CAUTION! This unit was tested with shielded cables on the peripheral devices.
Page 30: Functional Description
✔ ✔ The transmitters use Vaisala WINDCAP sensor technology for wind measurement. The wind sensor has an array of 3 equally spaced ultrasonic transducers on a horizontal plane. The unit determines wind speed and wind directions by measuring the time it takes the ultrasound to travel from one transducer to the other two.
Page 31: Precipitation Measurement Principle
✔ ✔ ✔ The transmitter uses Vaisala RAINCAP Sensor 2 technology in precipitation measurement. The precipitation sensor comprises of a steel cover and a piezoelectrical sensor mounted on the bottom surface of the cover. The precipitation sensor detects the impact of individual raindrops. The signals from the impact are proportional to the volume of the drops.
Page 32: Ptu Measurement Principle
WXT530 Series User Guide M211840EN-G Precipitation current intensity is internally updated every 10 seconds and represents the intensity during the 1-minute period before requesting/automatic precipitation message sending (for fast reactions to a rain event, during the first minute of the rain event, the intensity is calculated over the period rain has lasted in 10-second steps instead of a fixed period of 1 minute).
Page 33: Heating
Chapter 3 – Functional description In case of capacitive sensors, the measurement principle of the transmitter is based on an advanced RC oscillator and reference capacitors against which the capacitance of a sensor is continuously measured. The resistive Pt1000 sensors are measured with a voltage divider circuit incorporating a reference resistor and a stable voltage source.

Chapter 4 – Installation Figure 12 WXT530 North arrow Wind direction can be referred either to true North, which uses the Earth’s geographic meridians, or to the magnetic North, which is read with a magnetic compass. The magnetic declination is the difference in degrees between the true North and magnetic North. The source for the magnetic declination should be current as the declination changes over time.

Page 53: Power Management
The maximum size of the fuse or circuit breaker is 2 A. 1.6 A is also enough for guaranteed operation. Overcurrent limitation or protection can also be built into the power supply. This limitation applies to Vaisala cables with 0.25 mm conductors. The minimum conductor cross section area is 0.25 mm for WXT530 series instrument with heating.

Chapter 5 – Power management Measurement Consumption RS-485 and RS-422 Consume about the same amount of power as RS-232. With long data data interfaces cables the data consumption during data transmission can be much higher, especially when termination resistors are used. On the other hand, the RS-485 driver is in high impedance state when not transmitter.

Page 67 Chapter 5 – Power management Use a shielded cable and ground the external wiring shield. For the SDI-12 mode, the Data in/out (Tx) and Data in/out (Rx) signals must be connected internally by looping pins 5 and 7, or, externally by looping the M12 pins 1 and 7.
Page 68: Data Communication Interfaces
600 m (2000 ft) or longer, you must use termination resistors at both ends of the line. The WXT530 series transmitters with serial communication interface have built-in termination options. Plain resistor (R) termination or termination with resistor connected series with capacitor can be selected with jumpers.
Page 69: Figure 23 Termination Jumper Positions
Chapter 5 – Power management Figure 23 Termination jumper positions NO, no termination R, 121 Ω termination RC, 121 Ω series with 4.7 nF capacitor termination The termination resistors increase power consumption significantly during data transmission. If low power consumption is necessary, connect a 0.1 uF capacitor in series with each external termination resistor or use internal RC termination.
Page 70: Connection Options
Data in/out lines have not been combined inside the transmitter. 6.2 Connection cables The following table shows the connection cable options for the WXT530 series transmitters. The USB cables connect the transmitter to a PC using a standard USB port. The USB cables also provide operation power to the transmitter when connected.
Page 71: Connecting With Service Cable
If you use heating, you need a 24 V DC power supply with the 50-meter cable. If you use the USB RS-232/RS-485 cable for a permanent installation, Vaisala recommends that you use the WSP152 surge protector to protect the host PC against surges entering through the USB port.
Page 72: Figure 24 Service Cable Connection
3. Select the COM port reserved for the USB cable and select the following default communication settings: 19200, 8, N, 1. 4. Use the Vaisala Configuration Tool or a terminal program to make the configuration changes. 5. When removing the service cable, support the transmitter while pulling the 4-pin M8 connector for service port.
Page 73: Connecting Through M12 Bottom Connector Or Screw Terminal
Chapter 6 – Connection options 6.3.1 Connecting through M12 bottom connector or screw terminal You can check and change the device settings through the 8-pin M12 bottom connector or screw terminal. To do this, you must know the device communication settings, have a suitable cable between the device and the host, and, if needed, use a converter (for example, RS-485/422 to RS-232, if the host is a PC).

Chapter 7 – Retrieving data messages In SDI-12 v1.3 Continuous measurement mode (aXU,M=R) the sensor makes measurements at configurable update intervals. The aD command following the aM, aMC, aC, or aCC command always returns the latest updated data. Thus in aXU,M=R mode issuing consecutive aD commands can result in different data strings if the values are updated between the commands.
