Pyranometer常见问题解答

Apogee提供硅电池和热电探测器粘膜仪。从大图形的角度来看，热电堆仪在所有条件下比硅细胞模型更准确。

一般而言，热量粘连仪具有较大的光谱范围（这使得它们在所有大气条件下更准确），输出信号较小，响应时间更长，并且比硅 - 细胞探测器更昂贵。

硅 - 细胞粘连仪较便宜且更快的响应，但在多云条件下误差较高。下表是散脂硅 - 细胞吡喃大学仪和热电堆吡喃大学计的一般规格的比较：

规格	Silicon-cell Detector	热电探测器
校准不确定性	±5％	±5％
余弦反应	±5％低于75°的天顶角	Less than 30 W m-2在80°天顶角
云引起的错误	+ 10至15％（所有硅 - 细胞比克仪共同）	±2％
光谱范围（50％）	360 to 1120 nm	385 to 2105 nm
Base Model Output Voltage	0到350 mv = 0到1750 w m-2	0 to 114 mV = 0 to 2000 W m-2
Response Time	不到1毫秒	0.5秒

所有SP-100，SP-200和MP系列硅电池哒烟灰使用相同的硅电池检测器。您需要的型号取决于哪个输出与您的数据记录器兼容。型号下面列出了它们的输出：

SP-110：0到350 mv = 0到1750 w m^-2

SP-230：0 to 250 mV w/Heater = 0 to 1750 W m^-2
*注意：SP-230具有与SP-110相同的电压输出，但具有内置的加热器和DELRAN安装支架，用于切割或寒冷的天气应用中的部署（例如霜，雪，雨夹雪，冻雨）。

SP-212:0到2.5 v = 0到1250 w m^-2

SP-215:0到5.0 v = 0到1250 w m^-2

SP-214:4 to 20 mA = 0 to 1250 W m^-2b0b体育app下载

SP-420:USB/software

MP-100：传感器集成到具有数字读数的手持式仪表顶部

MP-200：Sensor attached to a handheld meter with digital readout

*上面的范围是标准的，并建成库存。如果您需要比上市的范围更大，请联系您对特定要求的报价的技术支持。

为了最大限度，我们通常推荐所有传感器每两年重新校准一次。根据您的要求，您可能希望在重新校准周期之间等待更长时间。透明的天空计算器可以用作快速参考，以确定Pyranomets和量子传感器是否需要重新校准，请单击here有关清晰的天空计算器的更多信息。有关如何发送传感器进行校准和定价的其他信息，请单击here。

异丙基（摩擦）醇和Q尖端的工作良好，用于清洁传感器区域。小心不要在顶部上使用磨料布，因为它将划伤传感器的表面。超细纤维袋也很好地工作。

是的，如果适当拼接，来自传感器的信号不受额外电缆拼接的影响。我们已经测试了最多100米的电缆拼接。有关如何创建适当防水拼接的信息，请访问我们的教学网页orB0B体育平台下载 。

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.

Mount the sensor to a solid surface using the nylon mounting screw provided. To accurately measure total shortwave radiation incident on a horizontal surface, the sensor must be level. An ApogeeAL-100平整板is recommended for this purpose. To facilitate mounting on a cross arm, an ApogeeAM-110 Mounting Bracket被推荐。

To minimize azimuth error, the sensor should be mounted with the cable pointing toward true north in the northern hemisphere or true south in the southern hemisphere. Azimuth error is typically less than 1 % but is easy to minimize by proper cable orientation.

In addition to orienting the cable to point toward the nearest pole, the sensor should also be mounted such that obstructions do not shade the sensor.

*太阳能应用:我们的许多太阳能客户我nquire about if they should mount their sensor horizontally or in the plane-of-array. Because most applications are verifying panel efficiency/panel soiling we recommend the plane-of-array, however, every application is different and some may require horizontal installation.

绝对地。我们有很多客户购买我们的传感器，以便在海洋生物学和水文等水下应用中持续部署。SP系列粘性仪传感器完全密封，水密和电缆也可以浸没水下。
注意：无法浸没MP系列手持式仪表（屏幕是飞溅的）。MP-200的传感器头和电缆可以浸没。

The SP-110 is considered to be self-powered and has been calibrated to 5.0 W m^-2每MV。使用带有MV设置的电压表允许更好的分辨率。将电压表的正极连接到绘制计的红色电线和电压表的负极引线到绘制仪的黑线。一旦您从传感器读取MV输出，将此读数乘以5.0。这会给你w m^-2来自传感器的输出，也称为辐照度。

The 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 meters-normal USB to micro-USB cables will不是工作。AC-100还配备了闪存驱动器，包括必要的计算机软件，驱动程序和指令。如果您已经拥有AC-100并只需需要软件文件，请点击here。

Although it is possible to splice additional cable to the separate sensor, note that the cable wires are soldered directly into the circuit board of the meter. Care should be taken to remove the back panel of the meter in order to access the board and splice on the additional cable, otherwise two splices would need to be made between the meter and sensor head.

Error codes will appear in place of the real-time reading on the LCD display and will continue to flash until the problem is corrected. For steps on completing a fix please refer to the手动的。

呃1：电池电压超出范围。	使固定：更换CR2320电池并执行主复位。
Err 2:传感器电压超出范围。	使固定：perform master reset.
Err 3:Not calibrated.	使固定：perform master reset.
Err 4:CPU电压低于最小值。	使固定：更换CR2320电池并执行主复位。

The meter takes a CR2320 coin cell battery.

A master reset can be performed that may correct the problem. *Note: a master reset will erase all logged measurements from memory.

First press the power button so that the LCD display is activated. While still powered, slide the battery out of the holder, which will cause the LCD display to fade out. After a few seconds slide the battery back into the holder. The LCD display will flash all segments and then show a revision number. This indicates the master reset was performed and the display should return to normal.

不 - 用户应记录仪表放置在日志模式下的开始时间，并在采集采样读数时注意到时间。

When in LOG mode the meter will power on/off to make a measurement every 30 seconds. Every 30 minutes the meter will average the sixty 30 second measurements and record the averaged value to memory. The meter can store up to 99 averages and will start to overwrite the oldest measurement once there are 99 measurements. Every 48 averaged measurements (making a 24 hour period), the meter will also store 99 integrated daily totals in moles per meter squared per day (mol m^-2D.^-1).

When in SMPL mode press the sample button to record up to 99 manual measurements (a counter in the upper right hand corner of the LCD display indicates the total number of saved measurements).
