Pagination or Media Count:
The device contains an additional series connected relay element, intergating network with series connected diode and resistor tied in parallel with the main resistor of the integrating network, and a summing circuit. The input of the relay element is connected to the output of the rectifier, and its reference voltages are respectively the zero voltage and a voltage which is proportional to the maximum change in the coefficient of static friction. The second input of the auxiliary summing circuit and serves as the input for information on the value of the maximum coefficient of static friction.
