Add a temperature coefficient of 0.005% of Range/°C for -10°C to +18°C and +28°C
to +50°C.
Accuracies through four-wire system measurement
For accuracies through three-wire system measurement, add 0.05

. However, this assumes that the resistances of all cables are
the same.
Assume the accuracies through two-wire system measurement to be the same as
those through three-wire system measurement. However, cable resistance are not
taken into consideration.
