We offer custom cable lengths of our high quality cable and splice kits that can be ordered at the time of purchase or at a later date.
使用提供的尼龙安装螺钉将传感器安装到坚固的表面上。为了精确测量水平面上的PPFD入射,传感器必须是水平的。最高点AL-100 Leveling Plateis recommended for this purpose. To facilitate mounting on a cross arm, an ApogeeAM-110 Mounting Bracket建议使用。
为了最大限度地减少方位误差,传感器的安装应使电缆指向北半球的正北或南半球的正南。方位角误差通常小于1%,但通过适当的电缆方向可以很容易地将其最小化。
除了使电缆指向最近的电极外,传感器的安装还应确保障碍物不会遮挡传感器。
这个AC-100 communication cable accessory is used to download saved measurements from any of our handheld meters. This USB cable includes a built-in circuit board to convert voltage levels to be compatible with the meter. Normal USB to mini-USB cables will not work; you must use the AC-100 communication cable. The AC-100 also comes with a flash drive that includes the necessary computer software, drivers, and instructions. If you already have the AC-100 and just need the software files please click在这里.
Err 1:蓄电池电压超出范围。 | 修正:更换CR2320电池并执行主复位。 |
Err 2:传感器电压超出范围。 | 修正:perform master reset. |
Err 3:Not calibrated. | 修正:perform master reset. |
错误4:CPU电压低于最小值。 | 修正:更换CR2320电池并执行主复位。 |
首先按下电源按钮,以便激活LCD显示屏。在仍通电的情况下,将电池从支架中滑出,这将导致LCD显示屏淡出。几秒钟后,将电池滑回支架。LCD显示屏将闪烁所有部分,然后显示修订号。这表示已执行主复位,显示屏应恢复正常。
SQ-420和SQ-520有一个“浸没设置”,通过远地点连接软件将浸没设置应用于传感器读数。选择浸没设置时,无需对水下测量进行校正。
All other Apogee meters and sensors need to have their measurements multiplied by their respective immersion effect correction factor when used to take underwater measurements. Original quantum sensor models should have their measurements multiplied by 1.08 and full-spectrum models should have their measurements multiplied by 1.32. Additional information on underwater measurements can be found在这里.
When a quantum sensor that was calibrated in air, such as Apogee's, is used to make underwater measurements, the sensor reads low. This phenomenon is called the immersion effect and happens because the refractive index of water (1.33) is greater than air (1.00). The higher refractive index of water causes more light to be backscattered (or reflected) out of the sensor in water than in air (Smith, 1696; Tyler and Smith, 1970). As more light is reflected, less light is transmitted through the diffuser to the detector, which causes the sensor to read low. Without correcting for this effect, underwater measurements are only relative, which makes it difficult to compare light in different environments.
这个Apogee full-spectrum quantum sensor (model SQ-500) is more spectrally accurate than the original quantum sensor (model SQ-120), but the unique optics (mainly the shape) cause the immersion effect to be larger for the new sensor. Underwater PAR measurements collected using a full-spectrum sensor can be corrected by multiplying the measurement by 1.32; measurements collected using an original Apogee sensor should by multiplied by 1.08.
有关如何确定这些乘数的详细信息,请阅读量子传感器远地点浸没效应修正系数白皮书。
第一步:从连接传感器和打开软件开始,使用屏幕左下角的齿轮图标导航到校准窗口。
第二步:在乘法器字段中键入“FACTORY”,然后按键盘上的回车键。校准系数将重新出现,灰色的“更新固件”按钮将变为可用。
第三步:点击“更新固件”按钮。应打开一个文件选择窗口。固件文件位于安装Apogee Connect的目录位置(在我们的机器上,这是:C:Program files(x86)\Apogee Connect\dist\update\u tools)。如果您的SQ-420的序列号是1258或以下,请从该目录位置选择“SQ420\u V2.txt”。如果序列号为1259或更高,请选择“SQ420_v12.txt”,然后按照提示操作。(请注意,如果在完成这些步骤后安装v12仍有问题,请返回并尝试v7)
第四步:固件现在已更新,传感器应正常工作。
