Accuracies assume meter interior has the same temperature of the ambient
(isothermal stage) for a correct junction voltage compensation. Allow enough time to
reach the isothermal stage for a significant change of ambient temperature. It can take
up to an hour for changes > 5°C.

A/mA DC accuracies will be affected by extreme interior temperatures of the meter.
For rated accuracies, allow 6 to 20 minutes cool down interval after measuring A-
currents of 3 to 10A continuously.
