The technical specification of item MEE 73 should read as follows:
Diesel Engine Test Bed: A robust floor mounted engine test stand with modular instrumentation and control system. A regenerative dynamometer includes both torque and speed control together  with direct reading dynamometer digital display. The dynamometer will accept engines up to 4kW shaft power output. Engine speed and all relevant temperatures are also displayed on digital panel  meters on the remote instrumentation console. Air to the engine passes through an intake orifice and pulsation damper. The flow measurement orifice is connected to a panel mounted manometer to allow differential pressure measurement. Fuel flow is measured using a calibrated volumetric fuel gauge. Each of the optional engines are preinstalled on a standard mounting plate that is designed to allow quick and easy installation on the test bed. Each engine is supplied with a suitable fuel tank and supply system with quick release self-sealing fuel couplings. Operator safety is ensured by a range of interlocks and safety cut out devices.
