CAUTION
The LeakSeeka-1 LS-1 instrument is factory calibrated for methane in air. The
alarm will be set off when the gas concentration in the air approaches the
“ALARM” set point. The “ALARM” set point is adjustable by the user for any
gas concentration within the range of 0% to 40% of the lower explosive limit
(LEL). The “ALARM” response in the presence of any other gas will be
different.

GENERAL DESCRIPTION
The LeakSeeka LS-1 is an advanced state-of-the-art leak detector capable of
detecting many combustible and toxic gases.
A partial list of these gases is:
Acetone
Ammonia
Carbon Monoxide
Alcohol
Butane
Halon
Petrol
Hydrogen Sulphide
Industrial Solvents
Lacquer Thinners
Propane
Refrigerants
Natural Gas
Jet Fuel
Smoke
Methane

OPERATING INSTRUCTIONS
BASIC OPERATION
1. Turn the instrument on in a non-contaminated atmosphere by moving the
OFF/ON/ALARM slide switch to “ON” or “ALARM”.
2. The green “READY” light will always be on when the batteries have
sufficient power to run the LS1. If the ‘READY’ light flashes then the
batteries need to be replaced.
3. During warm-up it is normal but not required that the ticking sound
increases and all lights on the ‘LEVEL INDICATOR’ are ON. The
“ALARM” light may also flash for a short time.
4. The ticking rate will slowly decrease and lights on the ‘LEVEL
INDICATOR’ will go off. The time required for this could take up to several
minutes depending on the duration of time since the instrument was last
used. (Normally approximately 15 seconds).
5. Turn the “LEVEL ADJUST” until ONLY the first green light on the
‘LEVEL INDICATOR’ is ON, this will also give a slow uniform ticking
sound.
FINDING A LEAK
6. Move the sensor head along area to be checked. Lights on the ‘LEVEL
INDICATOR’ will illuminate and the tick rate will increase as a higher
concentration of gas is detected. The lights will change from green to yellow
and ultimately red.
7. If the last red light is illuminated turn the ‘LEVEL ADJUST’ so that the
lights start to go out. This resets the LS1 for the higher concentration and
allows stronger leaks to be detected.
8. Again move the sensor head until stronger concentrations of gas are found.
Reset for higher concentrations as required.
9. If the first green light on the ‘LEVEL INDICATOR’ goes out and the tick
rate reduces then you are moving away from the leak source.

ALARM INDICATION (only works with switch set to “ALARM”)
10. The Alarm is pre-set at approximately 0.5% gas (10% of L.E.L.) with the
potentiometer in the locked position. If gas at the sensing head rises above
this level then a two tone sound will be heard and the “ALARM” light will
flash. This indicates a potentially hazardous atmosphere.
11. Note: If the instrument is in an area where high gas concentrations are
present, the “ALARM” may not stop. The unit may still detect any higher
gas levels in a normal manner.
12. To continue searching for a leak while the unit is alarming press the
“MUTE” button or slide the switch to “ON”, this disables the alarm facility.
The ‘LEVEL INDICATOR’ and ticking sound will continue to work as
detailed in BASIC OPERATION.
13. The ‘LEVEL INDICATOR’ and tick rate are independent of the alarm,
which is calibrated to the appropriate gas concentration.
SETTING THE ALARM
14. Turn on to “ALARM” for ten minutes to warm up.
15. Insert the sensor into a clean, closed container filled with the level of gas to
be detected (i.e. in the factory we set to 0.5% dry methane-air). This gas can
be in the range 0-2% methane in air or an equivalent desired gas i.e.
propane.
16. Rotate the “ALARM SET” adjustment until the “ALARM” light JUST
comes on.
17. Remove the sensor from the gas for 1 minute the re-insert to verify the
adjustment.
If the unit cannot be calibrated using this procedure, it should be returned to Kane
International or an authorised distributor for repair.

HINTS AND TIPS
18. The earphone can be plugged into the unit if there is high background noise
or the operator does not want to disturb other people. Inserting the earphone
disables the speaker.
19. If the lights do not light or go out and the audio does not work, this is an
indication that the batteries need replacing.
20. The unit will respond to some leak finding solutions (soap). Use your
LeakSeeka LS-1 first!
21. If the sensor is overexposed to some gases, the unit may take an extended
period of time to return to a steady condition.
22. To increase battery life, turn the unit “OFF” when not in use.

BATTERIES
Battery Replacement
If the ‘READY’ light fails to light or flashes the batteries need replacing.
Remove the battery cover on the back of the instrument by pressing in the catch.
Replace the batteries with 4 AA-size alkaline batteries.
Note: When replacing batteries observe polarity markings in the battery
compartment. A fresh set of alkaline batteries should operate the unit for
approximately 8 hours.
Battery Disposal
Always dispose of depleted batteries using approved disposal methods that
protect the environment
