OPERATION CHECK

First follow steps 1, 2 and 3 (page 4) in the
Operations section. Then expose the sen­sor to a known gas source such as an unlit
butane lighter. The tick should increase
when the gas is applied. The tick will de­crease when the gas is removed.

If the unit fails to respond, the sensor may
need replacing or the unit may need to be
sent in for repair (see below).

CAUTION:

This instrument must be
only repaired by a factory authorized re­pair technician.

SENSOR REPLACEMENT

1. Turn the unit off

2. Pull off the sensor cap

3. Unplug the old sensor and discard

4. Line up reference tab on side of sensor
with reference mark ( ) on sensor
circuit board and plug in sensor

5. Replace sensor cap

6. Turn on unit and perform “Operation
Check”

OPERATIONS (cont. from page 4)

5. When this instrument is used in noisy
environments, look at the red leak indica­tor LED that flashes more rapidly as the
tick rate increases. You can also use the
supplied earphone.

6. If the green LED does not illuminate or
blinks, the batteries must be replaced.

7. If the instrument does not perform or it
has been damaged, test the instrument by
following the “operation check” procedure
in this manual.

If the green LED fails to illuminate, the bat­teries need replacement. Depress the latch
using a coin and slide the battery compart­ment cover off. Replace the batteries with
3 “C” alkaline batteries.

When replacing the batteries observe the
polarity markings on the sides of the bat­tery compartment. A fresh set of alkaline
batteries should operate the unit for approxi­mately 30 hours.

GENERAL DESCRIPTION

The SENSIT®TKX instrument is an ad­vanced state-of-the-art leak detector ca­pable of detecting many combustible, non­combustible and toxic gases.

The SENSIT®TKX solid state sensor is sen­sitive to most combustible and/or toxic
gases.
A partial list of these gases is:
Acetone, Alcohol, Ammonia, Steam, Bu­tane, Gasoline, Jet Fuel, Hydrogen Sulfide,
smoke, Industrial Solvents, Methane, Lac­quer Thinner , Naphtha, Propane, Natural
Gas.

CAUTION
This instrument is not to be used as a

carbon monoxide investigative tool or
to quantify any gas concentration.

SAFETY APPROV AL

OPERA TIONS

1. Turn the unit on in an uncontaminated
environment by moving the switch from the
“OFF” to the “ON” position.

2. The green ready LED will illuminate if
there is ample battery power. The red LED
may flicker and the tick may sound during
the warm up. To silence the tick, rotate
the tick wheel fully counterclockwise.

3. Adjust the “TICK ADJUST” by rotating it
in a clockwise direction until a uniform tick
begins to sound. A uniform tick rate indi­cates a fully warmed up instrument. The
red LED will flash at the same time the tick
sounds.

4. Approach suspected leak areas with the
sensor until the tick begins to increase.
When the tick increases do not move the
sensor from the suspected leak area, ro­tate the tick adjust slightly counterclock­wise to slow the ticking sound and con­tinue to approach the leak. Continue to

use this method to pinpoint the leak.
REMEMBER: An increase in tick indicates

you are approaching a leak, a decrease in
tick indicates you are moving away .
