    Med = 0–1,000 ppm High = 0–10,000 ppm. The Model 3000TA is set at the factory to default to autoranging. In this mode, the microprocessor automatically responds to concentration changes by switching ranges for optimum readout sensitivity. If the current range limits are exceeded, the instrument will automatically shift to the next higher range.

    4 Operation Model 3000TA Note: The ranges must be increasing from low to high, for example, if range 1 is set as 0–100 ppm and range 2 is set as 0–1,000 ppm, range 3 cannot be set as 0– 500 ppm since it is lower than range 2.

    To have a replacement cell available when it is needed, TAI recom- mends that one spare cell be purchased 9-10 months after commissioning the 3000TA, or shortly before the end of the cell's one year warranty period. CAUTION: Do not stockpile cells. The warranty period starts on the day of shipment.
