Results For Last Program Compiled; Skipped Scans; Skipped Records; Variable Out Of Bounds - Campbell CR300 Series Product Manual

22.1.3 Results for last program compiled

Messages generated by the data logger at program upload and as the program runs are
reported here. Warnings indicate that an expected feature may not work, but the program will
still operate. Errors indicate that the program cannot run. For more information, see
program errors (p. 174).

22.1.4 Skipped scans

Skipped scans are caused when a program takes longer to process than the scan interval allows.
An occasional skipped scan can be caused by memory formatting as discussed in
(p. 88). If any scan skips repeatedly, the data logger program may need to be optimized or
reduced. For more information, see:

22.1.5 Skipped records

Skipped records usually occur because a scan is skipped. They indicate that a record was not
stored to the data table when it should have been.

22.1.6 Variable out of bounds

Variable-out-of-bounds errors happen when an array is not sized to the demands of the
program. The data logger attempts to catch out-of-bounds errors at compile time. However, it is
not always possible; when these errors occur during runtime the variable-out-of-bounds field
increments. Variable-out-of-bounds errors are always caused by programming problems.

22.1.7 Battery voltage

If powering through USB, reported battery voltage should be 0 V. If connecting to an external
power source, battery voltage should be reported at or near 12 V. See also:

22.2 Understanding NAN and INF occurrences

NAN (not a number) and INF (infinite) are data words indicating an exceptional occurrence in
data logger function or processing. INF indicates that the program has encountered an
