TRANSMITTER BOX-BATTERY INSTALLATION

The solar panel on transmitter box is an energy saving feature, which is an

environmentally friendly way to provide power to the sensors and prolongs battery

life. It can entirely provide power to the supplied rechargeable battery. Sensors

can operate entirely on the rechargeable battery power. Locate the transmitter box

under direct sunlight for power supplying by the solar panel.

The rechargeable battery from factory is not with full

battery for long time use and it probably becomes

low battery during the shipping. We recommend

you to charge it for several hours by the connected

solar panel.

You can also purchase a power adapter separately

for directly providing power to the transmitter box.

The output voltage of the power adapter is 3V.

Route the adapter cable through the cable slot.

Please check the solar panel connection. If it is not ﬁrmly plugged, please re-connect the solar panel:

Plug the end of color-corded connector into corresponding socket in the transmitter

box as shown below and place the wires neatly inside the box.

To install the rechargeable battery:

Insert the battery into the battery compartment, matching the polarity +/-.

REMOVE SETTING

For removing the previous setting from the transmitter box, you can press RESET and KEY at a time, then only release RESET, red light ﬂashes 5 times. Then release KEY. The channel setting and calibrated wind direction are all removed

from the transmitter box.

LED LIGHT INDICATOR

There are three colors of LED lights in transmitter box, green, red and blue.

Different color combinations indicate different status.

Blue ﬂashes A normal transmission (WMR300A)

Green ﬂashes A normal transmission (WMR300)

SENSORS INSTALLATION

You have three options to install the sensors.

The transmitter box is capable of transmitting data wirelessly an approximate

operating range of 300m (1000 feet). Ideal placements for the sensor would be

in any location on the roof of a building that is in an open area away from trees

or other obstructions preventing from the wind ﬂow for an accurate reading.

Additionally, locate the transmitter box at the direct sunlight for power supplying

by the solar panel.

CHANNEL SETTING

Your weather station system can expand with up to 8

sets of thermometer & humidity sensors, and one of

each of wind and rain sensors, which share one main

unit to display the weather readings. You can number

each transmitter box with an independent channel ID (1-8) by sliding the switches.

Please follow the below chart to adjust the sliding switches of SW1:

The below 0 in the chart represents off and 1 represents on.

Make sure the temperature and humidity sensor should be located at least

1.5 meters above the ground surface to avoid the ground temperature affecting

accuracy of the temperature and humidity sensor.

Option 1: All sensors are installed on a pole.

Please take off the rain collector before installation and choose a pole with

the diameter that is about 32-45mm.

1. Locate one U-bolt without ﬂat washers, lock washers and hex nuts into the gap

of the rain gauge (Figure 1).

2. Let the pole fully approach to the inner of the U-bolt (Figure 2).

3. Locate the other U-bolt without ﬂat washers, lock washers and hex nuts into

the screw holes of the rain gauge (Figure 3).

4. Put the backing metal plate through the U-bolt and securely tighten two pairs of

the ﬂat washers, lock washers and hex nuts over the plate (Figure 4) by wrench.

5. Insert the two ends of the ﬁrst U-bolt into the screw holes of the wind sensor (Figure 5).

6. Tighten the other two pairs of ﬂat washers, lock washers and hex nuts on the

U-bolt of the wind sensor by wrench (Figure 6).

DIRECTION CALIBRATION

Before pairing a wind sensor, make sure the head of the wind vane of that sensor point to the north while pressing KEY for 2 seconds in the transmitter box to calibrate

the direction. If the calibration is successful, red light ﬂashes once. You can use a

compass to look for an accurate direction of north if necessary.

However, if you are the user in North America, there are already 15°(degree)

variations existing between the true north and a compass reading of north. You

can consult your local observatory about this issue.

If it is difﬁcult to control the wind vane after installation, you can calibrate through

setting on main unit.

1. Make a compass approach to the wind vane.

2. Calculate the angle between the current direction

and the north direction.

3. Press

For example, inputting the angle value that you

want to set as north. If current direction is 25

degree and you want to set it as north, then you

input 25 degree in the calibration mode. Once

you return to the idol mode, the direction reading

displays 0 degree, which is the north.

You need to calibrate the wind sensor again if you want to relocate the sensor.

MAINTAINANCE

Each sensor of this kit has a durable plastic casing that should retain its luster for

many years. It is better to do regular maintenance to keep the sensors with high

accuracy every half year. Do cleaning the casing only with a soft cloth slightly

dampened with water or a mild soap. Please use screw drivers or wrench to take

some parts off if necessary.

Electrical storms can sometimes cause power surges harmful to electronic

equipment. For your own safety, take caution when using the main unit or doing

maintenance during storms.

TO MAINTAIN THE THERMO/HYGRO SENSOR

1. Remove the rain collector from the rain gauge.

Unscrew the three type B screws from the rain gauge.

3. Unscrew the three screws from the bottom of

the thermo/hygro sensor casing.

4. Clean the casing excluding the one with sensor

by water, and then remove the dust around the

sensor carefully.

5. Install all the parts until they are entirely dried.

If the temperature and humidity readings are

still strange and inaccurate, you need to consider

replacing this sensor, please contacting our customer service for the details.
