- Use the Right or Left arrow keys and select More. Press Enter.

- Use the Right or Left arrow keys and select

This preference is stored in non-volatile memory, so this configuration

is remembered after a power shutdown. If the instrument is cold started, it

will go back to default (not showingg negative oxygen readings).

4.4

Zeroing is not required in order to achieve the published

accuracy specification of this unit.

Zeroing will eliminate offset error contributed by sensor,

electronics, and internal and external sampling system and

improve performance beyond published specification lim-

its.

The analyzer is calibrated using zero and span gases.

Any suitable oxygen-free gas can be used for zero gas as long as it is

known that it will not react adversely with the sample system.

Although the instrument can be spanned using air, a span gas with a

known oxygen concentration in the range of 70–90% of full scale of the

range of interest is recommended. Since the oxygen concentration in air is

20.9 % (209,000 ppm), the cell can take longer to recover if the instrument is

used for trace or less than 1% full scale oxygen analysis immediately

following calibration in air.

Connect the calibration gases to the analyzer according to the instruc-

tions given in Section 3.4.1, Gas Connections, observing all the prescribed

precautions.

CAUTION: If you are requiring 0-10 PPM, a proper exhaust tube
