Thanks Mark, that worked very well! 

Thank you very much, I am now able to talk to a
dBmeter from Brüel & Kjær, via USB and Python.

Sample Code if anyone else needs to do this task (on
the 2250 model):

import win32com.client
q =
win32com.client.Dispatch("BK.BasicEnv.Application.RemoteAPI")
Instrument = win32com.client.CastTo(q,
'I2250Instrument')
Connect = win32com.client.CastTo(q, 'I2250Connect')
Control = win32com.client.CastTo(q, 'I2250Control')
instrumentNames=Connect.GetInstrumentNames()
Connect.Connect (instrumentNames[0])
db=Control.ReadOutputInt16(instrumentNames[0],
"LACF(SPL)")
print "dBA value %.1f\n" % (db/100.0)
q.Disconnect()

Best regards
Mikael
