）
ｎ＝0 - 9
ＦＧ→Moving average range
00 - 19（pulses） ※00 and 01 are equivalent in effect.
Ｈ→Auto-zero time
０：disables the function ５：10 sec.
１：0.5 sec. ６：20 sec.
２：1 sec. ７：30 sec.
３：2 sec. ８：60 sec.
４：5 sec. ９：120 sec.
〔ＦＧ：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 lower.
〔Ｈ：Auto-zero time〕
If no input signal comes in within the set time, this function returns the reading indication
value to
“
0
”
.
Please note that when 0 is specified, this function is disabled, and the reading remains
still even after the input is shut off.
