-Insert the rain sensor in its holder. It will also automatically hold the pointer. The rain sensor cable and the magnet of the pointer must be located on the same side.

-Now place the collection funnel from the top on to the sensor-holder and lock it in by turning it to the right.

-Now reinstall the casing and lock it by turning it to the right in the sensor-holder till it locks in. Ensure that the drain-holes of the casing and the sensor-holder match (drain-hole of the casing points outwards).

7.2. Setting the rain sensor

The rain quantity measurement system has a high level of accuracy when it leaves the factory; so normally, no adjustments are required.

Adjustments would be necessary only if the accuracy requirements are very high.

Before you start calibrating the rain water measurement recorder, you need to reset to zero the rainfall quantity value that has already been totaled up (see chapter 3.2. "RESET"), total rain quantity display stands at zero). Further, the rainfall quantity for adjustments must be displayed in "inch".

Proceed as follows for exact calibration:

1.Slowly pour 3.38 fl. oz. (100 ml) water over a period of 10 minutes in the rain sensor collection funnel.

Note!

Quick pouring will give wrong measurement results! Pour the water so slowly into the funnel that there is a even passage of water and there is no water in the funnel at any point of time.

2.The displayed total quantity should now be 0.26 inch (6.5 l/m2).

3.If a different value is shown, then the calibration value that is mentioned is to be recalculated as follows:

0.26 x Current calibration value

New calibration value =

Actual value (Display reading after filling in the water)

The new calibration value must now be entered in the configuration menu (see 3.3.7., System menu/RAIN CAL).

The factory setting is 295/pointer stroke.
