使用前请先安装上9V电池，去掉探头保护套，需要关机时长按OFF键约五秒即可关闭仪器。 1、光照测量 1. A. 按下ON按钮，打开仪器； 2. B. 对准最高点光源光传感器窗口； 3. C. 目前的光强度将会显示在液晶显示屏; 注意：请不要阻挡光照或给光传感器制造阴影 光照强度对照表 LOW- LOW LOW+ NOR- NOR NOR+ HGH- HGH HGH+ 非常 低 多 略 普通 略 多 高 非常 2、PH范围测量 A.将背面的【PH/℃】按钮推到PH的位置。 B.把探头垂直插入土壤中，需要尽快进行测试。 C.按下【ON】按钮开始测量。 D.测试的PH值将会显示在液晶显示屏上 E.多测量几遍得出需要的确切值。 注意: 1.垂直插入探头，在中间的植物茎的边缘。 2.请轻轻推入土壤，以避免损坏探头。 3.如果测量的土壤太干燥或肥沃不能测出准确的PH值，使用者可以撒点水，半个小时后再测量一遍 PH值对照表 增加酸度 中性 增加碱度 低 3.5 4.0 4.5 5.0 5.5 6.0 6.5 7.0 7.5 8.0 8.5 9.0 高 3、水份测量 A将背面的【PH/℃】按钮推到℃的位置 B尽可能垂直插入土壤中。 C按下NO键开始测量 D测试的土壤湿度情况将会在液晶屏上显示。 4.温度测量； A当测量湿度的同时，土壤温度值将同时显示在液晶显示屏上。 B按下【℃/？H OFF】按钮设置湿度显示是℃或？H。 注意：如果使用者不把探头插入土壤，那么显示的是准确的外部空间环境温度。 湿度对照表 DRY+ DRY NOR WET WET+ 非常干 干 普通 湿 非常湿 Application method of four-in-one soil tester Before using, please install 9V battery, remove the probe cover, and press OFF button for about 5 seconds to close the device. 1. Lighting measurement A. Press the ON button to turn ON the instrument; B. Light sensor window aligned to the highest light source; C. the current light intensity will be displayed on the LCD screen; Note: do not block light or shadow light sensors Light intensity comparison table LOW- LOW LOW+ NOR- NOR NOR+ HGH- HGH HGH+ very low more slightly ordinary slightly more high very 2. PH range measurement A. will be on the back of the [PH /℃] button on the location of the PH. B. The probe is inserted vertically into the soil and needs to be tested as soon as possible. C. press the ON button to start measuring. D. the PH value of the test will be displayed on the LCD screen E. measure it several times to get the exact value you need. Note: 1. Insert the probe vertically at the edge of the plant stem in the middle. 2. Please gently push into the soil to avoid damaging the probe. 3.If the measured soil is too dry or fertile to measure the correct PH, the user can sprinkle some water and measure it again in half an hour PH table Increased acidity neutral Increase alkalinity low 3.5 4.0 4.5 5.0 5.5 6.0 6.5 7.0 7.5 8.0 8.5 9.0 high 3. Water measurement A push back [PH /℃] button to℃ B is inserted as vertically as possible into the soil. C press NO to start measuring D test soil moisture will be displayed on the LCD screen. 4. Temperature measurement; A when the humidity is measured, the soil temperature will be displayed on the LCD screen at the same time. B [℃/？HOFF] button set humidity display is℃or？H. Note: if the user does not insert the probe into the soil, the correct ambient temperature of the outer space is displayed. Humidity table DRY+ DRY NOR WET WET+ Very dry dry ordinary wet Very wet
