Why does the level reading fluctuate strongly on my BERTHOLD TECHNOLOGIES LB 480?
M
Michael ArnoldAug 3, 2025
Strong fluctuations in the level reading of your BERTHOLD TECHNOLOGIES Measuring Instruments can occur due to several reasons:
* The time constant might be too small. You should increase the time constant in the Parameter menu (min. 20s).
* The calibration could be wrong. Check your calibration values.
* Rapid switchover with too small Sigma value. Increase the Sigma value or disable automatic time switch.
* Count rate too low. Check age of source and irradiation level; replace detector.

What to do if the count rate is too low on BERTHOLD TECHNOLOGIES Measuring Instruments?

If the count rate is too low on your BERTHOLD TECHNOLOGIES Measuring Instruments, consider the following possible causes and solutions:
* The shielding may not be open or not open correctly. Check the lock and secure it in the OPEN position.
* The alignment of the effective radiation towards the detector may be incorrect. Correct and optimize the alignment.
* Container installations may be in the beam path. Offset the irradiation plane.
* Wall deposits may be present in the container. Remove wall deposits or perform a new calibration if the wall deposits cannot be removed.
* The source may have reached the end of its service life. Replace the source.
Drifting level readings on your BERTHOLD TECHNOLOGIES Measuring Instruments can be attributed to:
* A faulty detector stabilization. Replace the detector.
* A faulty multiplier. Exchange the multiplier.

What to do if current output at 24mA on BERTHOLD TECHNOLOGIES LB 480?

Tracey ThomasAug 27, 2025
If the current output is at 24mA on your BERTHOLD TECHNOLOGIES Measuring Instruments, this could indicate that the current output is faulty or defective. Recalibrate the current output. Then restart the detector by Software Reset or by turning the power supply off/on. If the current output cannot be calibrated, the detector needs to be repaired.
