4.2 Using the Function and Data Entry Buttons

When one of the function buttons is being pressed, the analyzer is in the Setup mode or the Calibration mode.

The four setup function buttons on the analyzer are:

SET HI ALARM

SET LO ALARM

SET HI RANGE

SET LO RANGE

The Calibration mode button is:

SPAN

The data entry buttons (Δ and ∇) adjust the value displayed on the TRACE OXYGEN meter while one of the function buttons is being held down.

Δ : Increments the displayed value upwards.

∇ : Increments the displayed value downwards.

Any of the functions can be selected at any time by pressing the appropriate button.

Each function will be described in the following sections. Although the operator can use any function at any time, the order chosen in this manual is appropriate for an initial setup.

4.3 Setting the Analysis Ranges

The two user-definable analysis ranges are both capable of being adjusted from 0-10 ppm to 0-1,000 ppm oxygen concentration.

The analyzer automatically switches from the LO range to the HI range when the oxygen concentration reaches the LO range full- scale value. It will switch back to the LO range when the oxygen concentration falls below the LO range full-scale value

Note: The HI Range set-point MUST be set at a higher concentration than the LO Range set-point.
