(Note) Data are output in the order of density (data converted into that at a reference
temperature), density (at measuring temperature), and measuring liquid temperature.
Hold data (data immediately before entering the mode) is output during the time of
calibration or maintenance mode. However, holding is released immediately after
calibration or maintenance mode.

Fault detecting contents: Detector failure and converter failure
Failure output:
Analog signal: Falls down to about –10 % of the output signal span
Digital signal: Error message outputs
Output signal hold: Holds in the CAL. or Maintenance mode.
Settable range for temperature coeffi cient: 0 to 0.002 g/cm 3 /°C
Calibration procedure: One-touch calibration by strong calibration liquid density
(onepoint calibration)
