Would have been used by staff and students of electrical Engineering at the School of Mines, Lydiard St. campus up until the start of the Mount Helen campus E building third floor. The meter would have had limited use in classes until 2009. This Wattmeter became part of the historical collection in 2011 after the movement of Engineering out of the E building. In working condition and a good example of early 20th century electrical instruments.A polished natural timber case with partial flip top lid and leather carry handle, housing a single phase AC Wattmeter, rated at 170 volts , 30 amps Scale 0 to 5 kilowatt. Serial no :210088Schematic diagram on inside lid showing how to connect the Wattmeter to measure a 3 phase balanced load. Paper sticker on top "1/92" Information for voltage and current ranges painted with white paint on left hand side by Voltage terminals Voltage terminals labelled A and N Also white on black "W8" on same surface Aluminium plate "67" on right hand side near current terminals which are engraved To A and Ti A to indicate current flow direction Aluminium sticker with Ballarat CAE Electrical Engineering by carry handleeverett instruments, single phase, wattmeter, electrical, scientific instruments

Would have been used in electrical engineering laboratory experiments. Slip inside of lid indicates that the instrument would have been checked at times for accuracy of readings. This was checked and passed on 28 November 1959.Wattmeter, portable, in varnished wood case with leather strap handle. Hinged lid with calibration chart inside the lid. Range - 0 to 1.5.
