Milltronics OCM II PL-269, Instruction Manual

Page: 24 / 107

In addition to the aforementioned totalizers, a serial port totalizer (D22) is provided. It is incremented at the same
rate as D2, but may be viewed or reset by serial communication (refer to Appendix C).
The data logging buffers are configured as ring buffers, capable of storing 45 days of flow information. Following
45 days, further data logs will be stored commencing from the day 1 location again. The OCM II always clears
the next days buffer one day in advance. Therefore a power disruption of less than one day will not leave
previously stored information in that day’s data log location.
TO VIEW THE FLOWRATE LOG:
Enter: [F9] [E]
The OCM II will display a random record which is to be ignored.
Enter: [ddmmyy] [E]
The OCM II will respond with the time 00:00 in the mode window and the corresponding average flowrate of the
previous 15 minute interval will appear in the reading window. Pressing [E] once will step to the next 15 minute
interval or [R] to step backwards. If either [E] or [R] is held, the display will scroll rapidly through the logged data.
If there is no data recorded in the log for the requested date, the reading will indicate error code E9.
TO VIEW A DAILY FLOW TOTAL:
Enter: [F10] [E]
The OCM II will display a random message which is to be ignored.
Enter: [ddmmyy] [E]
The OCM II will respond by showing the date in the mode window and the corresponding day total in the reading
window. Pressing [E] once will step to the next day interval or [R] to step backwards. If either [E] or [R] is held,
the display will scroll rapidly through the logged data.
If there is no data recorded in the log for the requested date, the reading will indicate error code E9.
