This manual describes the use and precautions of the testo 570 digital manifold.
The testo 570 is a digital manifold designed for commissioning, maintenance, and service work on refrigeration systems and heat pumps. It replaces mechanical manifolds, thermometers, and pressure/temperature charts, allowing users to apply, adapt, test, and monitor pressures and temperatures. The device is intended for use by qualified expert personnel and is compatible with most non-corrosive refrigerants, water, and glycol, but not with ammoniac refrigerants.
The manual covers safety precautions, including handling of refrigerant hoses and electrostatic charging, as well as detailed technical data such as measurement ranges, accuracy, and resolution. It also explains the product description, including display elements and control keys, and provides step-by-step instructions for first steps, performing measurements (pressure, temperature, vacuum, current), saving data, and maintaining the instrument.
