Description
● Measured value can be calibrated manually.
Zero point and span adjustment can be made.
Settable range
(1)
Zero point
: -5 to +5 [m/s] in terms of flow velocity
in piping.
(2)
Span
: ±200%
The output value (reading, analog output and total output)
is computed by the following expression.
Measured value × [Span set value %]
Output =
<Note> The flow rate unit is the unit selected at "VOLUME FLOW UNIT".
Specify the "VOLUME FLOW UNIT" setting before setting. (See Section 4.7.2)
For actual keying, refer to the typical operation indicated below. Set the protection to OFF beforehand. (See Section 4.4.1.)
Operation
Compensate the zero point to 0.5m3/h, and the span by +1%.
(example)
* Set the PIPE PARAMETER and VOLUME FLOW UNIT beforehand.
