To minimize the risk of breakdown, even if the dimensions of the sample chamber and electrodes become further smaller.
The removable data storage device for a measuring instrument which uses a test strip to measure the concentration of an object to be analyzed in a liquid sample is configured, to include a carrier having a proximal and distal end, and including a circuit board. The circuit board has electrical contacts, including a ground contact and a voltage supply contact electrically connected to the measuring instrument at predetermined positions. The circuit board includes a nonvolatile memory storing data used by the measuring instrument. The data includes constants used by machine language instructions stored in the memory of the measuring instrument. When the removable data storage device is inserted into the measuring instrument in the preferred orientation, the ground contact becomes electrically connected to the measuring instrument before the voltage supply contact; and when the removable data storage device is removed from the measuring instrument, the ground contact becomes electrically disconnected from the measuring instrument after the voltage supply contact.
