Specifications:
- Memory: Supports microSD card for expanded storage
capacity - Usage: Data recording and storage
- Compatibility: Works with CARD Tool and CARD Reader
programs
Product Usage Instructions:
SD Card Installation:
Insert a microSD card into the card slot of the logger to expand
storage capacity.
Data Recording – Chronological Sequence:
- Measurement values are initially stored in RAM 1.
- When RAM is full, data is transferred to internal memory and
simultaneously to the SD card. - RAM contents are then deleted, and the process restarts.
Removing the SD Card:
Do not remove the SD card during data recording to prevent data
loss. Ensure all measurements are saved before removing the
card.
Circular Buffer Mode:
If circular buffer mode is activated, older data in internal
memory may be overwritten but remains saved on the SD card.
Deactivate circular buffer mode carefully to avoid data loss.
Preparing the SD Card:
The supplied SD card is ready for use. No special preparation is
required.
Information Display:
The yellow and green LEDs near the SD card slot indicate
different statuses. Yellow LED indicates errors or resets, while
green LED confirms successful access or insertion.
Reading the SD Card:
Use the MSR Reader program to access and read data from the
internal memory of the logger.
FAQ:
Q: What happens if I remove the SD card during data
recording?
A: Removing the SD card during recording can lead to loss of
unsaved data. Ensure all measurements are saved before removing the
card.
Q: Can I change the SD card from circular buffer mode?
A: No, the SD card is configured as a circular buffer and cannot
be changed.

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.

CAUTION
Risk of data loss! In order to configure the SD card or to read out the data stored on it, 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 SD card.
Data recording – chronological sequence
Measurement data that is written to the internal memory of the logger is also written to the SD card. The following figure shows the chronological sequence.

Measurement values are written to RAM 1, until

The RAM is full. The RAM contents correspond to a page with approx. 500 measurement values.
The RAM contents are written to the internal memory 2 and transferred simultaneously to the SD card 3.
The RAM contents are then deleted and the process begins anew.
The contents of the RAM are also transferred from the internal memory to the SD card when data recording is paused.

Removing the SD card during data recording
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-but-
ton. 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 trans-
ferred 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, this data remains saved on the SD card.n.
CAUTION
Risk 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
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:
LED Yellow
Green
Meaning The yellow LED lights up briefly after a power-on reset (e.g. when connecting the inactive logger to PC) or after unsuccessful access.
The green LED lights up briefly after each successful access to the SD card or after successful insertion.
The yellow warning light on top of the MSR165 illuminates briefly during the status indication if no errors have yet occurred while accessing the SD card.

Reading 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.

· 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 card
· Open the MSR CARD Tool program. · Insert the SD card into the card slot on the PC. · Click Delete. The program only deletes the contents of the file msr.dat but not the file
itself. 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.
