Oxor® III
1.0 INTRODUCTION
The Oxor® III is a portable analyzer designed to detect and display concentrations of Oxygen (O2) gas between 0 and 20.9%. The analyzer is capable
of testing for O2 in both ambient room air, and in the fl ue-gas stream of
fossil-fuel fi red furnaces and boilers (with optional probe assembly).
Ordering Information:
Part No. Description
0019-8112 Oxor III includes 4 ‘AA’ batteries, probe & hose assembly with
integral fi lter, and a hard carrying case.
0019-8113 Oxor III includes 4 ‘AA’ batteries, probe & hose assembly with
integral fi lter, hard carrying case, plus an IrDA printer.
The analyzer detects and displays the presence of O2 by fi rst drawing in a
gas sample from the area being tested by the analyzer’s built-in motorized
pump. The gas sample is next directed into a sensor chamber where the
sample is analyzed for the presence of O2.
A permanent record of the detected O2 level, along with the current time
and date, can be made by using the optional wireless IrDA printer.
A backlight enables the operator to read the display in dimly-lit areas. A
power-saver feature causes the backlight to automatically turn OFF after
10 minutes, and causes the analyzer to shut OFF after 20 minutes of inactivity.

3.0 PREPARING THE ANALYZER
FOR OPERATION
To prepare a new analyzer for operation, you must install four ‘AA’
Alkaline batteries, install the probe (if needed), and set the correct time
and date as described in the following paragraphs.
For your convenience, and to ensure that the analyzer will provide reliable
readings, the O2 sensor was installed and the analyzer calibrated on a
O

known concentration of O2 at the factory.
3.1 Battery Installation
Install fresh batteries as described below. Check the analyzer for suffi cient
charge prior to each use. Replace the batteries if the low-battery symbol
appears in the lower right corner of the LCD. To install batteries:
1. Remove battery cover from back of unit (see Figure 3-1).
2. If old batteries are installed, remove and properly dispose of the
batteries.
3. Observing the polarity markings inside the battery com part ment,
install four ‘AA’ Al ka line bat ter ies.
4. Replace battery cover.

3.3 Front Panel Pushbuttons
Note that a push button may perform several functions, depending on what
screen is being displayed at the time.
I/O • Turns analyzer ON/OFF. There is a 60 second warm-up and
a 5 second turn-off-delay period.
• Places the analyzer into either its Setup or Calibration Mode
when used in conjunction with the ENTER or HOLD button.
• Causes the displayed value to increase or change while in
the Calibration or Setup Mode.
• Causes the displayed value to decrease or change while in
the Calibration or Setup Mode.
ENTER • Starts a test – pump ON.
• Sets up the analyzer to be placed into its Calibration Mode
when held down with the analyzer OFF. (Used in conjunc-
tion with the I/O button.)
• Stores the displayed value and automatically steps to the
next screen when pressed during calibration or setup.
• Displays the O
in the Calibration Mode.
• Aborts turn-off and keeps the analyzer turned ON when
pressed during either the 5 second turn-off-delay period.

HOLD • Freezes the display and stops the pump during a test.
• Starts a printout when pressed twice with the pump running, or when pressed once with the pump OFF.
• Sets up the analyzer to be placed into its Setup Mode when
held down with the analyzer OFF. (Used in conjunction with
the I/O button.)
