1. Calibrate the oxygen meter to check whether the meter measures the accuracy of the oxygen probe life.
2. Whether the sampling line of the nitrogen meter is off or not smooth, adjust to normal
3. The nitrogen output of the nitrogen generator is more than the rated gas volume. The actual gas volume calculation method is if the glass rotor flow rate or the metal rotor flowmeter: the actual flow reading = √ pressure +1 × the reading on the flow meter is the pot street flow Actual flow reading = (pressure +1) × reading on the flow meter
