7.2.2 Measuring Mode Setting
Measuring Modes
The measuring mode is Standard or Noise Reduction mode. Standard mode is set before
shipment. If the output fluctuation is large when a fluid actually flows, the fluctuation is
reduced by increasing the damping time constant.
• If the output fluctuation is still large when the damping time constant is increased, use
the Noise Reduction mode.
• Use the standard mode for sticky fluids.
After the measuring mode is changed from Standard mode to Noise Reduction mode or
from Noise Reduction mode to Standard mode, be sure to adjust the zero point. Perform
zero adjustment with the metering tube filled with the fluid and with the fluid static.
• Standard mode (STD) must be set in case of size 150, 200 mm (6, 8 in).
It cannot be measureed in Noise Reduction mode (FNR).
