Just Better LD-5000 Prowler Leak Detector - Manual (Page 4)

The digital leak size indicating LCD graph display remains off normally but
once a leak is detected, a number of indicating bars (up to 10 bars with
increasing height) will be displayed for all HFC and HCFC refrigerants
regardless of the sensitivity setting. NOTE: The LCD display angle can
be adjusted for ease of viewing when referring to the display for leak size.
The display may be adjusted from normal viewing (closed position) to a
30 degree angle if required. The backlight may be turned on for low light
conditions.
The graph will continue to increase or decrease depending on the amount
of refrigerant sensed. The maximum value will be displayed once the leak
source has been located. This table can be used to approximate the size
of leak:
LEAK SIZE INDICATOR
# OF BARS SIZE OF LEAK

1-3 bars
4-6 bars
7-10 bars < 0.1
0.1 to 0.5
> 0.5
To silence or mute the audio beep and alarm signal, press the MUTE but-
ton. To restore the audio sound, press the MUTE button again. (NOTE:
A few seconds is required to restore sound if the mute button is pressed
in rapid succession.)
Vibrating handle mode is always on. In noisy environments or if the audio
alarm is muted the vibrating alarm provides leak detection without having
to view the display.

The Leak Detector will default to the MED sensitivity level automatically
