Chauvin Arnoux C.A 852 Notice De Fonctionnement page 10

Our guarantee is applicable, unless otherwise stated, for twelve months following the date of supply of
the equipment (extract from our General Sales Conditions, available on request).
The CA 852 pressure gauge is ideal for measuring pressure levels in air-conditioning installations, medical
equipment and pneumatic control systems.
It measures relative pressures – pressure measured in psi in relation to atmospheric pressure – and
differential pressures – difference between two pressures.
5 measurement units are available for selection: psi, bar, inH
„ The pressure gauge should only be used by people qualified to work on pressurized circuits. The
manufacturer and its distributors disclaim any responsibility for damage resulting from improper
unqualified use of the instrument. Refer to the general terms of sale.
„ The battery compartment must be closed before using the pressure gauge.
„ Ensure that no dust or foreign matter penetrates inside the pressure gauge.
„ To avoid damage due to overpressure, comply with the measuring range of the pressure gauge.
„ To prevent corrosion of the pressure sensor, the pressure gauge must not be used with corrosive gases.
„ To prevent a sudden pressure drop in a pressurized circuit, close valves to isolate the portion of the
circuit where the pressure gauge is to be mounted or removed and slowly release the pressure before
attempting to open this portion of the circuit.
