- CCheryl OlsenAug 31, 2025
Restart the device. If the event occurs frequently, contact Berthold.
What to do if the voltage of the control channel deviates from the admissible set value in Berthold Security Sensors?
Restart the device. If the event occurs frequently, contact Berthold.
Why is there no count rate in the auxiliary channel of my Berthold LB 4700 Measuring Instruments?
If there is no count rate in the auxiliary channel of your Berthold Measuring Instruments, the photomultiplier may be defective. Check the photomultiplier or contact BERTHOLD.
What to do if Berthold Security Sensors has an error when reading the Pt100 input?
Restart the device. If the event occurs frequently, contact Berthold. The event must be confirmed manually.
What to do for a permanent memory error in Berthold LB 4700?
If a permanent memory error occurs and no parameter set was found in your Berthold Measuring Instruments, perform a factory reset and/or restart the device. If the event occurs frequently, contact BERTHOLD.
What to do if the average HV exceeds the Default-HV by more than 40% in Berthold Measuring Instruments?
If the average HV exceeds the Default-HV by more than 40% in your Berthold Measuring Instruments, check the Default HV for plausibility and change if necessary. Also, check the detector electronics and photomultiplier. If necessary, contact BERTHOLD.
What to do if the count rate fluctuates more than permissible in Berthold LB 4700 Measuring Instruments?
If the count rate fluctuates more than permissible in your Berthold Measuring Instruments, and the event occurs frequently, contact BERTHOLD.
How to fix a corrupted HW module in Berthold LB 4700?
If the HW module is corrupted in your Berthold Measuring Instruments, restart the device. If the event occurs frequently, contact BERTHOLD.
What to do if Berthold Security Sensors shows a permanent memory error?
Perform a factory reset and/or restart the device. If the event occurs frequently, contact Berthold.
What to do if Berthold Security Sensors detected an error in the high-voltage supply of the photomultiplier?
Check detector electronics and photomultiplier. If necessary, contact Berthold.
What to do if the Berthold Security Sensors detector temperature is too high or too low?
If the detector is too hot: Install/check water cooling system. If the detector is too cold: Install/check heating.
