Electrical Specifications
Accuracy is given as ± (% of reading + counts of least significant
digit) at 23°C ± 5°C, with relative humidity Less than 80% R.H.,
and is specified for 1 year after calibration.
(1) Temperature coefficient
0.1 x (Specified accuracy) / °C, < 18°C, > 28°C
(2) AC Function
ACV and ACA specifications are ac coupled, true R.M.S.
