How to achieve zero absorbance when calibrating jenway 7305 Measuring Instruments?
- D
  Dakota OlsonAug 17, 2025
  To address the issue of not achieving zero absorbance or 100% transmittance during calibration with your Jenway Measuring Instruments, first, verify that there is no sample present in the sample chamber. Next, ensure the instrument lid is properly closed before and during the calibration process. Finally, check if the lamp is functioning correctly; if it has failed, replace the lamp (7300) or the lamp module (7305).

  If you're unable to get a reading when measuring a sample using your Jenway Measuring Instruments, start by ensuring that you're using the correct cuvette, one that doesn't absorb the light. Also, check that the sample isn't too dense, preventing light from transmitting through it. Finally, verify that the lamp is working properly.

Why does my Jenway Measuring Instruments show 'Err 5 - Light Saturation Not Found'?
- J
  Jennifer PayneAug 22, 2025
  If your Jenway Measuring Instruments display an 'Err 5 - Light Saturation Not Found' error, it could be due to a lamp failure, a deteriorating lamp signal, or a sample/cuvette being present in the sample holder. First, ensure the sample holder is empty. Then, restart the unit. If the problem persists, contact a service technician.
