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 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 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.
What to do if the shorting plug cannot be removed from Bruker 700'54 Ascend Laboratory Equipment?
If you cannot remove the shorting plug 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, using the dipstick or the precooling tube as tubing to remove small ice spots from the connector.
What to do if cooling with liquid nitrogen is too slow on Bruker Laboratory Equipment?
If the cooling with liquid nitrogen is too slow in your Bruker Laboratory Equipment, the transportation dewar may be empty, so refill or replace it. The transfer pressure may be too low; increase it slightly (max. pressure 0.3 bar). The transportation dewar may be leaky, preventing transfer pressure from being applied; check it and replace if necessary.
What to do if the ceiling height is too low for assembling Bruker 700'54 Ascend Laboratory Equipment on magnet stand?
If the ceiling height is too low for assembling your Bruker Laboratory Equipment on the magnet stand because the site does not meet the required conditions, choose another site that meets the required conditions.
What to do if there is high helium flow after breaking vacuum in Bruker 700'54 Ascend Laboratory Equipment?
If there is high helium flow after breaking vacuum in your Bruker Laboratory Equipment, it means that there are remaining cryogenic agents in the vessels. Remove liquid cryogenic agents.
What to do if the current lead cannot be inserted completely into the connector of Bruker 700'54 Ascend Laboratory Equipment?
If the current lead on your Bruker Laboratory Equipment cannot be inserted completely into the connector, it may be due to ice (frozen moisture or nitrogen ice) covering the connector. Carefully remove the ice with warm helium gas, using the dipstick or precooling tube as tubing for the warm helium gas to remove small ice spots. Alternatively, the shorting plug might not have been removed; remove it with the shorting plug tool. Ensure the orientation of the current lead is correct; carefully reposition it until it can be inserted correctly into the connector.
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 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.
