OPERATING FEATURES

Automatic Circuit/Reset Feature

The  TSCE-J1  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 ignore any gas concentration when the unit is powered on. In other words, under the condition 

that the unit is turned 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 sauce of the leak (higher concentration).Similarly,the unit can be moved to fresh air and Meet 

for maximum sensitivity.Resetting the unit with no refrigerant present (fresh air )causes any level above zero to 

be detected,Wheneveräre unit is reset, the LEDs(except the leftmost power indicator) will turn red for 2 seconds.

This provides a visual confirmation of the reset action.

Sensitivity Adjustment

The TSCE-J1 provides seven levels of sensitivity.the sensitivity level is indicated on the visual display when either 

the SENSITVITY ↑ 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 LEDs red. The number of LEDs lit , indicates _ level 

(See Fig.4). level one (lowest sensitivity)is shown by the leftmost LED. Counting from left, levels 2 through 7 are 

indicated by the corre-

sponding number of red LEDs; i.e. level 7 is shown by all LEDs 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 TSCE-J1 features 18 alarm levels. This permits a clear indi- cation 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 LEDs in one of three 

colors ,Red,Green or Orange (See Fig 5).

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 Red)for 3 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.lf desired,the 

sensitivity can be adjusted by pressing the SENSITIVITY 

4. Begin searching for  Ieaks.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 SENSITIV ITY or SENSITIVITY key. This 

adjustment will not interrupt detection.

6. If a full alarm occurs before the leak is pinpointed,press the RESET key to reset the circuit to a zero reference as 

described above. 

OPERATING TIPS  

The following section includes several general operating tips,and the Delicacy recommended procedure for leak 

detection. 

1. Adjust the sensitivity up ,only when a leak canit 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 ot 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.

OPERATING FEATURES

HI300  TSCE-J1 Recommended Procedure

NOTE:On Automotive NC 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 contaminaled.if the part is 

particularly dirty, or condensate(moisture)is present, it should be wiped off with a dry shop tower or blown off 

with shop air .No cleaners or solvents should be used, since the detector maybe 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, hoses 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 50mm/

second(1-2in/second). And no more than 5mm(1/4in) from the surface, completely around the position. Slower 

and closer movement of the probe greatly improves the likelihood. of finding a leak (see fig.6).  

6. An apparent leak shall be verified at least once as floolws:, a)Blow shop air into the area of the suspected leak,if 

nebessary,and repeat the check of the area.ln 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 a 

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 evaporalor 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 retrigerant 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 closet opening in the heat- ing/ventilation/air conditioning case to the evaporator,such as 

the heater duct or a vent duct.lf 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 parts of the refrigerant system should be done.

The TSCE-J1 leak Detector may also be used to: • Detect leaks in other systems and storage/recovery containers. 

It will respond toALL halogenated(contains Chlorine of Fluorine) refrigerants. This includes, but is not limited 

to: CFCs e.g.R12,R1 1 ,R500,R503 etc... e.g.R22,R123,R124,R502 etc... e.g.R134a,R404a,R125 etc... HCFCs HFCs 

Blends such as AZ-50.HP62.MP39 etc...

•  Detect Ethylene Oxide gas leaks in hospital sterilizing equipment(it will detect the halogenated carrier gas)

•  Detect SF-6 in high voltage circuit breakers • Detect  most  pases  that  contain  chlorine,Fluorine  and 

Bromine(halogen gases) 

• Detect cleaning agents used in dry cleaning applications such as perchloroethyl

APPLICATIONS

MAINTENANCE

Proper maintenance of your Leak Detector is very important. Carefully following the instructions, outlined below, 

will reduce performance problems and increase the life 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. 2.

Remove protector by grasping and pulling the tip off . 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°gas 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.
