be verified by resetting the unit
in fresh air by moving away
from source and back again.
6.3 Relative leak size
indication
The leak size indicator (rings)
remains off normally but once a
leak is detected, a number of rings
will be displayed. The number will
continue to increase or decrease
depending on the amount or con-
centration of refrigerant sensed.
The Leak Size Display is a relative
size indicator; i.e. 2 rings indicates
a larger concentration than 1 ring,
3 rings a larger concentration than
2, etc.
Because the CS LD 1.0 is a broad-
band detector, intended for use on
a very wide range of compounds,
it is not to be considered as a
measurement device. The sensiti-
vity to different compounds varies,
therefore the rings cannot reliably
be used to indicate a specific con-
centration or leak size.

To silence or mute the audio beep
and alarm signal, press the Audio
ON/OFF button (See Fig 8a). The

an alarm, a "bell" icon (Fig 8c) will
be displayed along with the relative
leak size indicator. To restore the
audio sound, press the Audio ON/

To enter the Leak Tracing Mode,
press the Graph button Item 7, Fig
1.1. This mode allows the user to
pinpoint hard to find small leaks.
The display "cursor" will move
from left to right tracking the sen-
sor output. The graph's horizontal
axis (x-axis) represents a timeline
from 0 to 8 seconds; the verti-
cal axis (y-axis) indicates signal
change intensity.
When no refrigerant is sensed, the
baseline trace will be flat. While
searching, if refrigerant is sensed,
