HP822 老化光衰测试仪
- LED在做老化光衰测试时需要长时间的点亮,每间隔一定时间进行一次光衰数据记录,费时费力。HP822在设置好采样时间间隔后，可自动进行光衰数据记录，并保存在仪器内部，老化时间周期完成后，通过RS-232串口与电脑连接，光衰测试软件读出光衰数据并绘制光衰曲线。
- 老化时间和光衰数据断电自动保存,来电继续工作。
HP822 LED aging and optical attenuation tester
Traditionally it is required to record photo attenuation data for a long time, now you are free for HP822 can help you to solve this problem. It can save all the data after sample interval preset, and output them via RS-232 interface after work finished. The application software can read the data, can draw the curve according.
