General information
The ITE-XTRA is the culmination of over 30 years of Leak detector manufacturing
experience. ITE is proud to present this tool as the most stable and sensitive negative
corona leak detector ever made. We have incorporated all of our experience, and years
of customer feedback into this product, in the hope of providing our valued customers
with the best of everything; price, performance and reliability.
An advanced microprocessor is the heart of this unit. Its digital signal processing
permits better management of the circuitry and sensing tip signal than ever before
possible. Additionally, the number of components used in the circuit is reduced nearly 40
%, increasing reliability and performance. The microprocessor monitors the sensing tip
and battery voltage levels 4000 times per second, compensating for even the most minor
fluctuations in signal. This translates into a stable and dependable tool in almost any
environment.
Convenience features have been added to enhance the usability of the ITE-XTRA. Seven
levels of sensitivity provide an increase of 64 times from level 1 to level 7. Unique Tri-
color led‟s show a progressive and wide ranging leak size indications, communicate the
sensitivity level, and provide a true voltage indication of battery power level. A tactile
keypad controls all functions of operation. A revolutionary new case design gives the
user grip and control, and places the visual indicators in direct sight during use.
Please take a few moments to read through the following pages, in order to understand
and benefit from all the capabilities of your new ITE-XTRA. We trust that you will be
100 % satisfied with your new purchase. If you have any questions or comments after

Operating features
Power indication / battery test
The ITE-XTRA provides two indications of battery voltage status; a constant power
indicator (almost LED) and a battery test function.
The constant power indicator allows the user to see the battery level at all times. The
LED will remain on whenever the unit is powered on. It may appear as one of three colors
(See Fig. 3).
GREEN Battery voltage is normal, sufficient for proper operation.
ORANGE Battery voltage is approaching the lower threshold for operation, replace
as soon as possible.
RED Battery voltage is below acceptable operating level.
Battery Test Function.
This feature is activated by pressing the Battery Test key.

When pressed, the LED‟s will display a three color bar graph indication of true battery
voltage (See Fig. 4). The LED‟s correspond to voltage as shown in the figure.
Not all LED's will always be on; the number of LED‟s on, indicate the voltage level.
The battery voltage display will remain as long as the BATTERY TEST key is depressed.
Release the BATTERY TEST key to return to normal operation. This function may be
activated at any time during operation, and does not interrupt alarm signals.
Automatic Circuit/Reset Feature
The ITE-XTRA features an Automatic circuit and a Reset function key that set the unit
to ignore ambient concentrations of refrigerant.
AUTOMATIC CIRCUIT –Upon initial power on, the unit automatically sets itself to
ignore the level of refrigerant present at the tip. Only a level, or concentration,
greater than this will cause an alarm. CAUTION: Be aware that this feature will cause
the unit to ignore any refrigerant present at turn on. In other words, with the unit
off, if you place the tip up to a known leak and switch the unit on, no leak will be
indicated!
RESET FEATURE –Pressing the RESET key during operation performs a similar
function. When the RESET key is pressed it programs the circuit to ignore the level
of refrigerant present at the tip. This allows the user to „home-in‟ on the source of
the leak (higher concentration). Similarly, the unit can be moved to fresh air and
reset for maximum sensitivity. Resetting the unit with no refrigerant present (fresh
air) causes any level above zero to be detected. Whenever the unit is reset, the LED‟s
(except the leftmost power indicator) will turn Orange for 1 second. This provides a
visual confirmation of the reset action.
Sensitivity Adjustment

The ITE-XTRA provides seven levels of sensitivity. The sensitivity level is indicated on
the visual display when either the SENSITIVITY OR SENSITIVITY keys are
pressed. The base beeping tone is also an indication of sensitivity level.
When the unit is switched on, it is set to sensitivity level 5.
1. To adjust the sensitivity, press the SENSITIVITY or SENSITIVITY key. When
the key is pressed, the visual display will show the LED‟s red. The number of LED‟s lit,
indicates the level (See Fig. 5). Level one (lowest sensitivity) is shown by the leftmost
LED. Counting from left, levels 2 through 7 are indicated by the corresponding
number of red LED‟s: i.e. level 7 is shown by all LED‟s lit.
2. Pressing the SENSITIVITY or SENSITIVITY key will change the sensitivity.
The keys can be pressed intermittently to change levels one at a time, or held down
to move quickly through the levels.
3. Each time the level is increased (or decreased) the relative sensitivity is doubled (or
halved). In other words, level 2 is twice as sensitive as level 1, level 3,4 times as
sensitive, etc… This allows sensitivity to be increased as much as 64 times!

Alarm Indications
The ITE-XTRA features 18 alarm levels. This permits a clear indication of relative leak
size and strength. The progressive indicators can be used to home-in on a leak; as the
increasing alarm levels indicate that the source (highest concentration) is being
approached. Each level is indicated by additional LED‟s in one of three colors, Green,
Orange or Red (See Fig.6).
At first the display will light Green, from left to right. Then, the LED‟s will light Orange,
from left to right, replacing the Green one at a time. Finally, the LED‟s will light Red,
from left to right, replacing the Orange, one at a time.
Operating Instructions
Operation
1. Switch the unit on by pressing the ON/OFF key. The display will illuminate with the
reset indication (Left LED green, all others Orange) for 2 seconds.
2. Verify the battery level by observing the constant power indicator (see above).
3. Upon turn on, the unit is set to sensitivity level 5. A rapid, but steady beep rate will
be heard. If desired, the sensitivity can be adjusted by pressing the SENSITIVITY
or SENSITIVITY key, as described above.
4. Begin searching for leaks. When refrigerant is detected, the audible tone will change
to a „siren‟ type sound, distinctly different from the base beep rate. Additionally, the
visual indicators will light progressively as described in the Alarm Indications section.
5. Sensitivity can be adjusted at any time during operation by using the SENSITIVITY
or SENSITIVITY key. This adjustment will not interrupt detection.

Operating tips
The following section includes several general operating tips, and the SAEJ1628
recommended procedure for leak detection.
1. Adjust the sensitivity up, only when a leak cannot be found. Adjust the sensitivity down
only when resetting the unit does not allow you to „home in‟ on the leak.
2. In areas that are heavily contaminated with gas, the unit may be reset to block out
ambient concentrations of gas. The probe should not be moved while the unit is being
reset. The unit can be reset as many times as needed.
3. In windy areas, even a large leak can be difficult to find. Under these conditions, it is
best to shield the potential leak area.
4. Be aware that the detector may alarm if the sensing tip comes in contact with
moisture and/or solvents. Therefore, avoid contact with these when leak checking.
SAE J1628 Recommended Procedure
NOTE: On Automotive A/C Systems leak test with the engine not in operation.
1. The air conditioning or refrigeration system should be charged with sufficient
refrigerant to have a gauge pressure of at least 340 kPa (50 psi) when not in
operation. At temperatures below 15°C (59 °F), leaks may not be measurable, since
this pressure may not be reached.
2. Take care not to contaminate the detector probe tip if the part being tested is
contaminated. If the part is particularly dirty, or condensate (moisture) is present, it
should be wiped off with a dry shop towel or blown off with shop air. No cleaners or
solvents should be used, since the detector may be sensitive to their ingredients.
3. Visually trace the entire refrigerant system, and look for signs of air conditioning
lubricant leakage, damage and corrosion on all lines, hoses, and components. Each
questionable area should be carefully checked with the detector probe, as well as all
fittings, hose to line couplings, refrigerant controls, service ports with caps in place,
brazed or welded areas, and areas around attachment points and hold-downs on lines
and components.
4. Always follow the refrigerant system around in a continuous path so that no areas of
potential leaks are missed. If a leak is found, always continue to test the remainder
of the system.
5. At each area checked, the probe should be moved around the location, at a rate no
more than 25 to 50 mm/second (1-2 in/second), and no more than 5 mm (1/4 in) from
the surface, completely around the position. Slower and closer movement of the
probe greatly improves the likelihood of finding a leak (see fig.7). Any increase in
beep rate is indicative of a leak.

6. An apparent leak shall be verified at least once as follows:
a. Blow shop air into the area of the suspected leak, if necessary, and repeat the
check of the area. In cases of very large leaks, blowing out the area with shop
air often helps locate the exact position of the leak.
b. First move the probe to fresh air and reset. Then hold the probe tip as close as
possible to the indicated leak source and slowly move around it until the leak is
confirmed.
Automotive A/C Systems only-
7. Leak testing of the evaporator core while in the air conditioning module shall be
accomplished by turning the air conditioning blower on high for a period of 15 seconds
minimum, shutting it off, then waiting for the refrigerant to accumulate in the case
for 10 minutes.
After such time, insert the leak detector probe into the blower resistor block or
condensate drain hole, if no water is present, or into the closest opening in the
heating/ventilation/air conditioning case to the evaporator, such as the heater duct or a
vent duct. If the detector alarms, a leak apparently has been found.
All Systems-
8. Following any service to the refrigerant system and any other service which disturbs
the refrigerant system, a leak test of the repair and of the service ports of the
refrigerant system should be done.

Maintenance
Proper maintenance of you Leak Detector is very important. Carefully following the
instructions, outlined below, will reduce performance problems and increase the live
expectancy of the unit.
WARNING: TURN UNIT OFF BEFORE REPLACING THE SENSING TIP. FAILURE TO DO
SO MAY RESULT IN A MILD ELECTRICAL SHOCK!
Keep the sensing tip clean: Prevent dust, moisture and grease build-up by utilizing the
provided tip protector. Never use the unit without the protector in place.
Before using the unit always inspect the tip and protector to see that they are free of
dirt and/or grease. To clean:
1. Remove protector by grasping and pulling off tip.
2. Clean protector with shop towel and/or compressed air.
3. If the tip itself is dirty it can be cleaned by immersing in a mild solvent, such as
alcohol, for a few seconds, and then using compressed air and/or a shop towel to clean.
NOTE: Never use solvents such as gasoline, turpentine, mineral spirits, etc… as these will
leave a detectable residue and desensitize your unit.
Sensing tip replacement
The tip will eventually wear out and require replacement. It is difficult to predict exactly
when this will occur since tip longevity is directly related to the conditions and frequency
of use. The tip should be replaced whenever the alarm sounds or becomes erratic, in a
clean, pure, air environment.
To replace the tip:
1. Make sure the unit is OFF.
2. Remove the old tip by unscrewing counter-clockwise.
3. Use the supplied replacement tip, located in the carrying case. Replace by screwing on
clockwise.
