The antagonistic pair has an elastic nature and the presence of dampers makes the motion of the pointer similar to the one of an ammeter. The unique geometric configuration of the mechanic device allows to amend the trace, that based on the motion of the moving equipment should develop according to an arch of a circle. The ammeter-like range of the tool is of 85A and the volumetric one of 1,3Kg.<br >The recording gear is made up of a roller system, placed in rotation with a clockwork mechanism activated by a spring, charged electrically, that drags a roll of paper divided into millimeters and a diagram allowing them to pass under the nib.\nIn 2001 the tool underwent a CESA restoration, carried out by Gregorio Chiarenza of the Elettrotechnics Department.<\/p>\n<h2  class=\"\">Technical Data Sheet<\/h2>\n<p  class=\"\" style=\"text-align: left;\"><span  style=\"font-weight: bold;\">Name<\/span>: Watmeter recorder<br ><span  style=\"font-weight: bold;\">Category<\/span>Wattmeter recorder with automatic balancing with a Lord Kelvin\u2019s scale equipment<br ><span  style=\"font-weight: bold;\">Manufacturer<\/span>: Westinghouse Electric &amp; Manifacturing Co.
