The accuracy specification does not include
 type D thermocouple probe accuracy.

Temperature Coefficient:  
0.1 times the applicable accuracy specification per 
o
C 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
