7.3 Basic operations
7.3.1 Mode Change
The converter provides the setting mode and calibration mode, in addition to the measurement mode.
When you want to move to the setting mode or calibration mode, use the "SET" key. To return to the
measurement mode, select "MEAS MODE" from menu items (A to N).
Measurement mode:
measures the process flow and displays and outputs the measured process values. The
flowmeter can measure the flow velocity, flow rates, or totalized flow. The flowmeter first goes
into this mode when power is turned on.
Setting mode:
used to check or change various configuration parameters used in the measurement mode.
These parameter values are displayed while checking or changing these values but the flowmeter
outputs the measured process values as in the measurement mode. See 7.4, “Configuration Items
Selection Table” and 8.2, “Checking or Changing Parameters” for details.
Configuration items are from Al, A2, A3 to Ml.
Calibration mode:
used to check the converter internal circuits. The internally generated simulation signal is used
to check the measuring span and excitation current value. The current output of the
flowmeter changes in accordance with the simulation signal. The status of each digital output is
held to the value just before the system moved into the calibration mode.
See 7.4, “Configuration Items Selection Table” and Chapter 9, “Calibration” for details.
Configuration items are from N1 to N4.
