Temperature ranges (°C / °F)
1)
Add the measuring accuracy of the wire temperature sensor (type K) to the specified
measuring accuracy.
• Measuring range: -20 ... 200 °C (-4 ... 392 °F)
• Measuring accuracy: ±1.5 °C (±1.8 °F)
2)
The measuring accuracy applies to stable ambient temperatures lower than ±1° C. After
a change of the ambient temperature of ±2 °C, the measuring accuracy specifications
will apply after 2 hours.
