5.10.4 THE DATALOGGER CONTROL MENU
The [Datalogger Control] menu in the Channel Setup menu provides the Datalogger controls for the
meter’s measurement channels. It allows you to enable usage, select data items/alarm events, a log-
ging interval and a destination for your Datalogger reports. While the [Datalogger Control] menu is mea-
surement channel specific, this menu provides global control functions. This means that the settings
made here apply to all measurement channels, meter types, operating modes, etc. This is possible
because the meter stores logged data in a
single file . This is significant for dual-channel systems, since
the logged data from both channels are combined. Therefore, select the Site ID item for each channel to
be logged.
The [Datalogger Control] menu allows you to select a [Circular Memory] mode that will over-write the
oldest Datalogger data automatically when the Datalogger memory becomes full due to the data com-
pression scheme employed.
Note that this is only available for dual-channel systems.
The [Est Log Time Left] view-only menu cell shows an estimate of the hours and minutes of logging time
remaining. This only applies to non-circular datalogging. Selecting [Circular Memory] blanks this field.
The [Output Datalogger] command sends data to an external device via the RS-232 serial port. Data
transmitted from this menu will be from both channels of a dual-channel system.
The [Clear Datalogger] command erases the entire Datalogger file. For dual-channel systems, you are
cautioned not to use this command if your intention is to clear the logged data of only one channel.
To access the [Datalogger Control] menu press
Output Datalogger
This menu cell allows you to send the Datalogger contents to an external device (usually a computer or
printer) via the meter’s RS-232 Serial I/O port. This command is effective only after a successful install. In
addition, you have to enable datalogging and select data items in the [Datalogger Control] menu.
Note:
This command sends the data collected by both channels of a dual-channel system. Therefore,
you should include [Site ID] (current site setup name), [Date] and [Time] in your report so that you can
identify the source of each report.
The FUH1010PVX meter interfaces with most serial printers or personal computers. Siemens offers the
Model 996P portable serial printer. You must use the proper cabling between the flow computer and the
external device. In addition, you must configure the [RS-232 Setup] menu cell correctly (see paragraph
5.10.9 RS-232 Setup).
You should turn off the Datalogger function before you transmit an extensive printout. This will avoid
contaminating the printout with new Datalogger data. Datalogger reports are sequential ASCII text files.
