If your EUTECH INSTRUMENTS Measuring Instruments displays a low battery indication, replace the batteries.
How to fix low battery indication on EUTECH INSTRUMENTS Measuring Instruments?
If your EUTECH INSTRUMENTS Measuring Instruments displays a low battery indication, replace the batteries.
What to do if EUTECH INSTRUMENTS Measuring Instruments shows *ERR1 error?
If your EUTECH INSTRUMENTS Measuring Instruments shows '*ERR1' error, it indicates a calibration failure. This can occur if the absorbance of the calibration standard is outside the acceptable range for the selected calibration point. To resolve this, make sure your calibration standard is accurately prepared. If the issue persists, replace the calibration standard with one of a known accurate value and recalibrate the device.
What to do if EUTECH INSTRUMENTS Measuring Instruments shows *ERR0 error?
If your EUTECH INSTRUMENTS Measuring Instruments displays '*ERR0' error, it means there's an inappropriate signal recognizing the blank, or the sample absorbance is less than blanking. Ensure that blanking is done before adding the chemical reagent and repeat the blanking procedure.
What causes *ERR2 error on EUTECH INSTRUMENTS Measuring Instruments?
If your EUTECH INSTRUMENTS Measuring Instruments displays '*ERR2' error, it indicates excessive stray light was detected. Make sure the vial is fully snapped into the sample well.
What does *ERR3 error mean on EUTECH INSTRUMENTS Measuring Instruments?
If your EUTECH INSTRUMENTS Measuring Instruments displays '*ERR3' error, it indicates a lamp failure, meaning the LED is faulty. Return the unit for repair.
How to fix OR error on EUTECH INSTRUMENTS Measuring Instruments?
To resolve the 'OR' error on your EUTECH INSTRUMENTS Measuring Instruments, ensure the sample value is within the measurement range specified in the Specification table in Section 7.
How to resolve UR error on EUTECH INSTRUMENTS Measuring Instruments?
To resolve the 'UR' error on your EUTECH INSTRUMENTS Measuring Instruments, ensure the sample value is within the measurement range specified in the Specification table in Section 7.
