2. SAFETY WARNING

This analyser extracts combustion gases that may be toxic in relatively low concentrations. These gases are exhausted from the side of the instrument. This instrument must only be used in well ventilated locations. It must only be used by trained and competent persons after due consideration of all the potential hazards.

Protection Against Electric Shock (in accordance with EN 61010-1 : 1993)

This instrument is designated as Class III equipment and should only be connected to SELV circuits. The battery charger is designated as:

Class II equipment Installation category II Pollution degree 2 Indoor use only Altitude to 2000m Ambient temperature 0°C-40°C Maximum relative humidity 80% for temperatures up to 31°C decreasing linearly to 50%RH at 40°C Mains supply fluctuations not to exceed 10% of the nominal voltage.

3. FIRST TIME USE

Charge the battery for 12 hours, following this an overnight charge should be sufficient for an average 8 hour day. See Main Parameter displays for Battery Indicator.

The KANE940 has a rechargeable lead acid battery which uses a different charger than other Kane analysers. Ensure the correct charger is used or damage may occur to the instrument.

Check that you have all the items you have ordered. Take time to read this manual fully. When using the analyser for the first time you will need to choose from:-

Language selection Calibration countdown time CO gas alarm NOx percentage for calculation Time and Date Printed header name and telephone number

The SET UP MENU (Section 5.2.5) gives details of how to change the above settings.

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).

Once the time has reached zero an audible beep will be heard and will show the selected fuel on the following display:-

NATURAL GAS

∗PRESS -MENU- KEY∗

Press

This zeros the toxic sensor and sets Oxygen to 20.9%. The next screen is the MAIN DISPLAY of the analyser:-

4.3 Main Displays

The main display can be changed to show either 4 or 8 parameters at one time. Two options are available when 4 parameters are selected.

• 4 Page Mode displays 4 lines of data in set format, each page is predefined.

• Line scroll mode allows you to customise the display to show the data you require.

• 8 Page Mode displays 8 parameters on 4 lines in set format, the bottom two can be

changed.

Changing between the different modes is detailed in Display Menu Section 5.2.4.

4.3.1 4 Page Mode
