6. Calibration and Maintenance
The Model 1000 Series H

S Process Analyzer is calibrated prior to shipment. Only minimal adjustment
should be required at time of commissioning. However, it is highly recommended that a zero and span
calibration be performed twice in the first week of operation to assure optimum system performance. After
that, a recalibration interval of every month is recommended.
Maintenance
When the Acetic Acid Bubbler option is used, the 5% acetic acid solution (or white vinegar) should be kept
near the Max fill mark on the bottle. The level should be checked monthly and the entire solution contents
should be changed every 6 months.
