You are now ready to confirm that the logger is measuring real data from the sensors
by taking an Instantaneous Value
–
Select the
Current data Values button
to check the instantaneous values the logger
is seeing are as expected -
Radwin will now start reading the current sensor values that the logger is receiving,
so for our example Pressure and Flow logger, we will see -
Click <<Abort>> when you wish to finish
alternatively Radwin will automatically timeout
after a period of a few minutes.
Example Ch1 reading Pressure in Meters Head
and Ch2 reading water Flow in Litres/Sec.
The reading taken is the average over the sampling period specified, so in our
example the last value is 30.16m and 22.0l/s over the last 15m. So if you have just
connected your logger, you may have to wait a few minutes for the reading to
stabilise. The value in the square brackets [301] & [5] is the raw uncorrected value
being measured or counted over 2 seconds.
Note: If the flow readings do not meet your expectations, then check your connections
and your calibration factors have all been entered correctly. If you still have incorrect
readings, you may have a faulty pulse unit on the meter which will need to be
replaced.
