17.7.1 Processor reset

To reset the processor, simply power cycle the data logger. This resets its short-term memory,
restarts the current program, sets variables to their starting values, and clears communications
buffers. This does not clear data tables but may result in a skipped record. If the data logger is
remote, a power cycle can be mimicked in a Terminal Emulator program (type REBOOT <Enter>).

17.7.2 Program send reset

Final-data memory is erased when user programs are uploaded, unless preserve / erase data
options are used and the program was not altered. Preserve / erase data options are presented
when sending programs using File Control Send command and CRBasic Editor Compile, Save
and Send.
TIP:
It is good practice is to always retrieve data from the data logger before sending a program;
otherwise, data may be lost. See
When a program compiles, all variables are initialized. A program is recompiled after a power
failure or a manual stop. For instances that require variables to be preserved through a program
PreserveVariables()
recompile, consider
and User Settings. Entries in User Settings are not erased when a program is recompiled.
User Settings can be entered manually in Device Configuration Utility in the Settings Editor >
User Settings tab, or they can be written through a CRBasic program using the
instruction.
NOTE:
User settings are stored in flash memory. To avoid corrupting the flash memory, edit these
settings infrequently.
