Chapter 1. Features
and capabilities
1.1 Introduction
The oxy.IQ Panametrics oxygen transmitter (see figure 1
below) is a highly reliable and cost-effective two-wire,
loop-powered transmitter with a linearized 4 to 20 mA
output. It measures oxygen content in ten ppm ranges
(10, 20, 50, 100, 200, 500, 1000, 2000, 5000 and 10000 ppm)
and eight percentage ranges (1, 2, 5, 10, 21, 25, 50 and 100%).
All ranges are user-selectable. This compact transmitter
uses proven sensor technology to accurately measure
oxygen content in a variety of gases, even in hazardous
(classified) locations.
Figure 1: oxy.IQ
1.2 Hazardous location
certifications
When equipped with an optional Zener barrier or
galvanic isolator, the oxy.IQ can be mounted in a
hazardous (classified) location. The oxy.IQ with intrinsically
safe option is certified to USA, Canadian, ATEX, and
international IECEx IS requirements. The standard oxy.IQ
is certified to USA, Canadian, EU ATEX and International
IECEx div2/Zone 2 non-incendive requirements.

Figure 2: Outline and dimensions (ref. dwg. 712-1840)
Note: To avoid collecting condensate that may damage the
oxygen sensor, mount the oxy.IQ in an upright position, with
the sensor manifold below the electronics module.
Install the oxy.IQ by completing the following steps:
1. Remove the oxy.IQ and the separately-packaged oxygen
sensor (see figure 3 below) from the shipping container.
Keep the shipping container and packaging material for
possible future use.
IMPORTANT:
DO NOT open the oxygen sensor package until you are
ready to install the sensor.
Figure 3: Packaged oxygen sensor
2. Remove the sensor manifold by unscrewing it from the
blue knurled nut on the sensor base at the bottom of
the electronics module.
IMPORTANT:
The maximum operating sample pressure for the oxy.IQ is
10 psig except when the ambient air adapter is used for the
sample manifold. The burst pressure of the sample manifold
is 200 psig for all bases except the ISO KF-40 flange adapter.
Since this option is designed for a vacuum flange it cannot
handle sample pressure greater than 20 psig. Be sure the
sample conditioning system is designed to maintain the oxy.
IQ pressure below these limits, and that the oxy.IQ outlet is
vented to atmosphere during operation and calibration.
3. Using PTFE tape as a sealant, connect the sample gas inlet
and outlet to the 1/8” NPT ports on the sensor manifold
(see figure 4 below). Either port may be used as the inlet or
the outlet, as the direction of flow does not matter.

2.2 Wiring the oxy.IQ
To wire the oxy.IQ, refer to figure 14, then proceed as follows:
WARNING!
For IS (intrinsically safe) applications, the
oxy.IQ must be installed with a Zener barrier
(see the top of figure 14). Also, for installations
in a hazardous location, the blue IS cable (p/n
704-1318-02, 10) must be used.
1. Attach the appropriate cable to the oxy.IQ (see figure
5 below). Be sure to align the white arrow on the cable
connector with the white arrow on the oxy.IQ connector,
and then push the top of the cable connector straight
down onto the mating connector on the rear of the
electronics module until you hear it click into place.
IMPORTANT:
Do not rotate the cable connector during installation
(it is not threaded) and do not hold the connector by its
bottom section while pushing it down into place.
IMPORTANT:
To remove the cable, grasp the bottom section of the
connector (the part with the white arrow) and pull it
straight up until the cable comes loose. DO NOT twist the
connector either by hand or with any tool during removal.

Figure 5: oxy.IQ cable and connector
2. Connect the flying lead end of the cable as shown
in the wiring diagram, according to one of the
following conditions:
• No Zener barrier or galvanic isolator:
– For use in non-hazardous areas or
div 2 hazardous areas.
• With Zener barrier or galvanic isolator:
– Required for use in hazardous areas.
IMPORTANT:
To remove the cable from the oxy.IQ electronics module,
simply pull straight up on the lower section of the cable
connector as close to the oxy.IQ body as possible. Do
not pull on the cable or the upper portion of the cable
connector, and do not try to unscrew the cable connector.
2.2.1 Longer cable lengths
Panametrics offers cables in 2 m and 10 m standard lengths.
Longer cable lengths may be used with the oxy.IQ, but these
are not available from Panametrics. If you require a longer
cable, refer to the following figures for the required cable
specifications and construct your own cable for splicing
onto the standard Panametrics cable:
• Standard cable: figure 10 and figure 11.
• IS cable: figure 12 and figure 13.

2.3 Installing an oxygen sensor
To install a new or replacement oxygen sensor in the oxy.IQ,
refer to figure 6 below and complete the following steps:
Oxygen sensor ring
Knurled nut
Sensor base
Sensor manifold
Figure 6: Oxygen sensor installation
1. Disconnect the power from the oxy.IQ.
2. Loosen the blue knurled nut and remove the oxy.IQ
electronics module from the sensor manifold.
If a previous oxygen sensor is already in place,
remove and discard it.
3. Apply power to the unit. The screen will display
“INITIALIZING PLEASE WAIT” for a few seconds before
it begins to display measurement data.
Note: Before continuing with the installation, become
familiar with the procedures for programming and
calibrating the oxy.IQ discussed in chapter 3, initial
setup and operation.
4. Trim the 4-20 mA analog output and set the range
to 0-25% oxygen.
5. Open the airtight package (see figure 3) and remove
the oxygen sensor from the package. To maintain the
oxygen sensor’s energy level, remove the red grounding
tab and immediately install the sensor in the oxy.IQ
6. Orient the sensor so that its gold-plated electrodes
are facing the spring-loaded contact pins in the sensor
base (see figure 6). Firmly press the oxygen sensor
into the sensor base at the bottom of the oxy.IQ
electronics module.
7. Perform an air calibration on the new oxygen sensor
at this time. On the 0-25% oxygen scale, a properly
calibrated oxygen sensor shows a reading of 20.9%
on the display and generates a current of 17.4 mA
at the 4-20 mA analog output terminals.
8. Using the blue knurled nut, attach the oxy.IQ electronics
module with the calibrated oxygen sensor to the
sensor manifold. Rotate the display as desired and
then hand-tighten the blue knurled nut.
IMPORTANT:
Make sure that the o-ring on the top of the sensor
manifold is in place and undamaged. If necessary,
contact Panametrics for a replacement.
9. Begin the flow of the process gas. The analog output
reading will drop as the oxygen sensor adjusts to the
reduced oxygen level. During this time, reset the range
as required.
10. For improved accuracy in the ppm oxygen ranges,
a span gas calibration should now be performed
(see “span gas calibration”).
IMPORTANT:
Sensor life is dependent on the application. High oxygen
concentrations and contaminants such as acidic gases
will shorten the sensor life.

3.3.3.3b Recalibrating an existing sensor
For an existing sensor, continue the air calibration procedure
as follows:
1. Press the enter key to select the NO menu option.
2. As instructed, remove the sensor manifold to expose the
oxygen sensor to ambient air for about two minutes.
Then, press the enter key to continue.
3. A message indicating that the calibration is in progress
will be displayed, and then the calibration data will be
shown. At that time, press the enter key to save the
calibration data and return to measurement mode.
3.3.4 Span gas calibration
Before beginning the span gas calibration, make sure the
oxy.IQ is indicating an O2level less than the span gas value,
to ensure an accurate calibration. Then, start the flow of the
span gas to the sensor. For accurate calibration, the span
gas should have an oxygen content of 70-90% of the range
being calibrated.
To perform the span calibration, complete the following steps:
1. Use the equation below to calculate the expected mA
output that corresponds to the known oxygen content of
the span gas:
4.0 + 16.0 x span gas ppm = mA output
full range ppm
For example, if the span gas contains 80 ppm oxygen
and the 0-100 ppm range is being calibrated, the analog
output should equal 4 + 16 x (80/100) = 16.8 mA.
2. If you have not done so already, start the flow of span gas
to the sensor and allow both the 4-20 mA output reading
and the display reading to stabilize.
3. After the reading has stabilized, press the enter key to
enter the main menu.
4. Press the enter key to enter the calibration menu.
5. Press the key and then press the enter key to select
the span gas menu option.
6. Press the and keys until the measurement agrees
with the span calibration gas value.
7. Confirm that the reading on the display has stabilized, and
press the enter key to save the calibration. Then, press the
cancel key twice to return to measurement mode.
