The device cannot communicate with the computer:<\/span><\/h4>\n

The connection between the computer port and the device should be evaluated. A suitable USB cable should be used.<\/p>\n

[\/vc_column_text][vc_separator type=”normal”][vc_column_text]\n

The device does not turn on:<\/span><\/h4>\n

Check the device’s fuse. Make sure to use a UPS to properly power the device and prevent the effects of city power fluctuations.<\/p>\n

[\/vc_column_text][vc_separator type=”normal”][vc_column_text]\n

When turning on the tungsten lamp of the optical device, it is not visible from the side of the fan:<\/span><\/h4>\n

The tungsten lamp intensity is set to a low number. The lamp in the device is at the end of its life or has burned out.<\/p>\n

[\/vc_column_text][vc_separator type=”normal”][vc_column_text]\n

Lack of a proper baseline:<\/span><\/h4>\n

Make sure the blank and sample use the same solvent or matrix.<\/p>\n

[\/vc_column_text][vc_separator type=”normal”][vc_column_text]\n

Scope baseline high:<\/span><\/h4>\n

Wash the cell beforehand with a suitable solvent or, if necessary, with acid. The sample should not have suspended particles. There should be no bubbles in the sample (be sure to prepare a uniform sample before spectrometry by tapping the sample cell or giving it time to allow bubbles to escape and place it in the device.<\/p>\n

[\/vc_column_text][vc_separator type=”normal”][vc_column_text]\n

The bottom of the scope is not suitable:<\/span><\/h4>\n

The tungsten lamp has low intensity or is not lit.<\/p>\n

[\/vc_column_text][vc_separator type=”normal”][vc_column_text]\n

The top of the scope is not suitable:<\/span><\/h4>\n

It is necessary to adjust the deuterium lamp. If the intensity is not adequate, the deuterium lamp is off or burned out.<\/p>\n

[\/vc_column_text][vc_separator type=”normal”][vc_column_text]\n

The shift in wavelength is observed:<\/span><\/h4>\n

A spectrum is taken using a samarium or holmium standard sample and the calibration factor is corrected.<\/p>\n
