= Test Measurements with Closed Lid

as I was asked already several times how to do these measurements, I put here some information on how to do it

=== goal of such measurements 

record events with closed lid to study what events occur in that case

=== bias on or off
the bias might be switched on of off for these events

bias on: probably muon events (they look different depending on the zd, also the rate changes)[[BR]]
bias off: only electronics noise triggering

= how to do such a measurement

=== sky position

in case you want to do it '''not''' in park position: 

in drivectrl: [[BR]]
''MOVE_TO <zd> <az>''[[BR]]
(you just need to position the telescope, tracking is not needed)[[BR]]
in case you want to go to zenith, I recommend something like 2° as directly zenith might be difficult for a real telescope ;)

=== lid

make sure that the lid is closed

=== configure run

in mcp: [[BR]]
''START <timemax> <nummax> <runtype>''[[BR]]
e.g. ''MCP/START -1 100 data'' (will take a data run of 100 events) 

=== set trigger settings

in ftmctrl: [[BR]]
''STOP_TRIGGER''[[BR]]
''SET_THRESHOLD -1 <threshold>''[[BR]]
e.g. ''SET_THRESHOLD -1 400'' (setting the threshold to 400 DAC counts[[BR]]
''START_TRIGGER''
