When turning on the personalDataRAM after resetting the instrument, it should be
zeroed (see steps 1 and 2 of Section 8.1) before a run is initiated. Otherwise, its
internal optical background level will not be subtracted from the indicated
concentration readings. Alternatively, if the instrument is not zeroed after resetting,
it will indicate its unsubtracted optical background when run under particle free
conditions.

Hardware and Software Requirements
The computer requirements to install the software provided with the
personalDataRAM (Thermo Scientific pDR-COM) are the following:
• IBM-PC compatible
• 486, Pentium, or better processor
• Minimum operating system: Windows 95™ or better
• ≥ 8 MB of RAM
• 2 MB of hard drive space
• CD-ROM drive
• VGA or higher resolution monitor
NOTE: When large files are logged in the personalDataRAM in one single tag, a
faster computer speed is required to handle the data. For example, if all
13,000 data points are logged in one tag, a Pentium I or II processor with a
minimum speed of 166 MHz will be required. If, however, the maximum
number of data points per tag is 1,000 or below, a 33 MHz, 486 DX
processor will suffice.
Thermo Fisher Scientific custom hardware and software (provided as standard
accessories):
• Digital communications cable (model pDR-DCC)
• CD-ROM disk
