,
the lock field changes by a large amount
,
the following message is shown
:
Figure 1.5 Updating the BSMS Field Value in the edlock Table
Pressing OK updates the BSMS field value in the edlock table. A subsequent lock proce-
dure should be able to find the lock signal in the usual way
.
1.13 Manual Shimming to Lineshape
Follow the usual procedure, referring to the Fourier NMR Experiments User Manual
when more information is needed.
Since the shimming process may have an effect on the B0 field, it may be necessary to
redefine BF1 after shimming and lock have been optimized. The ideal BF1 is close to
300.18 when the lock field DAC is close to 2000 (± 500).
1.14 Converting the Parameter Set to the Actual BF1
Before converting the parameter set, make a backup copy of the PAR directory, e.g:
C:\Bruker\TopSpin3.1.b.12\exp\stan\nmr\par
This can be done using CF, followed by “expinstall”. However, the preferred way is to use
CF, followed by the command “paracon”, since it also converts parameter sets in the
user directory. Ignore any error messages when starting, and press “Select all” in both
categories, then execute.
