1
Specifications given are percent of full scale, ±10 V (that is, 0.01% = 1 mV).
2
Tested on all production units at final electrical test. Results from those tests are used to calculate outgoing quality levels.
3
Can be reduced down to 3 V using external resistor between –V
S
and SF.
4
Irreducible component due to nonlinearity; excludes effect of offsets.
5
Using external resistor adjusted to give SF = 3 V.
