Once correct functioning had been confirmed, then sealing pressure was measured by closing the valve APL and fresh gas flow increased to 10 litres. the pressure generated in the circuit was observed until leaks were presented and sealing pressure was marked once the barometer nee dle became stabilised.
Confirmado el correcto funcionamiento, se procedía a medir la presión de sello cerrando la válvula válvula de límite de presión ajustable y subiendo el flujo de gases frescos hasta 10 litros; se observaba la presión generada en el circuito hasta que se presentaran fugas y, una vez se estabilizaba la aguja del barómetro, se maba la presión de sello.
