TTR330
The TTR330 offers a new user interface which allows
the operator to interact with the PowerDB ONBOARD
software system via full QWERTY and navigation keypads
as displayed on an 8.4” VGA bright-color screen. One of
the primary benefits of this interface is that it displays the
actual test form on the screen. An advanced feature of the
TTR330 allows the user to customize these test forms via
optional full-version PowerDB.
Other primary features of the TTR330 include three
communications ports (two USB, one Ethernet). The USB
“host” ports can be used for connecting directly to an
optional printer (to print full size 8.5” x 11” completed test
forms) and for data storage to a USB memory device (for
later printing, analysis, archiving, and/or trending). The
Ethernet port allows the TTR330 to interface (on a bi-
directional basis) directly to a PC.
