lower RAM (active)
2.
Upper Ram (with battery-backup)
3.
EEPROM (non-volatile)
Lower RAM is the memory that the gauge uses during operation. If you make changes to the
gauge configuration or calibration that you want to save, then you must save these changes
to the EEPROM. If you do not save to the Upper RAM and EEPROM, the new information is
not available after powering off. When you save to the EEPROM you save the configuration
and calibration changes that you want to keep and this information loads down to the Upper
RAM and Lower (active) RAM at power up.
