3.1 Contents of Shipping Container
The contents include:
Palm CO Carbon Monoxide Analyzer
A-3388 Adapter, Dome to Sensor
Instructions for Use
A zero and span calibration is performed at
the factory which is documented by the
Quality Control & Calibration Certification,
Section 12, shipped with every Palm CO.
The batteries and carbon monoxide sensor
are installed at the factory so the Palm CO
is ready for immediate use.
Inspect the box and contents for shipping
damage. If any component appears damaged, do not attempt to operate the device
and contact the manufacturer immediately,
Section 9.
3.2 Controls
The analyzer employs a micro-processor that is controlled by three (3)
pushbuttons located on the keypad on the fro nt cover.
CAL () initiates calibration mode and ad justs the reading upward while in
calibration mode.
POWER (⦶) turns the power ON/OFF.
ZERO () adjusts the reading downward while in calibration mode.
3.3 Bump Testing: Prerequisite Gas Tests Prior to Start-Up and Use
Bump testing is recommended before each use of the Palm CO analyzer. To conduct the test, one exposes the sen sor to a g as mix ture of
known carbon monoxide concentration a nd ensures that the response
is within ±3 PPM of carbon monoxide in bump gas.
Due to transportation regulations, w e re comme nd obtai ning a bum p gas of 10
PPM carbon monoxide balance air from local sources.
The device should NEVER be bump tested with a gas containing more
than 25 PPM carbon monoxide concentratio n.
3.3.1 Bump Test Procedure
1. Set up sampling system according to the figure below.
2. Turn on the analyzer.
3. Flow the bump test gas.
4. Wait for the analyzer’s reading to stabilize on the LCD
5. Verify the reading is within ±3 ppm of the CO con cen tration of the bump
gas. If it is not, refer to Section 8 Troubleshooting.
4 Calibration
4.1 Zero Calibration
Performing a zero calibration before every use is not necessary.
Once the POWER (⦶) key is pressed and power is applied, allow the reading
to stabilize for 10-15 minutes in air. The a nalyzer will display a reading of 0
PPM in a clean source of ambient air. However, if the analyzer reading is not 0
PPM:
The most common reason is the analyzer is not located in a clean source of
ambient air which can be remedied by moving to another location.
If the analyzer is located in a clean source of ambient air and the display
reads 1-2 PPM, it is possible the sensor has drifted slightly which can be
remedied by performing a “zero calibration” as described below.
If the analyzer displays a reading greater than 2 PPM, a problem is indi-
cated. In view of the low threshold for CO, the analyzer design has equally
tight limits which considers the initial factory zero calibration. Performing
another in this situation would likely display an “ERR” result. The recom-
mendation here is to contact the factory for assistance.

4.1.1 Procedure:
1. The analyzer should be ON and located in a clean source of ambient air.
2. PRESS the ZERO () key for 3 seconds.
3. The analyzer display will read “Zro”.
4. PRESS the POWER (⦶) key and initiate the zero calibration.
5. The analyzer will display a reading of 0 PPM.
4.2 Span Calibration Considerations
The analyzer has been span calibrated, Section 12, at the factory. This calibration will hold within +
The analyzer should be recalibrated every 12 months thereafter. Contact the
factory for assistance.
2 PPM over a 12 month period.
Use a known source of DRY carbon monoxide span gas
Recalibrate after the battery or carbon monoxide sensor has been removed,
disconnected or replaced.
Calibrate as close as possible to the temperature, pressure and altitude
at which the analyzer will be operated.
4.2.1 Span Calibration Procedure
1. EXPOSE the sensor to a certified span calibration gas between 10-20 PPM
CO with the balance air throughout the entire span calibration procedure.
2. ALLOW the reading on the analyzer’s display to stabiliz e which can take up
to two minutes.
3. PRESS the CAL () key for three (3) seconds.
4. The analyzer display will read “CAL” and initiate the span calibration mode.
5. Release the CAL () key.
6. The analyzer display will blink and read “CAL” for one (1) second before
returning to the last reading.
7. PRESS the CAL () or ZERO () key to adjust the reading of the analyzer
display to the carbon monoxide content of the certified span calibration gas
in step #1 above.
8. PRESS the POWER (⦶) key to complete calibration.
9. If it is not possible to adjust the reading to match that of the calibration gas,
review Section 8 for troubleshooting or contact the factory for assistance.
DO NOT cover the hole on the
side of the black dome adaptor
attached to the bottom of the
Palm CO.
Blocking the “vent” hole causes a
pressure build up on the sensor resulting in erroneous readings.

5 Operation
5.1 Principle of Operation
The device utilizes an electrochemical carbon monoxide sensor intended to
measure carbon monoxide levels in gas streams. Carbon monoxide, diffusing
into the sensor through a gas permeable barrier, reacts chemically at the sensing electrode to produce an electrical curre nt output proportio nal to the carbon
monoxide concentration in the gas phase.
A battery powered state-of-the-art micro-processor converts the sensor’s signal
output, which represents the partial pressure of carbon monoxide in the gas
stream being analyzed. The resulting carbon monoxide reading is displayed by
an easy to read screen that has a resolution of 1 PPM carbon monoxide.
5.2 Application Considerations
5.2.1 Effect of Temperature
At constant temperature, the sensor’s electrical current signal varies linearly
with carbon monoxide concentration. O ver the temperature range of 0-40⁰C,
the output varies approximately ±10% from its value at 20⁰C. For this reason,
it is highly recommended that the analyzer be calibrated at a temperature close
to that of the environment in which it is intended to be used.
5.2.2 Effect of Pressure
The electrochemical sensor measures the partial p ressure of carbon monoxide
in a gas stream to which it is exposed. The sensor is accurate at any pressure
within the rated range of 80-120 kPa, provid ed the ambient pressure is constant during sampling and calibration.
5.2.3 Effect of Humidity
Changes in humidity will produce transients in sensor output that last for about
ten minutes. Therefore, it is recommended that at least ten minutes be provided before taking measurements after a sudden humidity change, which may
occur if the analyzer is removed from a sealed bag of different humidity than
the ambient environment or a dramatic change in the weather. It is not ne cessary that the analyzer be powered on during this period.
8
5.2.4 Effect of Electromagnetic Radiation
Tested over a 26 MHz to 1000 MHz electromagnetic field, the analyzer is susceptible at all frequencies tested except those between 930 and 990 MHz.
Never operate the analyzer near equipment capable of emitting high levels of
electromagnetic radiation. Do not continue to operate the analyzer if the read ing becomes unstable.
5.3 Sampling Procedure
1. Assure that the analyzer is calibrated, giving a stable reading, and is in
sampling mode. Note: Sampling mode is the default screen. Nothing
needs to be done to get to this screen, assuming you are out of all menus
and modes.
2. Open the gas tank until you hear a slight ’hissing noise’
3. Hold the hole at the bottom of the black dome adaptor firmly against the
tank’s gas outlet.
4. Ensure there is a good connection between the dome adaptor and the gas
tank to prevent ambient air from leaking into the g a s being measured.
5. Once the sensor is exposed to the gas stream, allow the reading to stabilize as displayed by the LCD.
6 Maintenance
6.1 Cleaning Instructions
Clean the device only when needed. The carbon monoxide sensor and accessories can be cleaned with a soft cloth dampened with either water or mild
isopropyl alcohol solution (70% isopropy l alcohol solution in water). Allow the
components to air-dry after cleaning.
6.2 Battery Replacement
