| Item | Description | 
|---|---|
| Ambient temperature | 30°C | 
| Measured value | 100°C | 
| NX Unit | NX-TS2101 | 
| Thermocouple | K thermocouple | 
The characteristic values are formulated from the data sheet or reference accuracy and temperature coefficient table under the above conditions
| Item | Description | 
|---|---|
| Reference accuracy | -100 to 400°C: ±1.5°C | 
| Temperature coefficient | -100 to 400°C: ±0.30°C/°C | 
| Change in the ambient temperature | 25°C -> 30°C 5 deg | 
| Cold junction compensation error | ±1.2°C | 
            Therefore,
Overall accuracy = Reference accuracy + Temperature characteristic x Change in the ambient temperature + Cold junction compensation error
= ±1.5°C + (±0.30°C/°C) x 5 deg + ±1.2°C
= ±4.2°C
						
*5. The ppm value is for the full scale of temperature range.
        
The cold junction compensation error for Units that take a thermocouple input type is restricted as follows according to the installation orientation and the power consumption of adjacent Units *.
| Input type and temperature range | Cold junction compensation error | 
|---|---|
| T below -90°C | ±3.0°C | 
| J, E, K and N below -100°C | |
| U, L and PLII | |
| R and S below 200°C | |
| B below 400°C | Not guaranteed | 
| W | ±3.0°C | 
| Input type and temperature range | Cold junction compensation error | 
|---|---|
| T below -90°C | ±7.0°C | 
| J, E, K and N below -100°C | |
| U, L and PLII | |
| R and S below 200°C | |
| B below 400°C | Not guaranteed | 
| W | ±9.0°C |
