Zero-point adjustment function
● The zero-point adjustment function is used to adjust the gap of the zero-point be-
tween the display and the analogue voltage output.

Flow direction setting
● Sets the flow direction of fluid. Either bi-direction, one-side forward direction or
one-side reverse direction can be set. (Factory setting: bi-direction)
● When setting flow direction to bi-direction or one-side forward direction, if fluid
flows in the direction opposite to the forward direction display on the main body,
the flow rate value is indicated negatively. In case of one-side reverse direction, if
the fluid flows in the same direction to the forward direction display, the flow rate
value is indicated negatively.
● Zero-point and the span of the analogue voltage output change as follows de-
pending on the set flow direction.

CH2 setting
● Select whether CH2 is used as comparative output 2, integrated value reset input
function or teaching function. (Factory setting: comparative output 2)
● When setting CH2 to the teaching function, select method for loading input value,
the number of input points and input waveform operation.

Response time setting
● Sets response time. The response time can be selected from seven levels: 50 to
1,500ms. Chattering and malfunction due to rapid change in the flow rate can be
prevented. (Factory setting: 50ms)
