BATTERY TEST
Turning the unit ON will automatically run the battery function test
and display the battery condition on the UNITS LED display. To view
the remaining battery life, press and hold the ON/OFF button.
1. SENSITIVITY LEVELS
55200 offers six sensitivity levels (1-6). The highest sensitivity will detect a 1/10 oz leak per year. Turn ON
the unit, it will default to Level 5. (Level 5 is the recommended setting to begin inspection). To view the
sensitivity level on the LED display, press either the UP or DOWN arrow. The LED display will illuminate for
approximately two seconds. (One red LED for every sensitivity level.) One illuminated red LED is the lowest
sensitivity setting and six illuminated red LEDS are the highest.
Low Sensitivity
Setting (RED)
The sensitivity level can be increased by the UP arrow and decreased by the DOWN arrow. Pressing the
selected arrow once will adjust the sensitivity to the next level. Pressing and holding the arrow will continue
to move the setting until the arrow is released.
2. DETECTION LEVELS
55200 offers 15 levels of detection. As the unit approaches the leak source and the refrigerant concentra-
tion increases, the audible alarm will increase in speed and the LED will progress through a series of three
colors, Red, Yellow and Green. The LED will display 5 levels of detection in each color range.
Low Detection
Levels (RED)
The detection level will vary depending on the level of the sensitivity setting. The same size leak will display
higher detection levels in higher sensitivity settings and lower detection levels in the lower sensitivity
settings.
3. RESET FUNCTION
The primary use for the RESET function is to pinpoint the leak source. When the unit detects a leak and goes
into full alarm, press the RESET button. Resetting will ignore any leaks at that level and only detect leaks of
higher concentration.
UV/BLUE LIGHT
The UV/Blue light can be used to help detect leaks in systems containing Ultra Violet Dye. The light can be
activated by pressing the UV Light button. This function will operate with the unit ON or OFF.

IMPORTANT LEAK DETECTION TIPS:
A. Make sure that the air conditioning/refrigeration system is turned OFF before inspection. A sufficient
amount of refrigerant must be present in the system. A minimum gauge pressure of 50 PSI at ambient
temperature of 60˚ and above with the system OFF is required for efficient leak detection.
