SD card and card slot

The logger is optionally available with a card slot for a microSD card. The SD card offers many times the storage
capacity of the internal logger memory.

Data recording - chronological sequence
Measurement data that is written to the internal memory of the logger is also written to theSD card. The following figure shows the chronological sequence.

Measurement values arewritten to RAM 1, until
the RAM is full.

The contents of the RAM are also transferred from the internal memory to the SD card whendata recording is paused.

Risk of data loss!
In order to configure the SD card or to read out the data stored onit, only the CARD Tool and CARD Reader programs may be used.
Never delete the msr.dat and msr.cfg files that are saved on the SDcard.

CAUTIONCAUTION

Risk of data loss!
Removing the SD card during data recording can have the following
consequences:
The measurement parameters (pages) that have not yet been transferred to the SD card are not saved to the SD card. They are however, written to the internal memory.

Measures for avoiding or minimising data loss:• In Setup or in the Shock assistant, activate the option Start and stop by push-button. Stop data recording by pressing the button before removing the SD card.
• Increase the measurement rate so that the content of the RAM is more frequently transferred to the SD card.

Circular buffer mode

If Setup is used to configure the logger for circular buffer mode, the oldest measurement
parameters in the internal memory of the logger are, if necessary, overwritten. However, thisdata remains saved on the SD card.n.
CAUTIONRisk of data loss!
If circular buffer mode on the logger is deactivated and the internal
memory is full, data recording is paused. In this case no further
measurement parameters are written to the SD card.
To avoid this situation, activate circular buffer mode (see logger
manual or Shock assistant step 4).

Note: The SD card is configured as a circular buffer. This setting cannot be changed.

Preparing the SD card
SD card

The supplied SD card is ready for use with the logger. No special preparation is necessary.
SD cards from third party suppliers must first be configured before they are used:• Open the MSR CARD Tool program.
• Insert an empty, formatted SD card into the card slot of the PC.
• Click Create. The program creates the files msr.cfg and msr.dat.

Note:
Creating the files takes several minutes.
Please do not cancel this process prematurely.

Information displayed about the SD card
The warning lights alongside the SD card slot have the following meanings:
LEDMeaning

Yellow

The yellow LED illuminates briefly each time the SD card is accessed.

GreenThe green LED illuminates for 2 seconds – if the SD card is ok – after the SD card has been inserted.

Yellow and green

The yellow and green LEDs illuminate briefly following a power-onreset.
For example, when connecting a non-active logger to a PC.

The yellow warning light on top of the MSR illuminates briefly during the status indication ifno errors have yet occurred while accessing the SD card.

Large volumes of data are divided into data records that have a maximum of 10,000 pages*.
Only one record at a time can be read from the card.
*10,000 pages correspond approximately to the internal memory capacity of the logger.
Procedure:• Remove the SD card from the logger.
• Slot the SD card into the USB / SD card adapter.

USB / SD card adapter• Plug the USB / SD card adapter into the USB socket on the PC.
• Open the MSR CARD Reader program and click Start.

• Select the desired data record (msr.dat) on the removable drive (SD card) and click OK.

Contents of the SD card

Reading the SD cardSD card• To read further data records click Next. The content window of the SD card will then reappear without requiring the SD card to be re-read.

To read the internal memory of the logger please use the MSR Reader program.

Deleting data records saved on the SD cardse• Open the MSR CARD Tool program.
• Insert the SD card into the card slot on the logger.
• Click Delete. The program only deletes the contents of the file msr.dat but not the fileitself.

Note:
Deleting the measurement data takes
several minutes. Please do not cancel
this process prematurely.

Displaying the memory capacity

In Setup, under Prediction, the internal memory capacity is displayed alongside the memory capacity of the SD card.
Note: The available free capacity shown in Setup under Info and measurement parameters
does not take the SD card into consideration.
