Specifications
All specifications apply over 0 °C to +55 °C unless otherwise noted and are covered by the product warranty. The
analyzer will meet its specifications when: it’s within the
one year calibration cycle, AUTO ALIGN [ALL] is selected,
stored a minimum 2 hours within the operating temperature range, turned on for at least 5 minutes, and Align Now
RF has been run once every 24 hour period. Typical performance describes the level at which 80% of the units will meet
or exceed with a 95% confidence level over 20 to 30 °C, but is
not covered in the product warranty. Characteristics
describe expected product performance levels that are not
covered in the product warranty.
