The horizontal movement of this end electrode is carried out parallel to the insole of the shoe in its longitudinal direction as the rods 6 and 7 approach or move apart.

The use of vertical or horizontal end electrodes in the device on the results of measuring the electrical resistance of the shoe is practical. does not affect. The presence of these or other end electrodes affects only the operating conditions on the device when shoes are connected to the measuring circuit during laboratory or mass tests, causing a slight decrease in labor productivity with vertical electrodes.

The determination of the electrical resistance of the antistatic shoe using the proposed device is performed as follows.

A weight 19 is placed on the rods 6 and 7 at the rate of ensuring the specific pressure of each of the end electrodes on the insole of at least 4 kg / cm.

Necessary operations with vertical end electrodes.

The tested footwear 5 from the toe side is put on the external core 47 of the nose support 9 and is supported with force with the left hand when the foot electrodes are touched by the end electrodes. At the same time, with the right hand, rotating the handle 21, push the rods 6 and 7 apart, ensuring that the top of the shoe is pressed against the side electrodes. After that, pressing the foot pedal 4, lift the electrode 1 of the base until it comes into contact with the sole of the shoe and the subsequent lifting of the rods 6 and 7 with weights 19 to a certain height. Then, in the circuit of the measuring device 17, the button 18 is pressed and a measurement is taken, 51359761.

Necessary operations with a horizontal-electrode, a rack carrying Iodal end electrodes.

The test shoe 5 is mounted on the base electrode 1, which, after pressing the foot pedal 4, rises to the level of contact with the insole of the end electrodes and lifting the rods 6 and 7 with weights 19 to a certain height. After that, rotating the handle 21 with the right hand, push the STANDS b and 7 apart, ensuring that the top of the shoe is pressed against the side electrodes. Then in the circuit of the measuring device 17, the button 18 is pressed and the measurement is made.

After completing the measurement, rotating the knob 21 in the opposite direction, shift the rods 6 to 7, lower the base electrode 1 to the initial position and remove the shoes from the device.

When it is necessary to test individual sections of the shoe, two liners (not shown) are used, made in the form of insoles and placed inside the product, one of which is made of conductive material and is an electrode, and the other is made of insulating material.

The table shows possible options for connecting to an antistatic shoe device, depending on the purpose of the test.
