Troubleshooting

Table continued 

Indicator

Possible reason

Solution

Performed by

Shim current can 
not be set correctly.

The control cable is 
not connected 
correctly to the 
current lead or to 
the power supply.

Connect the control cable 
correctly to the current lead 
and to the power supply.

Bruker Service

The switch „Main 
Coil/OFF/Shim 
Coil“ is in the wrong 
position.

Change the switch position.

Bruker Service

Shims do not affect 
the NMR signal.

Shim heater 
current is not 
correct. The shim 
switches are not 
opened.

Set the shim heater current 
to the specified value 
(see 

Energizing Assign-

ment and Currents on 
page 81

).

Bruker Service

Magnet system 
does not reach 
specification.

Magnetic material 
inside RT bore 
tube.

Carefully clean the RT bore 
tube.

Bruker Service

Large ferromag-
netic parts near the 
magnet system.

1.

As much as possible,

keep all ferromagnetic

parts away from the

magnet system.

2.

Repeat shimming.
