Cary 60 Wavelenght Accuracy and Photometric Accuracy Tests Fail

Andreazoltan over 2 years ago

Hi Everyone,

Due to random readings of my samples, i ran wavelength and photometric accuracy test. Both of them fails, do i need to replace the lamp or is it because of the wavelength drive gear?

thanks.
