Filters
Charcoal Filter (Black)
A black charcoal filter is placed into a recess in the sensor gasket over the CO sensor. The
charcoal filter disk scrubs H
2
S and certain hydrocarbons out of the sample to avoid false CO
readings. If false or elevated CO readings are noticed, especially in the presence of H
2
S,
change the charcoal filter.
Hydrophobic Filter
The white, circular hydrophobic filter fits into a recessed area in the front case and is held in
place by the sensor gasket. It prevents water and particulates from entering the instrument.
Infrared Communications Port
An infrared (IR) communications port is located at the top of the instrument, near the LED.
Logged data transmits through the port in standard IrDA protocol. A computer’s infrared port
or an IrDA/USB cable connected to a USB port can be used to download data to the 04 Series
Datalogging Program. See the 04 Series Datalogging Program operator’s manual for data
logging and downloading instructions.
Batteries
2 AAA batteries (alkaline or Ni-MH) power the CO-04C. At 25°C alkaline batteries will last
at least 6,200 hours (258 days) and Ni-MH batteries will last at least 4,200 hours (175 days).
The battery icon in the upper right of the LCD shows remaining battery life.
A low battery warning activates when the CO-04C detects a low battery voltage. The CO-04C
sounds a dead battery alarm when battery voltage is too low for Measuring Mode.
WARNING:
Use only Duracell MN2400 or PC2400 or Eneloop BK-4MCC batteries to
maintain the QPS classification of the CO-04C. Use of other batteries will
void the QPS classification and may void the warranty. Do not mix old/new
or different types of batteries.
AVERTISSEMENT:Utiliser uniquement des piles Duracell MN 2400 ou PC 2400 ou
Eneloop BK-4MCC de maintenir la classification QPS de la CO-04C.
L’utilisation d’autres piles annule la classification QPS et peut annuler la
garantie. Ne mélangez pas les anciennes/nouvelles ou différents types de
piles.
WARNING:
To prevent ignition of a hazardous atmosphere, the batteries must only be
changed in an area known to be nonhazardous.
AVERTISSEMENT:Pour éviter l'inflammation d'une atmosphère dangereuse, la batterie
ne doit être remplacée que dans une zone non dangereuse.
