Electromagnetic flowmeter M910
Operation manual
45
Datalogger step
DST(?)<CPD> { 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 }
Datalogger can be set:
•
0 Datalogger is Off
•
1 Datalogger sampling rate is 5 minutes.
•
2 Datalogger sampling rate is 10 minutes.
•
3 Datalogger sampling rate is 15 minutes.
•
4 Datalogger sampling rate is 30 minutes.
•
5 Datalogger sampling rate is 45 minutes.
•
6 Datalogger sampling rate is 60 minutes.
•
7 Datalogger sampling rate is 120 minutes.
•
8 Datalogger sampling rate is 180 minutes.
•
9 Datalogger sampling rate is 240 minutes.
M910 confirms datalogger step with string „Ok<cr>”.
Example RS232:
Command „DST0<cr>” switches datalogger “Off”. If query „DST?<cr>” is sent, flowmeter returns response in
format „0<cr>”.
Datalogger number of samples
DNR?
Response contains number of flowrate samples stored in datalogger.
Example:
If query „DNR?<cr>” is sent, flowmeter returns response in format „252<cr>“ for 252 samples in datalogger.
Datalogger filling
DPC?
Response contains datalogger filling in percent.
Example:
If query „DPC?<cr>” is sent, flowmeter returns response in format „14<cr>“ for 14% datalogger full.
Datalogger reading
DRT?
Response contains all values stored in internal datalogger.
Example:
If query „DRT?<cr>” is sent, flowmeter returns response in format:
14:28 13.10.2003 5.820 l/s
14:33 13.10.2003 4.765 l/s
14:38 13.10.2003 4.712 l/s
14:43 13.10.2003 4.792 l/s
14:48 13.10.2003 4.760 l/s
No Record
Datalogger clear
DCLR
Command clears all data stored in internal datalogger.
