Page 10: Operation
Never expose the sensor to pressures above atmospheric pressure (0 psi) or you may cause damage to the sensor and/or receive false readings. Damaged Sensors will not provide accurate gas analysis. Inaccurate gas analysis can lead to serious personal injury or death. www.nuvair.com... -
Page 11: Programming Procedures
• If analyzing a gas flow, the Sample Flow Method is the preferred method. The flow rate must equal .5 to 3 L/min at atmospheric pressure. To produce this flow, a Flow Restrictor and Regulator may be required. Contact Nuvair if you need assistance. 4.1. Programming Procedures Keep the Prog button pressed for more than two seconds and then release the button. -
