This circuit was found in a 1978 British magazine, but it can still be mounted by simply replacing the BC107 transistors with current equivalents such as the BC547. The circuit provides an indication of the force with which the electrodes tighten, which are nothing more than metal rods. In the circuit the connection of these rods is indicated as handgrips. Scale adjustment according to force is done in VR1.
