+ !The needle valve control is unstable
+ * If you are in automatic mode, switch to controlled mode, and
+ select the flow by hand (a good flow value is selected when the
+ heater power at 10 K (stable) is about 0.15 W.
+ * If you are in controlled mode, you might need to increase the "flow int"
+ value (to 10 or even 100 sec) and change the pulse length.
+ * You might also consider to work in fixed mode (after having found
+ a reasonable needle valve motor position) when not changing

+ !Restarting SEA
+ Restarting the SEA client is sometimes a good idea when problems
+ arise. Restarting the SEA server is rarely necessary, but might also
+ help. From the instrument account enter
+ {{{
+ monit restart sea
+ }}}
+ to restart the SEA server. Normally, restarting the SEA server does
+ not harm the instrument program. However, when the SICS server is in
+ Driving mode, the objects linked to SEA may be lost. In this case
+ just enter
+ {{{
+ connect_sea
+ }}}
+ on the SICS prompt.
