Further errors and countermeasures
(1) When the device indicates 0.0000 even though there is a volume flow
and an “R“ glows in
the display and the signal quality Q is ok, there must be a different error. In many cases, this
means that the zero point has been set incorrectly. Go to menu M432 and reset the zero
point.
(2) The displayed volume flow is obviously too low or too high:
a) Probably, the volume flow in window M44 has been entered manually. Set this value to
“0“.
b) Problems with the sensor installation
c) Possibly, the display was set to “0“ via M42 despite an existing volume flow. Repeat the
zero point setting and make sure that there is no flow in the pipe.
(3) The real battery life is shorter than the value stated in M07.
a) The battery has exceeded its life cycle.
b) The battery has not been charged completely or the charging procedure has been
interrupted too frequently. Charge the battery again. If the problem persists, contact PCE
Instruments.
c) When the battery voltage is between 3.70 and 3.90 V, discrepancies between the
estimated and the actual transit time can occur.
