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 (PROCESS), 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 the
right is the Main Display Loop.
