PEAK & VALLEY
The Peak and Valley registers will record the lowest (Valley) and the
highest (Peak) readings of the rate input signal. These values are viewed in
the indication display loop and are updated automatically. A User Input can
be programmed to reset the values to the current rate value individually or by
sending the proper command via the serial communication port. The Peak and
Valley values are NOT retained when power to the unit is removed.
NORMAL OPERATING MODE
In the normal operating mode, the up, down, left, and right arrow keys are
used to scroll through the main display loop. In the main display loop, the four
indication displays, scale factor, and program mode module are viewed, as
shown below. In the indication display loop, the up and down arrow keys are
used to scroll to each display. The indication displays are referenced as 1
(RATE), 2 (PEAK), 3 (VALLEY), and 4(COUNT), and are the factory
default settings. The indication displays can be programmed to show other
parameters and automatically scroll if desired (Refer to the Program Displays
Module). When exiting the indication display loop, using the left or right
arrow keys, the last display that was viewed will be the first display to be
viewed when re entering the indication display loop. Also, the last indication
display that was viewed at power down, will be the one viewed on power up.
The Presets and Counter Load values are accessed from any of the
indication displays or from the programming loop. The Count and Rate scale
factors are accessed from the Scale Factors display or when in the
programming loop from the Program Scaling module. In the Program Mode
display, the operator enters the programming loop to access all parameters to
configure the unit. Shown at right is the Main Display Loop.
