  For Models 1821 and 1822, connecting the instrument to a computer via a micro USB cable causes an internal temperature rise in the instrument that may result in a temperature measurement error of approximately 2.7°F (1.5°C). This temperature rise does not occur when the instrument is connected to a wall outlet or when it is powered by batteries.
  5.2.1.3. Response Time
  Response time is the time required for e.m.f. to reach 63% of its total variation when the thermocouple is subjected to a temperature step. The sensor’s response time depends on the heat capacity of the medium and the thermal conductivity of the sensor. The response time of a thermocouple with good thermal conductivity, immersed in a medium of high heat capacity, will be short. Conversely, in air or other thermally unfavorable medium, the true response time can be 100 times or more longer than the thermocouple response time.

Model 1823 Temperature Measurements

To determine the total intrinsic uncertainty, add the intrinsic uncertainty of the platinum probe to that of the instrument, shown in the preceding table.

Variation within the Range of Use

Quantity of influence| Range of influence| Quantity influenced| Influence
