CRC should not be disabled, but the following scenarios are an exception where
CRC check can be disabled:
a)
Communication error occured while inititating a new measurement sequence.
b)
A communication error occured after data retriaval, while updating status in the
recorder.
c)
A communication error occured while putting the recorder to sleep.
d)
A communication error occured while updating status in the recorder upon a
POR (Power On Reset) error detection. When connecting to the recorder and
POR error is detected, a new status is initiated in the recorder and the RAM
data is reset.
e)
Repeated CRC error occurs and the above does not apply/has been checked.
This may though produce errors in the RID file, which again may produce errors
in the conversion of data.
1.3
Disable CRC Check
In case of persistent CRC check error, the CRC check can be disabled:
1.
Go to Settings Connection and disable the Perform CRC test
when retrieving RID.
2.
Try connecting to the recorder Recorder Connect.
3.
If connection is OK, then examine the RIT file for possible errors.
These possible errors may manifest themselves as very high (>E20)
or very low (<E-20) calibration constants. Other errors may be
abnormal times/dates and abnormally high measurement sequence
number in the RIT file. Usually SeaStar will come up with a warning if
the calibration constants or time/date is not normal. If the RIT shows
signs of these error, please request recorder backup file (RBD) from
Star-Oddi.
4.
If the recorder has been measuring data, try to retrieve the data
Recorder Retrieve Data. If data cannot be retrieved there is fault
with the PC com port, the communication cable or the recorder. If
data retrieval is OK, continue to step 5.
5.
Make a short measurement test and start the recorder in a new
measurement sequence Recorder Start New Measurment
Sequence.
6.
Connect to the recorder after the short measurement test, Recorder
Connect. The CRC check is automatically enabled. If a
communication/CRC error occurs, then there is fault with the PC
com port, the communication cable or the recorder. If this is the
case please contact Star-Oddi
7.
Retrieve data from the short test Recorder Retrieve Data.
Analyse the data and verify that the values are correct.
