<DT>StoreData
|
|
<DD>Does what it says. Writes the current state of the instrument
|
|
including counts to a NeXus data file.
|
|
<DT>count mode preset
|
|
<DD> Does a count operation in mode with a preset of preset.
|
|
The parameters are optional. If they are not
|
|
given the count will be started with the current setting in the histogram
|
|
memory object. After the count, StoreData will be automatically called.
|
|
<DT> Repeat num mode preset.
|
|
<DD> Calls count num times. num is a required parameter. The other two are
|
|
optional and are handled as described above for count.
|
|
<DT> scan motor start step n mode preset
|
|
<DD> This command allows for scanning a motor against monitors 0 and 1. This
|
|
command may only be used by managers. Its only purpose is to facilitate
|
|
the adjustment of the instrument. In order to obtain a copy of the scan
|
|
results, a user must take great care to enable command logging. The
|
|
parameters are: a motor to be scanned, a start value for the scan, a
|
|
step width for the scan, the number of scan points, optionally a count
|
|
mode and a preset value for counting. Both these parameters have meanings
|
|
as described above for the count command.
