Introduction to common faults and troubleshooting methods for infrared spectrometer maintenance:
If the infrared spectrometer cannot work normally, you can first start the self-diagnosis function of the instrument to check the operating status of some Components of the instrument. Or, depending on the abnormality of the instrument, refer to the instrument's instruction manual to troubleshoot.
If the spectrometer hardware is found to be damaged, a maintenance technician should be requested to come to the site to correct the problem. If the cause of the failure cannot be found, the maintenance engineer should communicate with the maintenance engineer as soon as possible and the equipment failure information should be conveyed in a timely manner.
This allows engineers to roughly determine the cause of the failure and prepare the necessary spare parts before sending them for repairare on site.
If the cause of the error is not a hardware problem and can be resolved through technical measures such as adjusting and resetting the spectrometer parameters, you can fix the problem yourself.
Below are some common errors and troubleshooting methods.
The energy of the interference pattern of the infrared spectrometer is low, resulting in an unsatisfactory signal-to-noise ratio.
Possible reasons:
1. The collimation of the optical path is not set correctly or the position of the non-intelligent infrared accessory is not adjusted to the set correct position;
2. The infrared light source is damaged or the energy is exhausted
3. The detector is damaged or the MCT detector is defective no liquid nitrogen;
4. The beam splitter is damaged;
5. The mirror surfaces of different infrared reflectorsdevices or infrared accessories are too dirty;
6. Aperture The aperture is too small or the signal amplification is too small;
7. There is an attenuator in the circular beam path.
Troubleshooting method:
1. Start the light path automatic alignment program. If you use a non-smart infrared accessory, manual alignment is also required;
2. Replace the infrared light source;
3. Ask a service technician to check the detector and replace it if necessary (detector). Damage is most likely due to moisture
Therefore, care should be taken to keep the instrument compartment dry after replacement. For the MCT detector, liquid nitrogen can be added and then checked again
New inspection;
4. Ask a maintenance technician to check the beam splitter e.gu Check and replace if necessary (Damage to the beam splitter is likely to be caused by moisture
or cracks caused by collision during replacement, so you should keep the instrument chamber dry after replacement and when removing or Be very careful when inserting);
7. Remove the attenuator in the beam path.
Possible reasons:
1. The beam splitter is not repaired or damaged;
2 . The computer and the optical table could not connect.
3. The control board is damaged.
4. The output voltage of the spectrometers is faulty abnormal;
5. There is a problem with the operating software;
6. The room temperature of the spectrometer is too high or too low;
7. The detector is completely damaged;
8. The He-Ne laser does not work or the energy is severely attenuated.
Troubleshooting Method:
1. Repair the beam splitter. If the beam splitter is damaged, please ask a maintenance technician to check and repair it. Replace the beam splitter if necessary.
Damage to the beamsplitter is most likely caused by moisture or cracks caused by collisions during replacement.
Care must be taken to keep the instrument compartment dry. Be very careful when taking it out or loading it into the instrument);
2. Check the connection between the computer and the optical table and lockel the interface and restart the optical table and calculation;
3. Contact the maintenance technician or ask the maintenance technician to check the control board and replace it if necessary (check After replacement, check again whether There are problems with the work efficiency of the regulated power supply and the power supply of the instrument compartment); 4. Check the indicator lamp on the spectrometer panel. Diagnostic program that can start diagnosis, check whether the output power supply is normal, solve the cause of the error and contact the maintenance technician for solutions;
6. Adjust the room temperature via the air conditioner. 7. Replace the detector.
8. Check whether the He-Ne laser is working properly. Please ask a maintenance technician to repair the problem in time.
(3) The energy of the interference pattern is too high, resulting in overflow
Possible reasons:
1. Light The aperture is too large or the signal amplification factor is too high;
2. The moving speed of the moving mirror is too slow.
Troubleshooting method:
1. Reset the aperture or signal gain multiplier to an appropriate value;
2. Reset the moving speed of the moving mirror.
