Why flow calibration failed with Implausible measurement results in Thermo Scientific Dionex UltiMate 3000 Laboratory Equipment?
If flow calibration of the ProFlow flow meter yields implausible measurement results, a mismatch between the solvent and the sensor selected for calibration was detected. Repeat the flow calibration with the correct solvent or change the solvent. Contact Service.
Why Thermo Scientific Security Sensors analysis run takes long time?
If your Thermo Scientific Security Sensors analysis run takes a long time to start, check the set flow cell temperature. If the flow cell can't reach the desired temperature at high flow rates, select a lower temperature.
What to do if Thermo Scientific Laboratory Equipment can't reset pressure sensor because pressure is out of range?
If the pump pressure is not down to zero during the self test, wait until the pressure is down and repeat the test. Verify that the cable for the system pressure transducer is properly connected to the P-Sys connector for the loading pump on the interior front panel. Open and close the purge valve if necessary to reduce the pressure.
Why all flows need to be stopped before servicing the pistons in Thermo Scientific Laboratory Equipment?
If you attempt to move the pistons of the loading pump into the position for piston or piston seal replacement before the flow rate is down to zero, set the pump flow rate to 0 and wait until the system pressure is down to zero.
What to do if Thermo Scientific Dionex UltiMate 3000 Laboratory Equipment says 'Can't do this when the flow is on'?
If you attempt to perform a self test for the pump before the flow rate is down to zero, set the pump flow rate to 0 and repeat the command.
What to do if Thermo Scientific Security Sensors says 'command rejected'?
If you encounter a 'command rejected - device is busy' error on your Thermo Scientific Security Sensors, wait until the detector has executed the active command and retry.
How to reduce backpressure in Thermo Scientific Security Sensors?
If your Thermo Scientific Security Sensors system has very high backpressure, check the capillaries from the detector to the pump, step by step. Remove any blockages or replace the capillaries as needed.
How to resolve periodic baseline fluctuation, pulsation in Thermo Scientific Dionex UltiMate 3000?
Periodic baseline fluctuation and pulsation can occur due to pressure fluctuations from the pump or air bubbles in the system. Purge the pump to resolve this issue.
What to do if Thermo Scientific Dionex UltiMate 3000 displays 'Flow meter missing'?
If communication with the flow meter failed, verify that the flow meter is installed properly.
What to do if Thermo Scientific Laboratory Equipment displays 'Flow selector missing'?
If the flow selector in the Classic flow meter may not be installed or the installation may not be correct, verify that the flow selector is installed properly.
