Need help?
Do you have a question about the OPTIMASS 6400 and is the answer not in the manual?
Questions and answers
Hi, do you have a reckomended calibration interval for the 6400F? When to calibrate by manufacturer, or is it maintenanacefree?
The KROHNE OPTIMASS 6400 requires calibration during every proof test or safe configuration. A zero calibration is recommended during these procedures, and factory calibration is used in safe operation. The device is not explicitly stated to be maintenance-free, as it requires periodic proof tests, inspections, and calibrations to ensure proper functioning.
