THE DATALOGGER CONTROL MENU

The Datalogger Setup 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
logging interval, and a destination for your Datalogger reports. While the Datalogger Setup menu is
measurement channel specific, this Datalogger Control 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.
Datalogger Control allows you to select a Circular Memory mode that will over-write the oldest Datalogger
data automatically when the Datalogger memory becomes full. Note that due to the data compression
scheme employed, this is only available for dual-channel systems. The [Est Log Time Left] menu 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. For convenience, the
Display Datalogger command is essentially a duplicate of the menu cell in Datalogger Setup. It sends
Datalogger data to the graphic screen with or without line wrapping. For dual-channel systems with
logging enabled on both channels, a screen dump from menu will show data from both channels. The
Output Datalogger command sends data to an external device via the RS-232 serial port. Data trans-
mitted 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.

4.4.1 DISPLAY DATALOGGER

This menu cell allows you to send the Datalogger contents to the display screen. This command is
effective only after a successful install. You can set the report to scroll on the screen with or without
line-wrap. Selecting line wrap, forces a line feed after approximately 40 characters. In addition, you
have to enable datalogging and then select items in the Datalogger Setup menu. Note that this com-
mand transmits the data from both channels.
