The Active Zero Offset feature automatically compensates for gradual zero baseline cleanup, ensuring accurate low ppb O2 readings.
Active Zero Offset
The Active Zero Offset starts at 0.00 ppb and increments automatically to adjust readings. It resets to 0.00 ppb after each User Zero Calibration. It operates effectively when the zero baseline falls at less than 0.1 ppb/hr. If the offset reaches 3 ppb, a warning prompts a zero calibration. The maximum offset is 3 ppb, and further downward trends result in negative readings until recalibration.

Sample Gas Preparation and Delivery
The DF-760 consists of two analyzers with a common gas delivery system. Key parameters like flow, pressure, and background gas affect performance. Proper moisture analyzer operation depends on sample gas pressure, with specific pressure ranges for different gases. The oxygen sensor is calibrated at a flow rate of 1.0 slpm in N2 and should be operated within 0.5 to 1.5 slpm for accuracy.

Flow Rate Effects on Sensor Performance
Changes in flow rate minimally affect moisture cell performance but can affect oxygen readings. The oxygen sensor is recommended for leak detection due to its sensitivity to flow changes. A simple test can identify leaks by observing oxygen readout at different flow levels.
