What to do if flow calibration failed due to plugged outlet in Thermo Scientific Laboratory Equipment?
If the fitting plug was not removed during solvent calibration with the ProFlow flow meter when instructed to do so, remove the fitting plug and repeat the calibration.
Why does Thermo Scientific NCS-3500RS Laboratory Equipment say 'The maximum possible flow for this solvent is (x)'?
If the maximum flow rate for the current solvent has been exceeded, reduce the flow rate.
What to do if the pressure exceeded the absolute limit in Thermo Scientific NCS-3500RS?
If the pressure has exceeded the absolute pressure limit, especially if it builds up extremely fast, first verify that the pressure transducer cables are properly connected on the flow meter.
What to do if a leak is detected in Thermo Scientific Laboratory Equipment?
If a leak is detected, the flow will automatically turn off after 180 seconds. Locate and fix the source of the leak, then dry the leak sensor and tray.
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 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.
What to do if Thermo Scientific NCS-3500RS can't reset pressure sensor because pressure is not constant?
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 flow calibration failed with Implausible measurement results in Thermo Scientific NCS-3500RS 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 the primary pressure exceeded the limit during calibration of Thermo Scientific NCS-3500RS Laboratory Equipment?
If, during solvent calibration with the ProFlow flow meter, the primary pressure exceeded the limit, the flow meter may be clogged.
Why Thermo Scientific NCS-3500RS Laboratory Equipment cannot deliver desired flow at this pressure?
If the internal limit for the primary pressure has been reached, preventing the set flow rate from being delivered, shifts in retention times may be observed during an analysis. Verify that the column pressure is within the normal range. If it is, reduce the flow rate to avoid the problem.
