possible cause
The measured flow rate
has stayed under the
minimum threshold for
the set time delay.
This message appears
when the flow rate
is monitored (see
chap. 8.7.4).
The measured flow rate
has stayed above the
maximum threshold for
the set time delay.
This message appears
when the flow rate
is monitored (see
chap. 8.7.4).
The real flow rate cannot
be displayed (display has
reached its max. possible
value).
Except the display,
the device operates
depending on the real
flow rate.
Calibration of the current
output is lost.
The device generates
unprecise intensities
on the analogue output
AO1.
The daily totalizer has
reached the value set in
parameter "VOLUME-
W." of the Test menu.
