SC-04
Replacing the Batteries (Alkaline or Ni-MH)
WARNING:
To prevent ignition of a hazardous atmosphere, 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.
WARNING:
Use only Duracell MN2400 or PC2400 or Eneloop BK-4MCC batteries to
maintain the QPS classification of the SC-04. 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 SC-04.
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.
Replace the batteries when the last bar in the battery icon is flashing.
1. Make sure the SC-04 is off.
• Calibration fails.
• The calibration value does not
match the cylinder gas
concentration.
• The sample gas is not reaching
the sensor because of a bad
connection.
• The calibration cylinder is out
of gas or is outdated.
• The sensor needs replacement.
1. Make sure the SC-04 has been properly
set up for calibration.
2. Check all calibration tubing for leaks or
for any bad connections.
3. Verify that the calibration cylinder
contains an adequate supply of fresh test
sample.
4. If the fail condition continues, replace
the sensor.
5. If the difficulties continue, contact RKI
Instruments, Inc. for further instruction.
