Data Logging - oventrop OV-DMC 2 Operating Instructions Manual

Data Logging: Here, several measurements are carried out at different
intervals and are stored in the memory of the flow meter as consecutive valve
numbers.
The data logging function is possible in the balanced pressure method and
when measuring differential pressure. The command "Store" is chosen in the
menu "Store Measurement" and the menu "Store Measurement" is reached by
pressing the key "OK". Apart from "name", "group" and "number", the valve
type, valve size, presetting, differential pressure and the flow rate are stored.
This data can be printed via the serial interface.
"Store" is reached after having confirmed entry by using the key "OK".
Now choose "Data Logging" by using the key
key "OK". The menu window of "Data Logging" is reached next.
Now the clock time in minutes and the number of measurements can be ente-
red. A maximum of 200 measurements is possible with the free storage locati-
ons being indicated in the display under "Measurements". Input has to be
confirmed by using the key "OK". Data logging starts with "Start" and is
confirmed by using the key "OK".
After having processed all measurements, the programme "Data Logging" is
completed automatically.
To conserve the batteries, long term measurements may only be carried out
with the power pack being connected. Should no power supply be available, a
limited number of measurements may be carried out without the power pack.
During entry the following has to be observed:
- The product of clock time and measurements may not exceed 60 (e.g. 10
measurements every 6 minutes).
- The number of measurements may not exceed 20.
- The measurement cycle may not exceed 2 hours.
If the a.m. instructions are not followed, the error message "No powerpack"
appears.
Now a power pack has to be connected and the error message has to be
neutralised by pressing the key "OK". The green control lamp of the flow meter
lights up during power pack operation.
