■ Characteristics
Note: 1. The indication accuracy of the K1, T, and N thermocouples at a temperature of 100qC or less is r2qC r1 digit maximum. The indication
accuracy of the U, L1, and L2 thermocouples at any temperature is r2qC r1 digit maximum.
The indication accuracy of the B thermocouple at a temperature of 400qC or less is unrestricted.
The indication accuracy of the R and S thermocouples at a temperature of 200qC or less is r3qC r1 digit maximum.
The indication accuracy of the W thermocouple at any temperature is (r0.3% of the indicated value or r3qC, whichever is greater) r1digit
