MMC/SD Troubleshooting

The MMC or secure digital (SD) card is not required for operation in detectors equipped with datalogging. However, the following two screens display if the card is not inserted.

A new MMC is automatically formatted when it is inserted in the detector. When the detector is activated, it begins the self-test and then displays the following screen.

Restoring Datalog Files

If the MMC has been accidentally reformatted or erased by the computer application, the following screens display when the card is inserted into the detector.

Warning

Only erased data files can be restored using the detector. Computer applications sometimes write data over erased files and that data cannot be restored by the detector.
Always create back up files on the computer.

To restore the logfile, complete the following:

1. From the detector, press to restore the log file. The following screen displays.

If the detector successfully restores the log file, the following screen displays and the start-up tests continue.

2. Using the computer, verify that the logfile has been restored. When the normal operating screen displays, deactivate the detector.
3. Remove the MMC and insert it into the card reader.
4. From the computer desktop, double-click My Computer to view the list of drives.
5. Double-click the Removable Disk drive to access LOGFILE0.CSV. Open the log file and verify that the data has been restored.

If LOGFILE0.CSV does not display, ensure that the MMC is installed in the card reader correctly and that all connections are secure.

6. After verifying that the log file has been restored, re-insert the MMC into the detector.

Reformatting the MMC

To reformat the MMC, complete the following:

1. Insert the MMC into the card reader.

2. From the computer desktop, double-click My Computer to view the list of drives.

3. Double-click the Removable Disk drive to access LOGFILE0.

4. Select LOGFILE0 and delete.

5. Reinsert the MMC into the detector.

6. Activate the detector. The start-up self-test begins and the following screens display.
