Warm Up and Environmental Consideration

Operate the 8000 at an ambient temperature in the range of 0 to +40°C. Storage
temperatures should be in the range of -20 to +60°C. To achieve rated accuracy, let
the 8000 warm up for 1 hour. For greatest accuracy, recalibrate when ambient
temperature changes more than a few degrees.
