Trace Oxygen Analyzer Introduction
Teledyne Analytical Instruments 3
Function Keys: Seven push button membrane switches are used to
select the function performed by the analyzer:

Set Alarm 1: Set Alarm1 Hi or Low, and the concentration at
which alarm 1 activates.

Set Alarm 2: Set the Alarm 2 Hi or Low, and the
concentration to which alarm 2 activates.

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).

Span: Span calibrate the analyzer.
Data Entry Keys: Two push button 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 setpoints, ranges, and span calibration point
when they are being checked or changed.
