Set the flow rate within the rated flow range. The settable rate range is the range of flow rate that can be set in the switch. The rated flow range is the range that satisfies the switch specifications (accuracy, linearity etc.). It is possible to set a value outside of the rated flow range if it is within the settable range, however, the specification is not be guaranteed. The flow range if using CO2 is given in brackets. When using argon (Ar), carbon dioxide (CO2) and the mixed gas (Ar + CO2), refer to page 101.

Analog Output Note) Analog output at maximum rated flow rate when CO2 is selected is 3 [V] for the voltage output type and 12 [mA] for the current output type. Note) When using argon (Ar), carbon dioxide (CO2) and the mixed gas (Ar + CO2), refer to page 101.
