Troubleshooting
6.3 External Components
Symptom
The Surveyor 4a stirrer or circulator does not operate
correctly.
6.4 Communications
Symptom
For Surveyor 4a software V1.10 and lower, the Surveyor 4a
appears to lock-up if an XMODEM file download is attempted
from Terminal>Files>Download and the attached Series 3
Sonde is not transmitting an XMODEM spreadsheet
importable file. Under these circumstances, the Abort and
power keys are ignored. This situation will only develop if the
Surveyor 4a download starts to initiate the Series 3 Sonde
file download.
Real-time readings from the Sonde are not displayed on the
screen, or symbols instead of readings are displayed after
connecting the Sonde to the Surveyor 4a.
6.5 Surveyor 4a Software Symbols
The software symbols used for the Sonde parameters will also appear on the Surveyor 4a display.
Note that "N/A" will be displayed as "N" on the Surveyor 4a screen.
Symbol
Indicated that the reading is within expected range and does not present any
(Blank)
anomalies.
Indicated that the reading cannot be taken for the parameter, it is out of
range (above or below the Sonde measurement capability). For instance, if
#
the Surveyor 4a battery voltage is out of range, the instrument will display #
signs on the screen in place of the reading.
Indicated the Surveyor 4a is interrogating the Sonde for information, or that
X
the parameter will keep a fixed value and will not update
Indicates that the Surveyor 4a is interrogating the multiprobe for information,
------
or that the parameter is not available or off-line (the reading will not update).
Reminder to set the time after changing the clock battery or parameter has
*
never been calibrated after a reset.
After D/T, it indicates that the Surveyor 4a clock is not functioning.
&
After IB% Svr4a:%Left, it indicates that Surveyor 4a battery was removed.

Possible Solution
The Sonde stirrer or circulator needs to be serviced. Refer to the
maintenance chapter in the Sonde User or Operating Manual.
Possible Solution
To recover from lock-up, disconnect the underwater cable from
either the Series 3 Sonde or the Surveyor 4a, then press Abort or
wait for the transfer to time-out.
Check the history line to determine how the Surveyor 4a is
connected (NoConn, Series4Sonde, Series3Sonde, Charger, PC,
or Terminal). Depending on the operation to perform, choose one
of the connection types.
Check cables and connections. Check baud rate settings.
Important Note: If you are using 100 meter or longer cable and
decide to switch to 19200, you may lose communications with the
instrument. We recommend connecting the Sonde and Surveyor
4a with a shorter cable before switching the baud rate.
