• Intelligent tip, with environment sensing
• Flexible 15.5 inch probe length
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.
DEFINITION OF DISPLAY LEGENDS
• BATTERY SYMBOL:
• HR:
• LR:
• INT/WT:
• CA:
• READY:
KEYPAD FUNCTIONS
• ON/OFF: Turns the unit ON and OFF in a push on and push off sequence.
• 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
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)
BATTERY PRESERVATION FEATURE
An automatic timer shuts off the unit after 3 minutes of inactivity. The timer is reset whenever the
unit alarms or when any key is depressed.
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 refrigerants that are difficult to detect. (R1234yf & R407C)
3. If LED #4 is ON, the unit is in the Low Range setting which enables the
unit to detect easy to detect refrigerants. (R134a, R410A, etc.)
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
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 refrigerant gas, such as R1234yf.
The Low Range (LR) should be selected for the detection of easy to
detect refrigerants, such as R134a.
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.
