Timer
Due to the timer complexities on the MPRT there are two timer screens. There is a basic timer
control screen and the complex timer control screen. When the user presses the Timer Setup
button anywhere in the TVI the user will be first presented with the basic timer setup screen. This
screen will provide the user with the capability to setup the timer for nearly all relay testing
requirements. If the basic timer setup screen does not provide all the capability required the user
can press the Complex Timer Setup button. This screen will provide the user the capability of
adjusting all the timer input and output setting parameters.
