EBME Forums Forums Maintenance Technical Assistance Spirometer Microlab 3300

To check the calibration of the MicroLab a large syringe should be used. This should have a 30mm outlet and be of at least three litres in capacity and preferably six litres. A 3 Litre Syringe is available from Micro Medical as Cat. No. SM2125. The MicroLab should be set up to record a FVC manoeuvre, connected to the syringe with the minimum of adapters. The syringe volume should be injected into the transducer evenly, without pausing.
If, after checking, the MicroLab appears to require re-calibration then please refer to your supplier for service.
