Technical
Temperature scale:  ℃ or ℉ User-Selective.
Resolution: 1℃ or 1℉ (or 0.1℃ or 0.1℉)
                      User-Selective.
Inputs: Two K-type Thermocouples
Measurement Range: -50 ~ 1300℃(-59 ~ 2000℉)
Meter Operating Range: For Using at 0 ~ 50℃
Environment (32 ~ 122℉)
Accuracy: (18 ~ 28℃ ambient)
±(0.3% rdg + 1℃) –50 ~ 1000℃
±(0.5% rdg + 1℃) 1000 ~ 1300℃
±(0.3% rdg + 2℉) -58 ~ 2000℉
The accuracy specification does not include
type K thermocouple probe accuracy.
Temperature Coefficient:  
0.1 times the applicable accuracy specification
per ℃ from 0℃ to 18℃ to 50℃.
Error Offset: Errors contributed by one particular thermocouple may be practically eliminated, over a limited measurement range, using a recessed front panel OFFSET adjust on the meter in an accurate temperature standard when making the adjustment. Although making the adjustment may increase measurement errors for using different thermocouples
Maximum Input: 60V dc or 24V rms ac
between the input pins or any input and ground.
