DE-305温度表(温度计)（K型探头）

Technical
Temperature scale:  ^oC or  ^oF   User-Selective.
Resolution: 1^oC or 1^oF (or 0.1^oC or 0.1^oF) 
                      User-Selectable
Inputs: One K-type Thermocouple
Measurement Range: -50 ~ 1300^oC, (-59 ~ 2000^oF)
Meter Operating Range: For Using at  0^oC ~ 50^oC 
Environment(32 ~ 122^oF)
Accuracy: (18~28^oC ambient)
±(0.3%rdg + 1^oC)-50 ~ 1000^oC
±(0.5%rdg + 1^oC)1000 ~ 1300^oC
±(0.3%rdg + 2^oF)-58 ~ 2000^oC
The accuracy specification does not include
 type D thermocouple probe accuracy.
Temperature Coefficient:  
0.1 times the applicable accuracy specification per 
^oC from 0^oC to 18^oC  to 50^oC
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 and an accurate temperature standard when making the adjustment. Although making the adjustment may increase measurement errors for using different themocouples
Maximum Input: 60V dc or 24V rms ac 
between the input pins or any input and ground.
