communication. During the self-checking, the instrument cannot communicate with computer and the
software will prompt the communication was failed. Please exit the software, after self-checking is
finished (the sound of rotation is stopped), rerun the software and select the actual RS232 port, the
communication will be successful.
You can use software to operate the instrument to automatically change the wavelength, scan spectrum,
switch gratings and change filters (if you have bought 7IFW6 filter wheel from us). Please refer to the
software manual.
Note: To avoid damage of computer and instrument, please do not plug / unplug cables when the
instrument is still power on.

Fiber adapter
If you have bought the adapter for SMA905 fiber from us, please replace the cover of the slits with the
fiber adapter and connect the fiber directly.
Nitrogen connector
To avoid the absorption of air, you can fill the monochromator with nitrogen in ultraviolet and near
infrared band to improve the efficiency. There is a specific nitrogen connector with the
monochromator.
When you need to use it, remove the cover and install the nitrogen connector, then connect the
nitrogen pipe. Note: The nitrogen connector can’t be used for other gases.
The nitrogen is a kind of non-toxic, pollution-free, non-irritating and non-corrosive gas, so you can keep
filling it during the whole experiment to keep the nitrogen concentration and positive pressure in the
instrument. The excess gas will leak off through gaps.
