Accuracy guaranteed under +23°C±5°C, 20 to 80%RH
Add a temperature coefficient of 0.05°C/°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 1.0°C for Cu10,
0.6°C for Pt50, Pt50G, and Cu50M, and 0.3°C for other RTDs. 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.
Display resolution of source/measured values: 0.1°C
