*1 Unit pulse: A flow rate pulse after the unit matching by an arithmetic circuit
High-density pulse: A flow rate pulse that is output in synchronization with the rotation of the impeller
Duty ratio: 0.45 to 0.55 (at a constant flow rate)
*2 The OFF resistant is 100 k

or more.
*3 The maximum frequency with the standard specifications. The maximum frequency varies with the
pulse output unit that has been set.
Note that the maximum frequency will be approximately 8 Hz when the pulse output unit of TBX30 (D)
is set to 1 L/P.
