Trace Oxygen Analyzer	Introduction

∙Set LO Alarm Set the concentration BELOW which

an alarm activates.

∙Set HI Range Set the high analysis range for the instrument (up to 0-1,000 ppm).

∙Set LO Range Set the low analysis range for the instrument (down to 0-1,000 ppm).

∙ Span Span-calibrate the analyzer.

Data Entry Keys: Two pushbutton membrane switches are used to manually change measurement parameters of the instrument as they are displayed on the LED meter readout:

Up Arrow Increment values of parameters upwards as they are displayed on the LED readout.

∙Down Arrow Increment values of parameters downwards as they are displayed on the LED readout.

Digital LED Readout: The digital display is a LED device that produces large, bright, 7-segment numbers that are legible in any lighting environment. It has two functions:

∙Meter Readout

As the meter readout, it displays the oxygen concentration currently being measured.

∙Measurement Parameters Readout

It also displays user-definable alarm set- points, ranges, and span calibration point when they are being checked or changed.
