(FTIR) The signal intensity of the power spectrum remains zero.

Reason
  1. The light source is broken.
  2. The fuse has blown.
  3. Selection of the detector is wrong.
  4. Something that intercepts the light path is in the sample compartment.
  5. The infrared interference has shifted significantly.

 

Solution
  1. The light source is broken.
    • The infrared source has become inoperative if the "Lamp" on the status window is red when the instrument is initialized in LabSolutions IR.
    • If the light source is broken, the infrared light source needs to be replaced by service personnel. Please contact a Shimadzu sales or service representative.

  2. The fuse has blown.
    • The fuse on the CPU board or in the inlet has blown if the light source still does not light after replacing the light source. Please contact a Shimadzu sales or service representative to replace the power board.
  3. Selection of the detector is wrong.
    • Select collect detector. Set "standard" for inside detector or "option2" for IR microscope and Second sample compartment.
  4. Something that intercepts the light path is in the sample compartment.
    • Remove any intercepting items or set a correct sample on the accessory.
  5. The infrared interference has shifted significantly.
    • Click [Instrument] on the scan toolbar in LabSolutions IR and execute [Auto-Adjust].
      If the problem is not solved, please contact a Shimadzu sales or service representative.
