 SPECIFICATIONS

Technical
Temperature scale:  oC or  oF   User-Selective.
Resolution: 1oC or 1oF (or 0.1oC or 0.1oF) 
                     
User-Selectable
Inputs: One K-type Thermocouple

Measurement Range: -50 ~ 1300oC, (-59 ~ 2000oF)
Meter Operating Range: For Using at  0oC ~ 50o
Environment(32 ~ 122oF)
Accuracy: (18~28
oC ambient)

±(0.3%rdg + 1oC) -50 ~ 1000oC
±(0.5%rdg + 1oC) 1000 ~ 1300oC
±(0.3%rdg + 2oF) -58 ~ 2000oC
The accuracy specification does not include
 type D thermocouple probe accuracy.

Temperature Coefficient:  
0.1 times the applicable accuracy specification per 
oC from 0oC to 18oC  to 50oC
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.
