Specifications describe the instrument’s warranted performance. Typical and characteristic values
are not warranted, but provide additional information regarding performance that you should
expect from the Model 2820 and are provided to assist in application of the Model 2820.
SpeCiFiCAtionS (warranted performance):
Specifications indicate performance that is warranted. All units are warranted to meet these
performance specifications under the following conditions:
• Ambient operating temperature of 18° to 28°C, unless otherwise noted.
• After a warm-up time of 30 minutes and self calibration at ambient temperature.
typiCAl (mean + 3 standard deviations):
Typical
indicates performance that units will meet under the following conditions:
• Ambient operating temperature of 23°C, unless otherwise noted.
• After a warm-up time of 30 minutes and self calibration at ambient temperature.
This performance is not warranted.
ChArACteriStiC (mean or expected value):
Characteristic
indicates performance that a unit would be expected to exhibit under the
following conditions:
• Ambient operating temperature of 23°C, unless otherwise noted.
• After a warm-up time of 30 minutes and self calibration at ambient temperature.
This performance is not warranted.
