Avoid using the NORM_CORR mode because the spectroscopy software will default to
analyzing the LTC spectrum and will ignore the ZDT spectrum.

1.7. DSPEC Pro SMART-1 HPGe Detector Support
ORTEC’s SMART-1 Detector technology is a great advance in the operation of HPGe detectors
and is a major enhancement to data and chain-of-custody integrity. The SMART-1 detector has a
high-voltage supply included, so the DSPEC Pro does not contain a high-voltage power supply.
For older detectors, a detector interface module (DIM) is used to supply the HV for the detector.
The SMART-1 detector monitors and reports on vital system functions. Also, its identification
serial number can be read by a controller such as the DSPEC Pro. For more security it can save
authentication codes written to it and report the code at a later time. The authentication code
value is replaced with every start command. At the end of the acquisition, both the serial number
and code are read and checked with the values at the start of the acquisition.
ORTEC SMART-1 HPGe detectors monitor the following conditions:
