程，无精度损失 ) • 载荷精度为指示载荷的 0.5% • 500 Hz 数据采样频率 • 全面软件控制 • 自动传感器识别
安全
关系到安全的关键功能由控制器直接实现，而不是通过计算机软件间接实现。这样能对紧急情况和限位开关做出最快的反应，一旦有这些情况发生，控制器会检测到试验过程中传感器断开，停下横梁。如果计算机关机或者软件出现错误，机器会自动切换到等待模式。力传感器达到满载荷的 105% 时会有自动过载保护。另外，用户可以在软件里设置软极限。
数据完整性和可靠性
传感器自动识别，校准和平衡大大加快了测试速度，保证了测试数据的一致和精确。使用优化的零部件，板式安装接头和可靠性高的零部件，减少了维护时间和费用，提高了可靠性。先进的数字控制系统使所有通道的数据采集同步达到 500Hz。即使在材料屈服阶段或者剥离，撕裂等应用中快速发生变化的状况，也能保证数据的真实可靠。每次测试的数据都会自动保存在计算机的硬盘中，即使突然断电，数据结果也不会丢失。
我们的使命是成为公认的力学性能试验设备世界领导者。我们的目标是通过不断地技术创新提供高品质的产品、专业的技术支持和世界水平的服务从而使得我们的用户获得拥有英斯特朗产品的最佳体验。

Make sure the adaptor is plugged in.•Make sure that the Cameras and Receiver are both ON.•Make sure that the camera is in range of the Receiver.•If using the battery adaptor, try replacing the BatteriesThere is Interference with the Camera Picture. •Make sure that each camera is within range, and that there are no large obstructions or interference •Try repositioning the camera, receiver or both to improve the reception.There are problems with the Audio. •Ensure that the volume on the TV is ON•Make sure that the sound is occurring within range of the Camera Microphone•If the unit emits a loud screeching noise (feedback), move the camera or receiver farther apart.Appendix #1 - Receiver SpecificationsENGAppendix #3 – Digital Wireless Technology Appendix #3 – Digital Wireless TechnologyThe Digital Wireless signal transmission type used by the Lorex LW2100 series is also known as FHSS –Frequency Hopping Spread Spectrum. This type of signal is highly resistant to deliberate jamming as itgenerates a channel hopping sequence using an algorithm generated by the receiver system.The 2.4GHz (2.400-2.483Ghz) band is being divided into sections or paths of 2MHz per section, and eachsecond the transmission signal hops hundreds of times in a specified sequence within this frequencyrange. The overall bandwidth required for frequency hopping is much wider then 2MHz however because transmission occurs only on a small section of this bandwidth at any given time, the signal beingtransmitted does not suffer from greatly reduced signal degradation and also avoids blocked paths otherdevices who act as sources of competing signals. The strength of the signal being transmitted is set to befrom 13.5-16dBm, which is much higher then the analog transmission signal allowed by authoritiesaround the Globe (see next 2 slides for a comparison).When an image is captured by the camera it is instantly converted from an analog to digital signal andpackaged into small packets. With each successful transmission via the 2Mhz paths discussed above, thepackets of information containing images are delivered to the receiver and decoded into analoginformation. The information can then be displayed on devices that are connected to the wireless receiver(RX).A device pairing process is required to synchronize the transmitter (TX, Camera) and the receiver (RX).This allows the transmitter and receiver to be on the same frequency and use the same algorithm forfrequency hopping. This ensures that only the paired transmitter and receiver can maintaincommunication signal by hopping to the same frequency paths at the exact same time. As a result, thechance that other devices within the same frequency range are on the same frequency, at the same timeand in the same order is extremely unlikely. Note that the pairing process is already done at the factoryfor products that ship within the same packaging. Only when add-on devices are purchased is a pairingprocess required.。

Taking advantage of this, the m ethod called near infrared spectroscopy is used to non-invasively m easure the oxygenation levels of deep tissue in the brain, etc., and the oxygen concentration levels in blood.The NIRO-200 uses two very practical m ethods of near infrared spectroscopy.[ SRS method (Spatially Resolved Spectroscopy ) ]The Tissue Oxygenation Index (TOI ) and Normalized Tissue Hem oglobin Index (nTHI ) are calculated based on the change in the amount of light attenuation.[ MBL method (Modified Beer-Lambert ) ]The concentration change in the oxygenated hem oglobin (∆O 2Hb ), deoxygenated hem oglobin (∆HHb ), and total hemoglobin (∆cHb ) are calculated based on the tim e change of the light attenuation at the measurement location.• Monitoring brain oxygenation during heart surgery, etc.• Patient monitoring in ICUs, CCUs, and NICUs• Various clinical studies related to the responsiveness of oxygenation and blood metabolism in the brain• Study of muscle tissueoxygenation for sports medicine, rehabilitation, etc.Near InfraredOxygenation MonitorEasy-attachable probesThe probe holder is very small and can be in-stalled to small areas.

希玛照度计参数

希玛照度计参数
希玛照度计是一种测量光照强度的仪器，常用于室内照明设计和照明效果评估。

其主要参数包括测量范围、分辨率、准确度、响应时间等。

测量范围一般为0-200,000勒克斯，可适用于不同场合的测量需求。

分辨率一般为1勒克斯，也有些高精度的希玛照度计可以达到0.1勒克斯的分辨率。

准确度是指希玛照度计测量结果与实际光照强度之间的偏差，通常为±（3%+2勒克斯）。

响应时间是指希玛照度计从暗到亮或由亮到暗的响应速度，一般为0.4秒左右。

除此之外，希玛照度计还有显示屏幕、数据记录、自动关机等功能，方便用户使用和数据处理。
