PRODUKTÜBERSICHT
You have purchased an intelligent combustible gas leak detector model 55975. At the heart of
this leak detector is a new low power metal oxide gas sensor with superior performance prop-
erties such as lower current consumption and sensor longevity. The new sensor is characterized
by high sensitivity and a fast response in detecting the presence of extremely small levels of
chlorofluorocarbon gases. For this reason, this sensor was selected and integrated into the
55975 Leak Detector.
A powerful microprocessor automatically selects the best operating condition for the sensor to
ensure optimum performance throughout the life of the product. Upon turn on, the unit momen-
tarily displays the option(s) that were in use when the unit was turned off. This information is
displayed by one or more of the six (6) LEDS. Following this, the sensor is prepared for readiness
in a warm up sequence that lasts a minute or less. The warm up sequence is displayed by six
green vertical LEDs that are extinguished sequentially down until only one green (READY) LED is
lighted. This indicates the end of the warm-up sequence is reached and the unit is ready for use.
The color of the LED indicators indicate the sensitivity range that is selected by the user; green is
for the least sensitive level, yellow for medium sensitivity level and red is for the most sensitive
level. The default sensitivity level of the unit is GREEN upon initial turn-on.
Additional features are detailed and discussed in more detail in this manual.

"Super Sensitive Function" allows the unit further sensitizing beyond the standard settings for
locating small leaks
Prüfspitze:
• Intelligente Spitze mit Element zur Umgebungserfassung, um die Möglichkeit falscher Alarme
zu eliminieren.
• Flexibler 15.5 Zoll (39.3 cm) Prüfspitzenlänge, zum Erreichen schwieriger Bereiche.
Display Properties
• Status Indicators: Three (3) vertical LED indicators display the condition
and state of the unit immediately after the unit is turned ON. Status
display duration is approximately 3 seconds.
• LED #6: Identifies a LOW BATTERY condition
• LED #5: Identifies HIGH RANGE (HR) setting is enabled
• LED #4: Identifies LOW RANGE (LR) setting is enabled
• Warm-Up Status: Initially, all (6) vertical LED indicators are ON during the
warm-up stage and gradually sequence down to one GREEN LED. The
warm-up sequence takes less than 1 minute.

TASTATURSTEUERUNGEN:
• ON/OFF-Knopf (ein-/ausschalten)
• PEAK/HR/LR: The PEAK/HR/LR key serves a dual purpose:
(1) To assist the user in locating the "largest leak" in a system with
multiple leaks present.
(2) To enable the user to switch between HR (high range) and LR (low
range) modes.
• VOLUME/MUTE: The VOLUME/MUTE key sequentially selects the audible "beep" level for the
unit. The choices are: normal, low or mute. All alarms are heard at the maximum level, even in

The battery symbol LED #6 is illuminated when the battery reaches a
near end of life condition
The High Range (HR) should be selected for the detection of hard to
detect gases
The Low Range (LR) should be selected for the detection of easy to
detect gases
Conditions such as excessive air turbulence, or the accidental touching
of the probe or by blowing one's breath at the probe, trigger the
interference (INT/WT) detector
The Contaminated Atmosphere (CA) LED will turn on when the
presence of contamination is detected for a period of time.
Indicates that the unit is ready for use.
