Error Conditions
The middle area of the screen is also where error
codes are displayed. If the Impulse detects an error
in a measurement or download attempt, a low-
pitched tone issues from the speaker and an error
code displays.
The most common error is that the Impulse simply
cannot find the target. Most other errors are
similarly trivial; correcting them requires only that
you reshoot the measurement you were trying to
take, or try the download again.
You can opt to have measurements with errors
discarded instead of downloaded when in the
automatic download mode.
Code Explanation
