What to do if GE Novaspec Plus Measuring Instruments shows a flashing Absorbance reading of 2.00 Abs?
- TTheresa LawsonAug 18, 2025
If you observe a flashing Absorbance reading of 2.00 Abs, it indicates that the sample needs to be diluted.
What to do if GE Novaspec Plus Measuring Instruments shows a flashing Absorbance reading of 2.00 Abs?
If you observe a flashing Absorbance reading of 2.00 Abs, it indicates that the sample needs to be diluted.
What to do if GE Novaspec Plus Measuring Instruments shows Error code 001 symbol?
If Error code 001 appears, it means the lamp needs changing.
Why does GE Measuring Instruments switch off after calibration?
The instrument may be switching off after calibration because the ON/OFF button is being held for too long. This can cause the instrument to receive both ON and OFF signals. Try adjusting the timing of your finger press at switch on.
How to fix GE Novaspec Plus Measuring Instruments failing start up calibration check?
If the instrument fails the start up calibration check, ensure that the sample and reference beams are clear when the instrument is switched on.
What to do if GE Novaspec Plus shows X against Lamp on initialisation screen?
If an 'X' appears against the lamp on the initialization screen, it indicates that the lamp needs to be replaced.
What to do if GE Novaspec Plus shows Absorbance readings unstable?
If you are experiencing unstable absorbance readings, ensure that Reference QA is switched on, background correction is enabled, and that a 2 µl sample is being used.
Why does GE Novaspec Plus show a negative reading?
Negative readings can occur if the Reference and Test cuvettes are mixed up.
What to do if GE Measuring Instruments instrument will not zero?
The instrument may not zero if the cuvette is placed in the wrong orientation or if the wrong cuvette material is used for the wavelength.
What to do if GE Measuring Instruments shows REF is displayed when T is pressed?
If 'REF' is displayed when 'T' is pressed, it means the instrument was not zeroed before a sample measurement was attempted.
What to do if GE Measuring Instruments gives Poor reproducibility on DNA concentration and purity measurements?
Poor reproducibility in DNA concentration and purity measurements can occur if the wrong cuvette is used (not a 15 mm beam height or wrong material not letting UV light pass through), if background correction mode is not switched on, or if the measured absorbance is too low (should be >0.1 A for accurate results).
