SECTION 16 e. SYSTEM ACCURACY WITH

THERMOCOUPLE INTERFACE

TABLE I

System Accuracy (reading in temperature units): Includes the HHC base unit and XXX interface module.

(Does not include inaccuracy of the thermocouple device. Consult thermocouple manufacturer or ISA MC96.1

for thermocouple accuracy speciﬁcations. Typical inaccuracies range from ±1 to ±2.2°C.)

Conversion Factors (to convert °C speciﬁcations to other units of measure):

To convert from °C to °F: °F = (1.8 x °C) + 32

To convert from °C to °K: °K = °C + 273.15

To convert from °C to °R: °R = (1.8 x °C) + 427.67
