KSB Leakage Sensor
1984.8/02-EN
5.5 Display functions during operation
5.5.1 Display
The display of the analysing unit indicates the status of the leakage sensor with light
signals (LEDs).

incorrect position
5.5.2 Analog output
The analog output supplies a 4-20mA signal, indicating the averaged leakage rate
depending on the sensitivity level set via the DIP switches (ðSection5.4.4,Page19)
as per the following table.
