Deleting an Instrument Icon 3-12.
To delete an instrument icon, select Setup | Delete Instrument Icon. A message
appears warning you that the instrument’s configuration will be lost. If you
choose to delete the icon, it will disappear from the Icon Bar in the Main Window.
Designating Instruments as Group or Asynchronous 3-13.
You can designate instruments as grouped or asynchronous (standalone). NetDAQ
Logger treats grouped instruments as one large instrument, logging all their scan
data to one data file. A group consists of one Master instrument, and one or more
Slaves. Scanning for the entire group is controlled by the configuration of the
Master instrument.
For the ASCII and binary file formats, NetDAQ Logger records each Master scan
along with the set of scans from the Slave instruments that match closest in time
to the Master scan. NetDAQ Logger uses the timestamp for the Master as the
timestamp for the whole scan record. NetDAQ Logger can best associate the
Slave data with the correct timestamp when scanning for all the grouped
instruments is properly synchronized. No merging of data is performed when
recording in the TL format but proper synchronization is still important for
accurate correlation of data between instruments. Use the following guidelines to
minimize non-synchronization errors.
• Wired Group
To reliably synchronize a group instrument, connect the TO (Trigger Out) line
of the Master to the TI (Trigger In) of each Slave (along with a common
connection to the ground terminals). Check the “Group is Externally Wired”
check box in the Group Instruments dialog box. See “External Wiring for a
Group Instruments” in Chapter 2 of this manual.
