From any test screen, the user has access to the Test File
Manager Screen. The user can give the test file/result file
any name up to a maximum of 99 characters. Once saved,
the user can recall the test and execute with the
appropriate settings already set, or recall saved test results
to download into the AVTS database for storage or for
printing.
All output values are metered and displayed
When under automatic computer control (with the AVTS
software), the TVI becomes a meter display for all of the
MPRT outputs. The metered values are displayed to
Meter Display Screen
TVI Default Setting Screen
Transducer Test Screen
In the above example, a three-phase, 3 Element Watt
Transducer is being tested. The actual output watts is
calculated based upon the measured values from the
MPRT into the transducer, and the transducer watts
is calculated based upon the measured output
voltage/current from the transducer. A % error is
automatically calculated and displayed. A vector
representation of the voltage and current outputs
is also displayed.
Use the File Manager to organize all test results
The TVI has sufficient internal memory to save hundreds
of test and result files. To manage the tests and results, the
MPRT has a File Manager screen.
File Manager Screen
provide continuous real-time verification of the MPRT
outputs, even when under automatic control.
Output values are displayed with a vector display, which
shows the vector relationship between the output voltage
and currents.
User customized configuration
The user may customize how the unit displays phase
angles (0-360° Lead/Lag or ± 180°), and set default values
of voltages, currents and frequency. The user may also
select a language for prompting the operator. Five
language choices are currently available, English, French,
German, Portuguese and Spanish.
Other default settings include GPIB and IP addresses,
Serial Port settings, Battery Simulator output and screen
background colors.
