The small connecting pins on the bottom of the flow sensor may become blocked. It is possible to clear these blockages in two ways.
Simple water vapour blockages may be cleared using compressed air, such as the gas used for calibration. Disconnect the gas supply line from the back of the Ergostik and use the gas pressure to blow through the holes in the flow sensor to clear any moisture.
If for any reason there is a more severe blockage it is possible to use the end of a paperclip to gently clear the holes of the flow sensor. Ensure the paperclip doesn’t come into contact with the orifice inside the sensor.
The Variable Orifice within the FlowSensor must be free from obstructions or residue in order to function accurately. If after disinfection & drying, the FlowSensor membrane does not look clear repeat the disinfection & drying process.
N.B. DO NOT UNDER ANY CIRCUMSTANCES INSERT ITEMS INTO THE FLOWSENSOR TO REMOVE RESIDUE. THIS WILL CAUSE IRREPERABLE DAMAGE TO THE MEMBRANE.
