Why is noise high in Jasco V-570?
- B
  Benjamin HarrisSep 12, 2025
  High noise in Jasco Measuring Instruments can occur for several reasons: * The light may not be correctly hitting the center of the entrance slit; if this is the case, adjust the light source mirror. * The spectral bandwidth might be too small; try increasing it. * The absorption of the solvent on the reference beam side may be too high; replace the solvent with a more suitable one. * The lamp may have deteriorated; replace it with a new one.

  If your Jasco Measuring Instrument isn't operating, first ensure the power cable is securely plugged into the outlet. If it's disconnected, replug it. If the issue persists, remove the power cable and check the fuse in the main unit. Replace the fuse if it's blown. If the fuse blows immediately after replacement, it indicates a fault in the electrical system.

What to do if the light source changeover from WI to D causes a baseline step height of more than 1% in Jasco V-570 Measuring Instruments?
- B
  Brandon MartinezAug 23, 2025
  If you observe a baseline step height exceeding 1% when switching the light source from WI to D in your Jasco Measuring Instruments, there are several potential causes: 1. The baseline correction might be set to “Off”. Check this setting and set it to “On” if necessary. 2. The light source mirror might be poorly adjusted. Readjust the mirror. 3. The sample chamber might not be securely fitted, causing the beam to hit the cell holder. Ensure the sample chamber is correctly positioned.

Why is the baseline curved greatly in excess of 1% on Jasco Measuring Instruments?
- G
  Gregory JamesAug 26, 2025
  A greatly curved baseline (in excess of 1%) in Jasco Measuring Instruments may be due to the baseline correction being set to “Off”. Check this setting and set it to “On”.

How to fix unstabilized performance at wavelengths shorter than 320 nm on Jasco Measuring Instruments?
- J
  Joseph BruceAug 27, 2025
  If the performance at wavelengths shorter than 320 nm is not stabilized on your Jasco Measuring Instruments, the D lamp might be “Off”. Set the D lamp to “On.”

What to do if WI lamp does not light in Jasco V-570?
- J
  John JacksonSep 1, 2025
  If the WI lamp does not light in your Jasco Measuring Instruments, check if the lamp has burnt out. If it has, replace it with a new one.

What to do if Jasco Measuring Instruments do not operate at all?
- J
  Joel SingletonSep 3, 2025
  If the Jasco Measuring Instruments do not operate, first, check if the power cable is securely plugged into the outlet; if disconnected, replug it. If the issue persists, remove the power cable and check the fuse in the main unit. If the fuse is blown, replace it. If the fuse blows immediately after replacement, the electrical system is faulty.

Why is there high noise in Jasco Measuring Instruments?
- D
  Duane WhitakerSep 5, 2025
  High noise in Jasco Measuring Instruments can occur because the light is not correctly incident upon the center of the entrance slit. If this is the case, you should adjust the light source mirror. Also, high noise may be caused by a spectral bandwidth that is too small, so try increasing the spectral bandwidth. Another reason can be that the absorption of the solvent placed on the reference beam side is too high, in this case replace the solvent with a suitable one. Finally, high noise may appear because the lamp has deteriorated, you should replace it with a new one.
