What to do if the display is unreadable on Berthold Measuring Instruments?
If the Berthold Measuring Instruments display is unreadable, it might be due to a processor error. Note the error code. Another cause may require you to perform a total reset or replace the evaluation unit.
Why is the result reading fluctuating strongly on Berthold Measuring Instruments?
If your Berthold Measuring Instruments show a result reading that fluctuates strongly, the time constant might be too small. Increase the time constant in the Measuring Parameter menu to a minimum of 20 seconds. Also, check the age of the source and irradiation level, and consider replacing the detector if the pulse rate is too low.
Why does the result reading show drifts on Berthold Measuring Instruments?
If your Berthold Measuring Instruments show drifts in the result reading, it could be due to a faulty detector stabilization. In this case, replace the detector. Another possible cause is a faulty photomultiplier, which would also need replacement.
How to troubleshoot no display on Berthold Measuring Instruments?
If the Berthold Measuring Instruments have no display, the issue might be due to no power supply. Check the mains cables. Also, check the fuses.
What to do if the pulse rate is too low on Berthold Measuring Instruments?
If the pulse rate is too low on Berthold Measuring Instruments, ensure the shielding is fully open and properly secured in the OPEN position. Also, check and correct the alignment of the useful beam toward the detector. If the source has reached the end of its service life, renew the source (Co-60 after 5 to 10 years, at the earliest).
What to do if Berthold Measuring Instruments show no pulse rate (Error code 2)?
If you are getting no pulse rate (Error code 2) on your Berthold Measuring Instruments, the power supply to the detector might be interrupted. Check the cable to the detector. If the cable is fine, the detector might be faulty, and you should replace it.
Why is the output current incorrect on Berthold Measuring Instruments?
If the output current is incorrect on Berthold Measuring Instruments, verify the calibration values are entered correctly.
Why is the result reading no or incorrect on Berthold Measuring Instruments?
If the result reading is no or incorrect on Berthold Measuring Instruments, ensure that the calibration values are entered correctly.
