Instrument fails to log:
•
Verify the LED indicator status:
o
With the instrument in air (NOT submerged), insert the red shorting plug. The
LED indicator should show solid green indicating the instrument is charged and
ready.
Note: If SV
•Xchange
, CT
•Xchange
, or C
•Xchange sensor
s are not
installed, the instrument will begin logging in air.
o
Place the instrument’s sensors in water. The LED indicator should remain green
and begin flashing, indicating the instrument is charged and logging.
▪
If the indicator shows red, charge the battery.
▪
If the indicator does not light up, the instrument is not operating
correctly. Continue with the remaining troubleshooting items.
•
Allow at least two sample periods for the instrument to detect that it is immersed.
•
Is the red shorting plug firmly seated in the instrument?
•
Are the batteries dead (LED light does not illuminate when shorting plug is installed)?
•
Were the sound velocity increment, pressure increment and/or sample rate settings set
to values that could prevent logging?
•
Was the log file name set correctly?
•
Is the connector damaged, dirty, or corroded?
•
If all previous steps fail, reset the instrument. Send an
INIT
command to the instrument
to re-initialize the memory.
Note: The
INIT
command will completely erase all settings stored on the instrument.
Instrument generates noisy data:
•
Is the connector damaged, dirty, or corroded?
•
If connected to external power, is there noise on the power supply? Switch-mode power
supplies are common sources of noise.
•
Nearby EMI sources such as electric motors can create noise. If possible, move the
instrument and its cables away from the noise source.
•
Are the sensor/s clean?
•
Are there bubbles on or in the sensor/s?
•
Are the sensor/s damaged?
•
Is there something nearby affecting the water temperature?
Battery fails to fully charge:
•
Is the power adaptor connected to the data/power cable?
