„
Display OFF mode
If the [DISP] key is pressed for at least three seconds, only the instan-
taneous flow rate indicator will begin blinking, and the rest of the
display will turn off.
If the
[DISP]
key is pressed in display OFF mode, the instantaneous
flow rate will be displayed.
„
Totalized flow and reverse-totalized flow
If the totalized value exceeds
GGGGGGGG
, the value will be reset to
0
and count will continue to accumulate. In this case, the event output
will be OFF until the count reaches the setting again. The countdown
stops at
0
.
„
Memory backup for totalized flow and reverse-totalized flow
The totalized flow and reverse-totalized flow will be recorded when:
• The totalized flow and reverse-totalized flow are reset.
• 10 minutes have passed after the last time the data was saved.
„
How to reset the totalized flow and reverse-totalized flow
To reset, press the [
▲
] and [
▼
] keys simultaneously for at least one
second while the totalized flow or reverse-totalized flow is displayed.
The totalized flow will be reset to
0
, or the reverse-totalized flow
will be reset to the preset initial value, and counting up or down will
resume.

Event standby
This function is valid only for the instantaneous flow rate low limit. It
prevents a flow rate low limit alarm from faulty operation when there
is no gas flow during device startup.
After the power has been turned ON, unless the instantaneous flow
rate has exceeded the setting for the event low limit, the event is not
triggered. Once the flow rate exceeds the low limit, the event operates
normally.
