Figure 3-23. Diagnostics Option
Figure 3-24 and Figure 3-25 show the results of the diagnostics. The first line tests the CONFIG
register to see if the processor's COP timer is enabled. The diagnostics software in the
“
W
ATER LOG” then checks the program EEPROM memory for a correct checksum. The
software then tests the RAM Memory, FLASH EEPROM memory, EEPROM user notes, and
performs a measurement that returns pressure, raw pressure voltage, temperature, and raw
temperature voltage. The results of the tests will be shown on the screen. After the tests have
completed, you can press any key to return to the main menu.
