1 Introduction
Congratulations on your purchase. These Instructions for Use describe the
precautions, set-up, operation, maintenance, and specifications of the Palm
CO Carbon Monoxide Analyzer.
This symbol means CAUTION – Failure to read and comply with the
Instructions for Use could damage the device and possibly jeopardize
the well being of the user.
Users must read the following statements as they are essential to reducing the risk of use error due to ergonomic features of the device or
the environment in which the device is intended to be used. In order to
obtain optimum performance, the operation of the device m ust be performed
in accordance with these ‘Instructions for use’.
Note: Analytical Industries Inc. cannot warrant any damage resulting from
the misuse, unauthorized repair or improper maintenance of the device.
Prior to shipment, every device is thoroughly tested at the factory and documented in the form of a Quality Control Certif ication that is included in the
Instructions for Use supplied with every device.
For future reference in the event you need to contact the factory, we suggest
the serial number of the analyzer be recorded below:
Serial Number: ___________________________
1.1 Indications for Use
The Palm CO Carbon Monoxide Analyzer is intended to measure and display
the concentration in the range of 0 to 25 PPM of carbon monoxide in compressed breathing air tanks, intended for scuba diving. It provides continuous,
fast, reliable, and accurate carbon monoxide measurements.

2 General Safety Warnings
ALWAYS f ollow the statements below as they are essential to reducing
the risk of use error .
ALWAYS have knowledgeable personnel who have read, understand and
agree to follow the Instructions for Use operate the device.
ALWAYS retain the Instructions for Use for future reference.
ALWAYS follow Instructions for Use. Failure to do so may cause the de-
vice to fail and void the warranty.
ALWAYS inspect the device and accessories before sampling gas & ensure:
(a) there is no evidence of physical damage
(b) the sensor (particularly the sensing surface) is dry
(c) the accessories and options specified in Section 7 are present
ALWAYS follow the general calibration guidelines:
(a) use a known source of DRY carbon monoxide span gas at
least every 3 months
(b) recalibrate when the temperature or pressure of the operating
environment changes beyond ±10°C
(c) recalibrate after the battery or carbon monoxide sensor has been
replaced
ALWAYS clean the device and accessories in accordance with Section
. Failure to do so may lead to inaccurate readings, damage to the
6.1
sensor, and void warranty.
ALWAYS replace the batteries according to Section 6.2.
ALWAYS replace and install Carbon monoxide sensor according to Section
6.3.
ALWAYS contact the factory if you are in doubt while troubleshooting.
NEVER operate the device in any manner described below. Doing so
may compromise the safety of divers.
DO NOT use if reading is unstable or any malfunction is susp ected.
DO NOT use while ‘ERR’ or ‘bA’ messages are displayed on the L C D.
DO NOT use near equipment capable of emitting high levels of electro -
magnetic radiation (EMI) or radio frequency interference (RFI).
DO NOT use if device is exposed to extreme conditions, particula rly the
LCD display or sensor. Conditions include, but are not limited t o pressure, liquid submersion, heat, cold, or excessive sunlight beyond the
device’s storage temperature range for extended periods of time (refer to
Section 8).
DO NOT use outside of the parameters specified in Section 11 particu-
larly at flow rates greater than 10 liters per m inute - the backpressure
generated produces erroneously high carbon monoxide readings.
DO NOT attempt to sterilize, autoclave, l iquid sterilize, immerse in any
liquid or expose the device or accessories to steam, ethylene oxide or
radiation sterilization.
DO NOT open the main compartment of the device, except to change the
integral carbon monoxide sensor or batteries.
DO NOT open the carbon monoxide sensor or pr obe the sensing surface,
refer to Section 10 in the event the sensor should leak and someone
comes in contact with electrolyte.
DO NOT allow the device or carbon monoxide sensor to be serviced,
repaired or altered by anyone except knowledgeable personnel that are
familiar with the product's Instructions for Use
DO NOT use another manufacturer’s sensor inside this analyzer: The
design of the electronics is intended for onl y the A naly tical Ind u stri es Inc.
OSV-22-AF carbon monoxide sensors. Use of a different carb on monoxide
sensor may result in an erroneous carbon monoxide reading.

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.
