How to fix unstable performance at wavelengths shorter than 320 nm in Jasco V-630?
If the performance at wavelengths shorter than 320 nm is not stable on your JASCO Measuring Instruments, the D lamp might be off. Turn the D lamp on to resolve this issue.
How to fix unstable performance at wavelengths longer than 400 nm in Jasco V-630?
If the performance at wavelengths longer than 400 nm is not stable on your JASCO Measuring Instruments, the WI lamp might be off. Turn the WI lamp on.
What to do if Jasco V-630 does not operate at all?
If your JASCO Measuring Instruments device isn't operating, make sure the cable is securely reconnected. If the issue persists, check the fuse and replace it if it's blown. If a new fuse blows immediately, it indicates an electrical system fault, and you should contact your local JASCO distributor.
What to do if the step height of the baseline is greater than 1% when the light source is changed from WI to D in Jasco Measuring Instruments?
If, when the light source is changed from WI to D, the step height of the baseline is greater than 1% on your JASCO Measuring Instruments, try the following: 1. Set it to “ON” if set to “OFF”. 2. Re-adjust the mirror. 3. Set the standard cell holder in the correct position.
What to do if the baseline is curved greatly in Jasco Measuring Instruments?
If the baseline is curved greatly, in excess of 1% on your JASCO Measuring Instruments, ensure that it is set to “ON” if it is currently set to “OFF”.
What to do if WI lamp does not come on in Jasco V-630 Measuring Instruments?
If the WI lamp does not come on in your JASCO Measuring Instruments, replace the lamp with a new one if it is burnt out.
What to do if D lamp does not come on in Jasco V-630?
If the D lamp does not come on in your JASCO Measuring Instruments, replace the lamp with a new one if it is burnt out.
