How do I turn on the data logging on my SEI Inspector USB, SEI Inspector Xtreme USB, SEI Inspector EXP or Digilert 200?

You can do this one of two ways. You can turn on the data logging via the Utility Menu on the unit itself. You can access the Utility Menu by holding down the plus button while powering on your detector. Set the date and time first, then turn on the recording feature. You can also turn on the data logging with the Observer USB Software by synching the time and date of your computer and turning on the data logging via the Cal Panel.
