An uknown error message appears when I try to do the instrument validation (abscisse, ordinate and spectral background noise) of a Perkin Elmer FTIR spectrophotometer, and the validation process stops. It happens when using a PE standard or the AVP internal standard option. However, when I try to validate the instrument using the AVP internal standard option, the error message appears before I run the scanning.
On th other hand, the software allows performs the calibration, and it is OK.
Anyone could help me, please?
