Temperature Coefficient (or Ambient

Temperature Coefficient (or Ambient Derating)
An indication of the instruments ability to
maintain accuracy when the ambient conditions are subject to a slow change or drift.
The temperature coefficient is usually
expressed as the percent change in accuracy
per degree change in ambient temperature.
For a rapid change in ambient conditions
refer to Thermal Shock.
Temperature Resolution
The minimum simulated or actual change in
target temperature that gives a usable
change in output and/or indication (per the
ASTM standard test method E 1256-88).
