What to do if the performance at wavelengths shorter than 320 nm is not stabilized in Jasco V-570 Measuring Instruments?
If the performance at wavelengths shorter than 320 nm is not stabilized in Jasco Measuring Instruments, set the D lamp to “On”.
What to do if the baseline is curved greatly in excess of 1% in Jasco V-570 Measuring Instruments?
If the baseline is curved greatly in excess of 1% in Jasco Measuring Instruments, check if baseline correction is set to “Off”. If it is, set it to “On”.
What to do if the performance at wavelengths longer than 400 nm is not stabilized in Jasco Measuring Instruments?
If the performance at wavelengths longer than 400 nm is not stabilized in Jasco Measuring Instruments, set the WI lamp to “On”.
What to do if the light source is changed over from WI to D, the step height on the baseline is more than 1% in Jasco Measuring Instruments?
If, when the light source is changed over from WI to D, the step height on the baseline is more than 1% in Jasco Measuring Instruments, check if baseline correction is set to “Off” and set it to “On” if it is. Poor adjustment of the light source mirror can also cause this, so readjust the mirror. Another potential cause is that the sample chamber is not securely fitted, or the beam may be incident upon the cell holder; set the sample chamber in the correct position.
