Warning: If the power has failed in the “ W
ATER LOG”, the FLASH EEPROM will still contain
the data sampled up to the time of the power failure. Power to the “ W
ATER LOG” must be
restored. Memory pointers will be initialized to the last location in the FLASH EEPROM.
Therefore, extract data using menu option 8 before resetting the “
W
ATER LOG”.
3.2.9 View Data Option
You can examine the data stored in the FLASH EEPROM by selecting option number 9. The
display will show Scan Number, Date, Time, Pressure, Temperature, and Battery Voltage as
shown in Figure 3-19. Up to 16 samples can be displayed on the screen. If more than 16
samples are stored in memory, the “Home”, “End”, “PgUp”, “PgDn”, “ ”, and “ ” keys can be
used to move through the data. A Scan Number can also be entered to help you jump to a
specific location in the data.
