mute.
• HML (HIGH/MEDIUM/LOW SENSITIVITY): The HML key selects the sensitivity range of the unit.
The color of the LED and the tone of the "beep" change for each sensitivity selected.
(High=Red, Medium=Orange, Low=Green)
DISPLAYING THE STATUS SETTINGS
• Depress the ON/OFF key, upon initial turn-on, the unit will momentarily display the status
conditions of the unit. This information will be displayed for approximately 3 seconds. One or
more LED's will be ON during this brief time to display the following information:
1. If LED #6 is ON, the battery is reaching end-of life and should be replaced before the unit's
operation is affected.
2. If LED #5 is ON, the unit is in the High Range setting which enables the
unit to detect gases that are difficult to detect.
3. If LED #4 is ON, the unit is in the Low Range setting which enables the
unit to detect easy to detect gases.
DISPLAYING THE WARM-UP STATUS
• All six (6) LEDS turn ON and sequentially become extinguished until only one GREEN LED
remains. At this point, the audible "beep" begins (unless the unit is muted), which is an
indication that the unit is ready for use. This process takes less than 1 minute.
• The unit always defaults to LOW sensitivity upon initial turn-on, as indicated by the GREEN LED.
CHANGING THE AUDIBLE LEVEL
• The Volume/Mute key enables the user to change the audible "beep" level in a sequential
manner. Successive depression alters the audible level from Normal, Low and Mute. Upon
each depression, the unit visually displays (for less than 1 second) the selected audible level
as follows:
1. In Normal, six LED's are flashed briefly and the "beep" resumes at the maximum
audible level
2. In Low, three LED's are flashed briefly and the "beep" resumes at a lower audible level
3. In Mute, only the READY LED stays ON and the audible is muted.
4. The selected audible level will remain stored in the unit unless changed.
CHANGING THE SENSITIVITY
• Depressing the HML key alters the sensitivity of the unit sequentially in the following manner:
1. When in High Sensitivity, the LED #1 (READY) changes to RED
2. When in Medium Sensitivity, LED #1 changes to YELLOW
3. When in Low Sensitivity, LED #1 changes to GREEN
4. During the detection of a leak, all the LED'S follow the color of the READY light.
CHANGING THE OPERATING RANGE FROM HR TO LR
• After the unit has warmed up and the READY indicator is ON, press and hold down the PEAK/
HR/LR key all LED's are off. Release the key. The unit will perform a new warm-up sequence
with the new operating range.
REDUCING FALSE LEAK DETECTION
Under Adverse Conditions
To discriminate between false alarms and actual leak detection that may occur in the presence of
excessive air turbulence or accidental touching of the probe tip, the interference detector creates
a momentary interruption in the leak detector for several seconds, resulting in the following:
• When interference is detected, the audible beep stops and the INT/WT light LED #3 and the
READY LED #1 begin to flash briefly. When the unit is ready to resume operation, LED #3
extinguishes, the READY LED #1 turns ON and the audible resumes
In a Contaminated Environment
When a contaminated area is detected by the unit lasting for a duration of time during a leak
search, the sensor detects the change and will respond in the following manner:
• The READY indicator LED #1 will extinguish, the audible will stop (unless muted) and the INT/
WT indicator LED #3 will turn ON.
• The unit performs a re-calibration for the contaminated environment. When done, the CA
indicator LED #2 turns ON, the READY indicator LED #1 turns ON and the audible returns,
indicating that the unit is ready for use to detect leaks in a contaminated environment.
SCHNELLSTART-TIPPS ZUM FINDEN VON LECKAGEN
Eine plötzliche peitschenartige Bewegung der Spitze, oder ein Pusten in den Sensor, können beim
Lecksucher falsche Alarme auslösen. In das Produkt sind elektronische Sensoren integriert, um
solche Bewegungen zu erkennen und falsche Alarme zu reduzieren.
ence is detected, the LED #3 will begin to flash indicating interference then normal operation can
resume after the READY LED appears.
1. Wird mit der Lecksuche begonnen, ohne Kenntnisse über das Ausmaß der Leckage zu haben,
ist die Empfindlichkeit des Geräts auf LOW einzustellen. Die Einstellung LOW ermöglicht dem
Gerät sowohl mittelgroße, als auch große Leckagen zu erkennen.
2. Die Prüfspitze etwa 3/8 Zoll (9 mm) über dem Bereich mit den vermuteten Leckagen bewegen.
Die Prüfspitze an der Leckage vorbei bewegen, um abzuklären, ob die Leckage erkannt wurde.
Die Prüfspitze nicht an die Leckagestelle halten. Zur Überprüfung die Prüfspitze wieder zum
gleichen Bereich zurückbringen, wo die Leckage erkannt wurde.
3. Wurden mit der NIEDRIGEN (LOW) Empfindlichkeitseinstellung keine Leckagen gefunden, die
Empfindlichkeit auf MITTEL (MEDIUM) erhöhen und o.g. Schritt (2) wiederholen.
4. Zur Feststellung extrem kleiner Leckagen 0.1 oz/yr (2.8 Gramm) oder weniger, ist die
Empfindlichkeitsstufe HOCH (HIGH) zu verwenden. Aufgrund der ausgesprochen kleinen
Leckagegröße, muss die Prüfspitze so nah wie möglich an die Fläche gebracht werden (ohne
ein Objekt zu berühren). Das Berühren eines Objekts wird von den Sensoren der Prüfspitze
erkannt und führt zu einer kurzen Unterbrechung im Detektor. Bei der Prüfung auf
Leckagen in einer kontaminierten Umgebung, erfasst der Sensor die kon taminierte Umgebung
und passt sich automatisch den neuen Bedingungen an.
