�.Instructions
1.1 Quick test method
Select a suitable measurement location, avoid stones, and ensure that the steel needle does not touch hard objects. Discard the topsoil according to the required measurement depth, and maintain the original tightness of the soil below. Hold the sensor vertically and insert it into the soil. It is not allowed to shake left and right, it is recommended to measure multiple times to find the average value within a small range of one measurement point.
1.2 Buried survey
Vertically dig a pit with a diameter of> 20cm, insert the sensor steel needle horizontally into the pit wall at a predetermined depth, bury the pit tightly, and stabilize it for a period of time, then you can perform continuous measurement for several days, months, or even longer.
1.3 Precautions
1). All steel needles must be inserted into the soil during measurement.
2). Avoid direct sunlight on the sensor, which will cause excessive temperature. Pay attention to lightning protection in the field.
3). Do not bend the steel needle violently, do not pull the sensor lead wire with force, and do not beat or violently hit the sensor.
4). The protection grade of the sensor is IP68, which can soak the sensor in water.

Calculation Method
Wind Speed Sensor
1 Calculation current mode outputs the converted signal
Range 0 ~ 30m / s, 4 ~ 20mA output when the output signal is 12mA, the current wind speed is calculated. Winds range span of 30m / s, to express 16mA current signal, 30m / s / 16mA = 1.875m / s / mA, i.e., the current wind speed variations 1mA 1.875m / s. So the measured values can be measured Calcd 12mA-4mA = 8mA.8mA * 1.875m / s / mA = 15m / s, the current wind speed = 15m / s.
2 voltage-converts the output signal calculation
Range 0 ~ 30m / s, 0-10V output to an example, when the output signal of 5V, the current wind speed is calculated. Winds range span of 30m / s, with a 10V voltage signal expression, 30m / s / 10V = 3m / s / V, i.e., the voltagecorresponding to the wind speed change by 1V 3m / s. Measurement 5V-0V = 5V. 5V * 3 / m / s / V = 15m / s. The current wind speed is 15m / s.

Denifition:
Flatbed Digital printing is the reproduction of digital images using inkjet printing, typically on plastic or paperboard, although a wide variety of materials can be printed (common, photographic paper, film, cloth, plastic, etc.). Flatbed digital printers use inks made of acrylic monomers that are then exposed to strong UV-light to cure, or polymerize them. This process allows for printing on a wide variety of surfaces such as wood or metal, carpet, tile, and even glass. The adjustable printing bed makes it possible to print on surfaces ranging in thickness from a sheet of paper often up to as much as several inches.
