Technical Specifications:
The instrument should operate continuously for more than 30 minutes under the specified operating temperature.
If the operating temperature is up to or larger than 41°F / 5°C, the system function menu must be opened to make the system perform a “Auto- calibration” procedure.
Except those specifications marked with the word Typical, all specifications can be up to the mentioned definitions.
