〔Exp. Value〕
The magnification per 1 pulse is decided at registered property of
“Mode No.1” and “Exp. value”.
〔Moving average range〕
Set the number of pulses to be averaged. For example, when 04 is
set, four pulses are read, calculated, averaged, and indicated.
This function is effective in the case that the flow rate value per pulse
is not exact. For this calculation, however, the latest one pulse is
taken in and the preceding pulse is discharged, and four pulses are read,
moving-averaged, and indicated.
This function should be applied only at 20 Hz or less.
〔Ex.〕
Signal output
Detecting block Input pulse
First time
Moving Second time
Flow average range Third time
For example, if fitting angles four blades of the impeller are uneven,
the indication is unstable even if the flow rate is constant, but setting 4
for moving average offers average values calculated taking the latest
pulses in. And as seen in the above figure, the calculation is made
every time when a pulse comes in, but the indicated time becomes that
set according to “the setting of the sampling time” of “Mode No.6”.
《Relationship between the moving average range and sampling time》
The newest data, obtained from the moving average performed at
the preset sampling interval, is indicated in the reading if sampling
is specified.
〔Auto-zero time〕
If no input signal comes in within the set time, this function returns
the reading indication value to "0".
