Error number and message
Probable Cause
+702, "Cal: secured"
Attempting to begin adjustments on a
digitizer that is secured.
+703, "Cal: invalid secure code"
The first character of the security
code must be a letter (A-Z), Numbers
and Underscores may be used
following the letter. Punctuation and
spaces are not allowed.
+704, "Cal: secure code too long"
Only 12 characters are allowed in the
security code.
+705, "Cal: aborted"
A remote interface Device Clear
command was received or power was
interrupted during adjustment.
+741,"Cal data lost: string data"
The calibration message string was
lost. Run a full self test to ensure the
digitizer is operational before
attempting to reset.
+747,"Calibration failed;Gain Chan[n] Range[x.x] Coupling[yyy] Filter[zzz]"
+747,"Calibration failed;Offset Chan[n] Range[x.x] Coupling[yyy]
Filter[zzz]
A gain or offset adjustment failed. Run
a full self test to ensure the digitizer is
operational before attempting to
re-adjust.
+748,"Cal checksum failed, internal data"
The checksum failed for calibration
data. Run a full self test to ensure the
digitizer is operational before
attempting to re-adjust.
