Try pressing the Enter key then 911 then CE to clear the error and try another run. If problems persist after this then service will be required. I hope this helps.

We have J-25 old centrifuge but it doesnt have ENTER key. How can I clear S7 error in this case?A:To clear an S7 on a J25; press Time, Accel, CE. All your calibration factors were set to Default (100) and the elevation is set to 0 meters by the S7. This is when RAM Memory doesnt agree with other parameters. Bad power can sometimes cause this. The latest version of Firmware does not reset the calibration factors to default. You may want to have the Beckman technician bring the latest firmware and calibrate your instrument. If you prefer, I can email you the procedure to calibrate the instrument yourself.Q: Thank you for your proposition, but I do not have the button CE, so I cant do this.I have only these buttons: Accel, Decel, Clear, RPM/RCF, Time/Hold, Start, Stop, Set/Actual.A:The CE (Clear Entry) and the Clear button are the same thing.Q: I have tried to do this, but nothing happened. I have also changed the BBRAMs in tower of centrifuge - nothing. Is it the last chance to replace electronic board in tower?A:On the J25 series, you must enter a pre-code sequence to enter the repair code. I assumed that you had this pre-code. Sorry. Here is the full sequence of keys that must be pressed to clear an S7. Set-Accel-Set-Decel-Time-Accel-Clear. Disregard the hyphens. I put those in as separators in this text. Q: I have tried to put this code Set-Accel-Set-Decel-Time-Accel-Clear and
