What to do if shims do not affect the NMR signal on Bruker 700'54 Ascend Laboratory Equipment?
If shims do not affect the NMR signal in your Bruker Laboratory Equipment, it could be because the shim heater current is not correct, and the shim switches are not opened. Set the shim heater current to the specified value.
What to do if Tilt Watch or Shock Watch is activated on Bruker Laboratory Equipment?
If the Tilt Watch or Shock Watch on your Bruker Laboratory Equipment is activated due to careless transportation, accept the delivery with reservation, remark the extent of the damage in the transportation documents, and start a complaint process.
What to do if there is visible damage on Bruker 700'54 Ascend?
If you notice visible damage to your Bruker Laboratory Equipment due to careless transportation, accept the delivery with reservation. Make sure to note the extent of the damage in the transportation documents and initiate a complaint process.
What to do if the Bruker magnet system quenches during de-energizing?
If the helium level is too low for de-energizing your Bruker Laboratory Equipment, refill helium at least to the minimum allowed level. If the power supply is defective or the main current is oscillating, replace the power supply.
What to do if there is audible loss of gas from Bruker Laboratory Equipment?
If you hear an audible loss of gas from your Bruker Laboratory Equipment, the membrane or leveling valve of an isolator may be defective, requiring replacement of the leveling valve or isolator. Alternatively, a hose connector may be defective or loose; insert hoses correctly and tighten screws.
What to do if the transfer of liquid helium does not start in Bruker 700'54 Ascend?
If the transfer of liquid helium does not start in your Bruker Laboratory Equipment, it could be because the transportation dewar is empty; refill or replace it. The transfer pressure in the transportation dewar may be too low; increase the transfer pressure. The transportation dewar might be leaky, preventing transfer pressure from building up; check it for leakage and re-tighten all connections. The siphon or helium transfer line could be blocked with ice; check for blockages and remove ice with warm helium gas.
What to do if the magnet system does not reach specification on Bruker 700'54 Ascend?
If the magnet system does not reach specification in your Bruker Laboratory Equipment, it could be due to magnetic material inside the RT bore tube; carefully clean the RT bore tube. Large ferromagnetic parts near the magnet system can also cause this; keep all ferromagnetic parts away from the magnet system as much as possible and repeat shimming.
What to do if the shim current cannot be set correctly on Bruker 700'54 Ascend?
If the shim current cannot be set correctly on your Bruker Laboratory Equipment, ensure the control cable is correctly connected to the current lead and to the power supply. Also, check that the switch "Main Coil/OFF/Shim Coil" is in the correct position.
What to do if the current lead cannot be removed from Bruker Laboratory Equipment?
If you cannot remove the current lead from your Bruker Laboratory Equipment, it is likely that the connector is covered with ice (frozen moisture or nitrogen ice). Carefully remove the ice with warm helium gas over the helium flow system, using the dipstick or the precooling tube as tubing to remove small ice spots from the connector.
What to do if the helium boil off is too high in Bruker Laboratory Equipment?
If the helium boil off is too high in your Bruker Laboratory Equipment, it could be because the Helium Level Sensor is in service mode or has been used too often; switch off the Helium Level Sensor and reduce the frequency of helium level measurement. The atmospheric pressure might be decreasing, which is usual behavior, so check the helium boil off daily. Reduced vacuum can also cause this; rebuild the vacuum. Additionally, the radiation baffles might not be inserted in the current lead turret; insert the radiation baffles into the current lead turret.
