What to do if unable to achieve a reading when measuring a sample with jenway 6850?
If you are unable to achieve a reading when measuring a sample with your Jenway Measuring Instruments, make sure you are using the correct cuvettes, so that light isn’t being absorbed by the cuvette. Also, make sure the sample isn’t too dense, preventing light from transmitting through it. Finally, verify that the lamp is working.
