CP6632
G. T
ECHNICAL SPECIFICATIONS
The indicated levels of precision apply at temperatures of +18°C to +28°C,
unless otherwise specified, and are expressed in ± (n % R + C) where R =
Reading and C = Constant expressed in practical units and given for a
confidence interval of 95%.
They apply to an instrument placed in the reference conditions defined
elsewhere, after fifteen minutes of warming up.
The precision includes the precision of the reference standards, the non-
linearity, the hysteresis, the repeatability and the long-term stability over the
period mentioned.
