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.
Display resolution of source/measured values: 0.1°C
1 Complies also with JIS C 1602
2 The setting can be changed to comply with IPTS-68 (JIS C 1602 1981).
Accuracy with respect to the measurement or source temperature (t) is
expressed as constant or a linear equation of t.
Example: Accuracy for Thermocouple K (terminal A) measurement value of
1000.0°C = ±(0.5 + (1000.0-500)×0.02%)°C = ±0.6°C
