    Setup of the instrument is accomplished through the front-panel buttons, or through Lumic 2 software available from Ludlum Measurements. Front-panel setup can be disabled via the internal switch on the Model 3002 in order to pro- tect settings from inadvertent changes. When the settings are protected, the user can view the settings or modify a limited number of settings as defined with the Lumic software.
  • Page 18 The unit can log up to 1000 alpha and beta measurements simultaneously, and it adds a date/time stamp to each measurement. There are several options for the Model 3002 , including a headphone jack (for listening to clicks in noisy environments), a storage or shipping case to securely transport or store your instrument, and an optional set of rings to fasten a shoulder strap to the instrument for easier carrying.
