| 光源
光源可以放置在球體中（如果要測試其光譜）或電子控制系統（檢查其耐用性）。 |

1. 測量值 :
◆電流的均方根值，精度為 1 mA。
◆光源上的 rms 電壓，精度為 1 V。
◆電源的均方根電壓值，
◆負載充電的有功功率精度為 1 W。
◆負載充電的無功功率精度為 1 var。
◆ cosΦ 精度為 0.02°。
◆球體溫度精度為 0.5°C。
2.每秒鐘同步採集64個電壓值：
◆瞬時電壓。
◆光源電壓。
◆光源電流。
3.該裝置有一個內置的相位控制器，用電腦控制。 (能夠通過短路把控制器關閉。)。
它的調節範圍 - 從0%到100% ( 步階1% )。也可以連接你自己的外部調節器。
4.為了檢查光源的耐久性，分別自定義了燈光關閉和開啟的時間。
兩者的範圍從0.2秒到1000小時。

- Measured values:
o rms value of current with an accuracy of 1 mA,
o rms voltage on the light source with an accuracy of 1 V.
o rms voltage value of mains.
o active power charged by load with an accuracy of 1 W.
o reactive power charged by load with an accuracy of 1 var.
o cosΦ with an accuracy of 0,02°.
o temperature in the sphere with an accuracy of 0,5°C. - Synchronously with every second voltage period are collected 64 values of:
o instantaneous voltage,
o voltage on the source of light.
o current flowing through the source. - The device has a built-in phase controller, controlled with a PC. (There is possibility to turn the controller off by short circuit.)
Scope of it’s regulation – every 1% from 0% to 100%. It is also possible to connect your own external regulator. - For checking the durability of the light source, time when light is off and on is defined separately.
For both the range is from 0,2 s to 1000 h.
