FURTHER INFORMATION
The SKYWATCH WWS transducer is sensitive to magnetic fields. This enables it to detect the small magnetic pulses sent by the
magnet on the axis of the impeller, process them electronically and display the results on the LCD. Because of this sensitivity,
SKYWATCH WWS may display values when it is near a magnetic field (coming, for example, from an electric motor, a computer or
electric lighting). There is no cause for concern; this does not at all affect the normal operation of the instrument.
WARRANTY
Starting on the date of purchase your SKYWATCH® WWS is guaranteed by JDC ELECTRONIC SA for one year in respect of all

incorrect use. JDC ELECTRONIC SA cannot be held responsible in any case for any consequences, direct or indirect, nor for any
damage that may result from the use of this instrument or from any fault or breakdown in it.
