Trace Oxygen Analyzer

Introduction 1

 

 

 

 

 

 

Set HI Range Set the high analysis range for the instrument (up to 0-9999ppm).

Set LO Range Set the low analysis range for the instrument (down to 0-10ppm).

SpanSpan 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:

UpArrow Increment values of parameters upwards as they are displayed on the LED readout.

DownArrow 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 setpoints, ranges, and span calibration point when they are being checked or changed.
