Changing SPs During Operation
Section 3-3
3-3 Changing SPs During Operation
Several channels are grouped together for control when gradient temperature
control is used. Therefore, switch banks and change the SP for all channels if
changing the SP during operation. Uniformity may be adversely affected if the
SP is not changed for all channels in the gradient temperature control groups.
The following example shows using bank switching to change SPs.
a. Change the SP for bank 1 during control using bank 0.
b. Switch to bank 1.
All SP for the group are refreshed when the bank is switched.
When the initial channel of a gradient group is switched, the bank of chan-
nels allocated for that group will be switched. For 2-PID control groups, the
bank can be switched for individual channels in a group.
