Leak Alarm Level
The level at which an indication should be considered as a leak. The default
setting is 1.00E+01=10.
Leak Rate Unit
Min Presentation Time
The measured value is shown until the sensor has recovered. A longer time can
be set by increasing the Min Presentation Time. The default value is 1 second,
but values from 0 - 120 seconds can be used. Applies only to Analysis Mode.The
Screen Save function will dim the display lamp after a certain time of inactivity.
Leak Alarm Indications
There are four choices of leak alarm indication:
• LEDs only: This is the default setting. No other indication than red LED on
front and probe.
• Flashing Backlight: The backlight starts to flash when signal exceeds leak limit.
• Chopped audio signal: The audio signal is chopped (silent/loud) when signal
exceeds leak limit.
• Backlight & Audio: A combination of both backlight flashing and audio chop-
ping when signal exceeds leak alarm limit.
Lowest Frequency (Analysis Mode Settings)
The lowest frequency of the sound can be adjusted using Lowest Frequency,
i.e. when no gas is detected. The default value is 1 Hz but values from 0 to 10
Hz can be used. 0 Hz means that the loudspeaker is silent when the detector
has reverted to background level. The setting is not valid in Combined Mode.
