NFA Series Key Specifications
Specifications apply over 0°C to +55°C unless otherwise noted. The
analyzer will meet its specifications after 2 hours of storage within
the operating temperature range, 60 minutes after the analyzer is
turned on, with Alignment running. A user calibration is required
before corrected measurements can be made.
