WARNING
Before each day’s usage sensitivity must be tested on a known concentration of the
gas to be detected equivalent to 25 – 50% of full scale concentration. Accuracy
must be within 0 to +20% of actual. Accuracy may be corrected by calibration.
The Catalytic Flammable Sensors sensitivity can be adversely affected by exposure
to certain substances (silicon and sulphur compounds are examples). Every effort
should be made to avoid exposure to these substances. Following an H
2
S alarm or
repeated gassing with H
2
S a check should be performed on the Catalytic Flammable
sensor to verify its accuracy and a calibration performed if necessary.
By default, no alarms are provided for the 0-100%/Volume Flammable IR sensor.
The user can set up alarm levels via the ICU software.
Hydrogen (H
2
) cannot be detected using the IR principle.
If -0.0% v/v for the electrochemical CO
2
sensor channel is permanently displayed,
a sensor zero calibration needs to be performed in clean air. The alarm level A1
for the electrochemical CO
2
range must not exceed 0.5% v/v.
Do not calibrate the electrochemical CO
2
channel if CO
2
is indicated in clean
air after the apparatus has been exposed to CO
2
concentrations above the upper
limit of the measuring range. In this case leave instrument in clean air overnight
before calibration.
The calibration interval for the electrochemical CO
2
sensor shall not exceed 1
month.
Dispose of the spent cartridge and its packaging in accordance with local
regulations.Donotdisposeofinre.
