They represent:

1. Photo 1 The measuring card 2. Photo 2 The data card 3. Photo 3 The data processing card 4. Photo 4 The data slide 5. Photo 5 The experiment folder.

Regarding 1. The measurement card in Figure 1 is equipped with punched-out shop windows which, for example, can have the shape of a circle or rectangle, depending on the intended use. This card is used here for printing or drawing

and represent resistances and can be connected to one another by printing or by drawing in lines.

The punched-out shop windows a and b serve here as a resistor and a measuring instrument, c as a display of the measurement sequence and d and e as a measurement display when using a data slide Fig. 4.

Regarding 2. The data card in Figure 2 is intended for printing or drawing in the precalculated measured values, whereby the printing or drawing of these values in the data card is to be determined in such a way that the data and the shop window can be matched accordingly; consequently, both cards are of the same format. In this way, the measurement card image 1 and the data card image 2 can be combined by placing the data card under the measurement card and shifting it against each other in the step of the intended individual measurements (display of the measurement sequence in window c) so that in the shop windows of the measurement card the precalculated results appear on the data card in a programmed manner.

Re 3. The data processing card in Figure 3 is used to register the precalculated values that appear in the shop windows of the measurement card during the simulation measurements on the data card, step by step; it is therefore used to print or draw in a predetermined table in which the categories are arranged in such a way that the entries of the measurement results are clearly arranged at the end of a series measurement

and formulas can be recognized.

4. The data slide is shown in Figure 4 and consists of a strip bent at right angles, e.g. made of cardboard or sheet metal, with a short and long arm. The short leg is used to slide along the edge f g of the measurement card Figure 1 and the long leg of the data slide is used to insert under the measurement card. The long leg under the measurement card is used to print or draw in measurement numbers and measurement data for shop windows d and e. For this purpose, the center of gravity of the shop window is embossed in the measuring card on the long arm of the data slide and this also applies to the data card.

To 5. The experiment folder in Fig. 5 is used to hold the measurement card in Fig. 1, the data card in Fig. 2 and the data slide in Fig. 4. The data card with the imprint or drawing of the precalculated measurement results in Fig. 2 is on the left Half of the folder in Fig. 5 should be under the measurement card, whereby the measurement card can be moved gradually along the data card. For this purpose, parallel rails m and n are provided for guiding the measuring card and parallel rails k and l for holding the data card in place. The data slide in Figure 4 slides along the map f g of the measurement card in Figure 1 and the rail k of the folder in Figure 5, whereby the data slide is guided in the horizontal direction in the experiment folder. This can also be implemented and applied analogously in the vertical direction.

The experiment folder can also be designed in the form of a light box, in which a light source is provided, which is equipped with a plug cord in connection with a push button switch. A suitable reflector is also located inside the housing to achieve a more even distribution of light from the transparent cover. Another implementation option instead of the experiment folder would be a box in the form of a measuring device in which the data card represents a reel-up tape for several series measurements, which runs over reels and on which the measurement card, each for a series measurement, is placed in rails. and can be exchanged.
