This type of machine was used to check the operations of a vehicle engine. The four connector leads attach to the ignition system of a petrol engine vehicle and analyses the engine timing and volts for the purpose of diagnostics and adjustment. This equipment was generally used pre-1980.
The analyser machine consists of a large red and black metal-clad box shaped device with controls and display gauges on the front. A white panel at the top of the face reads "VANE TEMPO.SCOPE". There are two multivariable analogue meters for displaying Volts, Dwell, Advance, Resistance, and Revolutions per minute. There is also a large CRT display with graph overlay on the leftmost display panel showing Voltage. Several switches and dials adjacent the displays make up the 'Test Selector' and 'Pattern Selector' which allow the user to view different variables. A light-up power switch is located at the bottom right corner of the control panel. At the rear of the unit near the base is connected a grey power cable, fuse, and four coloured seven-pin sockets to connect the leads (blue/green/yellow/black). Also on the rear are two small brackets to fit the cable holder, and two grids of ventilation holes. The whole unit sits on a small metal framed trolley/table. The table is painted grey, has four casters, and has a slide out drawer just under the top.
The connector leads are held in a right-angled metal bracket. Three coloured seven-pin sockets (blue/green/yellow) branch into five connectors at the other end. Two connectors are large rectangular shaped coloured yellow and green; the three other connectors are smaller conical shaped coloured blue, red, and white. The black connector is separate from the others and terminates with a large black plastic tool. The tool has an on/off dial and a large circular opening at the end with bulb inside.
