红外辐射计常见问题解答
低或不稳定的读数通常是由于传感器窗口堵塞，遮挡污垢或其他有机沉积物。您可能希望执行窗口清洁以查看读数是否有所改善。作为参考，当我们获得红外传感器回来重新校准时，我们首先使用蘸水或醋，如醋中蘸水的棉签清洁传感器。醋有助于溶解钙和盐沉积物。使用棉签清洁内线和传感器窗口。小心不要对窗户施加太大的压力，因为它实际上可能划伤抗反射涂层。然后，我们使用溶剂（例如丙酮或乙醇）对传感器窗口进行第二次清洁。很多次，这将在规范中带来传感器的读数。如果没有，则可能需要将传感器发送回重新校准。
SI-100 series radiometers have sensitivities in the microvolt range, approximately 20 to 60 µV per C difference between target and detector (depending on specific model). Thus, a compatible measurement device (e.g., datalogger or controller) should have resolution of at least 3 µV (0.003 mV), in order to produce temperature resolution of 0.05 C.
Field of View (FOV) is widely dependent on the application. Essentially, you want to select a FOV model that only “sees” what you want the temperature of. A simple FOV calculator for determining target dimensions based on infrared radiometer model, mounting height, and mounting angle, is available on the远地点网站and in theapp store.
It is recommended that infrared radiometers be recalibrated every two years. SeeRecalibration and Repairsfor details regarding return of sensors for recalibration
当传感器连接到具有高输入阻抗的测量装置时，通过缩短电缆或在附加电缆上拼接或在现场附加电缆上拼接来改变传感器输出信号。测试表明，如果测量装置的输入阻抗为10米或更高，则距离辐射计校准的效果可忽略不计，即使在加入50米的电缆后也是如此。Apogee Model Si系列红外辐射仪使用屏蔽双绞线电缆，可最大限度地减少电磁干扰。这对于电磁嘈杂环境中的长引线长度尤其重要。有关如何制作防风电缆拼接的信息点击这里
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.
ApoGee Si-100系列红外辐射仪中的辐射检测器是一种自动装置，其输出与检测器和目标表面之间的辐射平衡成比例的电压信号。可以使用具有微伏（μV）分辨率的电压表来实现对探测器功能的快速简便检查。将电压表的正极从传感器和负引线（或共同）从传感器连接到黑色电线。将传感器引导朝向表面，温度明显不同于检测器。如果表面比检测器比检测器更冷，μV信号将是负的，如果表面比检测器温暖。
The SI series is considered to be self-powered with each sensor having custom calibration coefficients. Average sensitivities are 60 (SI-111), 40 (SI-121), 20 (SI-131), and 50 (SI-1H1) μV C-1. A voltmeter that can resolve the given sensitivities is required. A high resolution ohmmeter will also be needed to measure the thermistor's resistance. After the mV response and thermistor resistance are measured, they will need to be combined with the custom calibration coefficients to produce the given target temperature. Calculation details and equations are available in the sensor手动的。了解更多，点击这里for a knowledge base article on how to take IRR temperature measurements without a datalogger.
The AC-100 communication cable 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 cables will not work. 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这里.
不可以。所有的Apogee仪表（Mo，MP，MQ和MU系列）都具有内置于仪表中的传感器，或者通过两米电缆连接。如果您只订购传感器（SI，SO，SP，SQ和SU系列），您需要拥有自己的数据记录器（或取决于传感器，电压表）以从传感器收集信息。
尽管可以将附加电缆接合到单独的传感器，但请注意，电缆线直接焊接到仪表的电路板中。应注意拆下仪表的后面板，以便在额外的电缆上接入电路板并拼接，否则需要在仪表和传感器头之间进行两种接头。点击这里有关如何扩展传感器电缆长度的更多详细信息。
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 themanual.
| 呃1：Battery voltage out of range. | 使固定：replace CR2320 battery and perform master reset. |
| 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 voltage below minimum. | 使固定：replace CR2320 battery and perform master reset. |
The meter takes a CR2320 coin cell battery.
可以执行主重置，以纠正问题。*注意：主重置将删除存储器的所有记录测量值。
首先按下电源按钮，以便激活LCD显示屏。虽然仍然有动力，请将电池从支架中滑出，这将导致液晶显示器淡出。几秒钟后，将电池滑回支架。LCD显示屏将闪存所有段，然后显示修订号。这表示执行了主复位，并且显示器应返回正常情况。
No – user should record the starting time when the meter is placed in LOG mode and take note of time when sampled readings are taken.
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).
当在SMPL模式下按下样本按钮录制最多99次手动测量（LCD显示屏的右上角的计数器表示保存的测量值）。
