Operations Operations and Quick Start Battery Cover Battery Compartment Open the battery compartment on the backside of the rain monitor as shown above Please insert two 1 5 V batteries of the type AAA ICE LR3 into the battery compartment in the right polarity After inserting the batteries the following procedures on the LCD rain monitor can be observed For testing purposes all segments of the LCD will be illuminated for 3 seconds After this on the first row the factory pre set rain factor value 267 of the will be displayed for approx 3 seconds Now the minute digits of the time display will start blinking After this close the battery compartment Important notice for an efficient commissioning For an efficient commissioning of the system it is recommended to follow the programming of the rain monitor at this step according to the items 6 2 1 1 to 6 2 1 5 of the operator manual It is recommended to proceed after finishing this programming with item 3 of this basic setting mw Batter Shes y e Compartment fal fal Open the battery compartment in the lower part of the rain gauge with a coin or an appropriate tool Insert two 1 5 V batteries of the type AAA ICE LR3 into the battery compartment checking the polarity and close it Hold the body of the rain gauge unlock the lower part by turning it agai2. Please only use new batteries of the correct type Avoid that the batteries will be disconnected from the contacts during commissioning This could cause start up and transmission problems and may require a new initial setting procedure 5 2 New setting calibration Should a new calibration of the system be required for reasons whatsoever please proceed as follows 1 Take out the batteries from both the rain monitor and the rain gauge 2 Wait for at least 30 seconds to avoid start up and transmission problems 3 Repeat the procedures as per 5 1 Initial Setting Note Please note that during a new setting calibration both parts need to be adjusted as new 6 Button functions The rain monitor has only two controls the RAIN SET and HISTORY buttons The functions of each button are described below 6 1 Display Mode 6 1 1 TIME DATE and RAINFALL When the RAIN SET button is pressed the following functions are displayed in sequence in the upper section of the LCD screen before starting from the beginning TIME DATE TOTAL rainfall since the rain monitor was started Amount of rain during the last hour 1H Amount of rain during the last 24 hours 24H Amount of rain since the beginning of the last rainfall small rain symbol 6 1 2 HISTORY 6 1 2 1 Bar Chart When the HISTORY button is pressed the following bar chart graphics are displayed in the upper section of the LCD screen before starting from the beginning
