4. NORMAL START UP SEQUENCE
4.1 Every Time You Use The Analyser
BEFORE SWITCH-ON CHECK THAT:
the particle filter is not dirty
the water trap and probe line are empty of water
all hose connections, etc, are properly made
the probe is sampling CLEAN AMBIENT air
the water trap is correctly fitted and the instrument upright
the flue temperature is connected
Switch ON the instrument by pressing
4.2 Automatic Calibration
During this sequence the analyser pumps fresh air into the sensors to allow toxic
sensors (if fitted) to be set to zero and the Oxygen sensor to be set to 20.9 %.
After switch-on the analyser will briefly display header information :-
Kane International
(44)-1707-375550
And then show the countdown screen :-
ZERO CAL
Time : 180
FRESH AIR PURGE
The calibration time will count down in seconds to zero. Calibration time may be
changed from 2 to 6 minutes. See Set-Up menu section 5.2.5.
Note ! Three minutes is recommended to allow the sensors to stabilise fully. Anything
less than this may result in drift of the toxic and oxygen sensors in clean
ambient air.
To obtain the quoted specification an instrument should be calibrated with clean
ambient air at standard temperature and pressure (STP).
