Rain Sensor
For best results, the rain sensor should be securely mounted onto a horizontal surface
about 1 meter above the ground and in an open area away from trees or other
coverings where rainfall may be reduced causing inaccurate readings.
When securing into place, check that rain excess will not collect and store at the base
of the unit but can flow out between the base and the mounting surface (test by
pouring clean water).
After mounting the rain sensor, connect the cable to the thermo-hygro sensor at the
corresponding socket so power supply can be received and data be transmitted to the
base center
The rain sensor is now operable. For testing purposes, very slowly pour a small
amount of clean water into the rain sensor funnel. The water will act as rainfall and will
be received and displayed at the base center after about 2 minutes delay i.e. when
the reading interval is reached.

CARE AND MAINTENANCE:
x
Extreme temperatures, vibration and shock should be avoided as these may
cause damage to the units and give inaccurate forecasts and readings.
x
When cleaning the display and casings, use a soft damp cloth only. Do not use
solvents or scouring agents as they may mark the LCD and casings.
x
Do not submerge the units in water.
x
Immediately remove all low powered batteries to avoid leakage and damage.
Replace only with new batteries of the recommended type.
x
Do make any repair attempts to the units. Return it to their original point of
purchase for repair by a qualified engineer. Opening and tampering with the
units may invalidate their guarantee.
x
Do not expose the units to extreme and sudden temperature changes, this may
lead to rapid changes in forecasts and readings and thereby reduce their
accuracy.
