L5CW174TX-0RAIN GAUGE TRANSMITTER

Personal Weather Station with Wireless Sensors for Temperature & Humidity/Wind Speed/Rain Model # 47009 Thank you for purchasing this Celestron personal weather station. Please read the instructions prior to using it and we hope you will have many years of pleasure with it. Insert the base to the bottom of the Receiver by pushing it in until it clicks. The correct position is shown in the images below. If you are going to mount the Receiver on a wall (or other level surface), remove the base after set up and see the “Placement” on the last page. You will need the following tools and supplies to mount the Anemometer and Rain Gauges --- small Phillips screwdriver, hex key – 5mm (3/16”), drill, level, pencil and mast. Set Up Power for the Receiver Open the battery compartment door on the rear of the Receiver (located in top center of image on the left). Then insert six AA batteries (user supplied) with polarity as indicated in the battery compartment (see image on the right). After installation, put the battery compartment door back on. For optimum performance, please place the Receiver away from metal and other sources of interference such as mobile phones, TVs, computers, appliances, etc. If the Receiver stops showing the display or dims, replace the batteries. ENGLISH 2 Set Up the Power, Installation & Make Settings for the Anemometer (Wind Gauge) and Wireless Remote Sensor Installation/Mounting--the first step is to select the location for the Anemometer that is outdoor and not blocked on the top or sides so wind can freely reach it. The distance can be from 328ft (100m) to the Receiver or closer in an open area (the closer the better for transmission reception). The best location is usually on a mast on a roof or other high open position. The Wireless Sensor is built into the Anemometer. Before mounting the Anemometer it is best to perform a transmission test where you install the batteries (new ones) in the Anemometer (see section below) to make sure all is ok and save a lot of time if you have to relocate the Anemometer. Place the Anemometer horizontally in your selected outdoor location and install the batteries. Press and hold the “CHANNEL/SEARCH” button for a few seconds and you will see wind direction, temperature, and humidity icons flash on the display as the Receiver is now searching for remote sensors. If the readings for the outdoor information are shown within ten minutes, the transmission is successful and you can go ahead with the mounting. If the readings are not shown after ten minutes, then relocate the place you want to mount the Anemometer closer to the Receiver and remove the batteries and try the procedure again. Remove the batteries from the Anemometer prior to mounting and calibration. Remove the four small screws (shown in above image) from the door of the Anemometer with a small screwdriver. Insert two AA batteries (user supplied) as indicated in the sensor (see right image above). Replace the door of the Anemometer by installing the four small screws to hold it in place. To mount the Anemometer, you need a mast (user supplied) about 1 to 1.25” (2.54 to 3.1cm) in diameter and hardware to mount permanently in the location where you want to mount the Anemometer – see drawing below. Note that if you have an existing mast for mounting an antenna or similar device, you can mount the Anemometer on it. You should mount and ground a mast as directed in the instructions provided with the mast. If you do not have a mast, you can purchase them at aerial or antenna suppliers. Place the U-shaped metal plates around the mast. Insert the four hex screws through the holes of the U-shaped plates and the holes on the Anemometer mounting bracket. The wind vane is to be above the metal bar of the Anemometer when it is in the horizontal position per the diagram below. Tighten the hex nut onto the hex screws. MAST NORTH MAST 3 Calibrating & Installing the Batteries of the Anemometer After mounting the Anemometer, you need to calibrate the wind direction so that the Anemometer properly measures the wind direction and transmits this information to the Receiver. Be sure the batteries have been removed from the Anemometer before the calibration. You will have to recalibrate the Anemometer whenever you replace the batteries. Use the compass on the Anemometer and turn the wind vane so it is pointing due north (see drawing). Hold the wind vane pointing due north and install the batteries. The red LED above the battery door will flash a few times right after battery installation. Be sure the vane is pointing due north at the moment when the red LED flashes and then the calibration is completed. Replace the battery door. Press and hold the “CHANNEL/SEARCH” button a few seconds and the Channel 1 readings will appear within 10 minutes if the wireless sensor transmission is successful. Set Up the Power and Installation of the Rain Gauge Choose a mounting location for the Rain Gauge that is a flat and level surface 164ft (50m) or closer in an open area from the Receiver where data can be transmitted easily. The Rain Gauge should not be blocked on the top or sides so that rain can freely reach the gauge (do not put under an overhang or too close to a building or fence). Also, do not mount too close to the ground or to trees or plants. To install the batteries in the Rain Gauge, turn it upside down (image below). Then, at the same time push the two clips (inside of the two large holes at the ends) inward and lift off the cover and battery compartment. Now turn the removed part upside down (image to the right) and pull out on the two clips of the battery cover. Insert two AA batteries (user supplied) per the polarity markings on the battery compartment. Then, replace the battery cover. Finally, replace the battery compartment and cover into the outer housing by aligning with the clips and then pushing down on the cover over the clips until they are secure. Push and hold the “CHANNEL/SEARCH” button …
