2 General Safety Warnings
ALWAYS follow 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
6.1
.
Failure to do so may lead to inaccurate readings, damage to the
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.
3
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 suspected.
DO NOT use while ‘ERR’ or ‘bA’ messages are displayed on the LCD.
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, particularly the
LCD display or sensor. Conditions include, but are not limited to pres-
sure, 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 minute - the backpressure
generated produces erroneously high carbon monoxide readings.
DO NOT attempt to sterilize, autoclave, liquid 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 probe 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 only the Analytical Industries Inc.
OSV-22-AF carbon monoxide sensors. Use of a different carbon monoxide
sensor may result in an erroneous carbon monoxide reading.
