Description
 Measurement value can be calibrated arbitrarily.
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.
Measurement value × [Span set value %]
Output =
For actual keying, refer to the typical operation indicated below. Set the protection to OFF beforehand. (See Section 4.4.1.)
