The  selection allows the SEL key to toggle through the enabled
displays.
FRONT PANEL DISPLAY SELECT ENABLE (SEL)
The  selection allows the RST key to reset the selected counter(s). The
shaded selections are only active when Counter B is enabled (Dual Count Mode
or batch counter).
FRONT PANEL COUNTER RESET ENABLE (RST)
The  selection allows the display to automatically scroll through the
enabled displays. The scroll rate is about every 4 seconds.
DISPLAY SCROLL ENABLE
Enter the desired Display Intensity Level (1-5). The display will actively dim
or brighten as levels are changed.

The Security Code determines the programming mode and the accessibility
of programming parameters. This code can be used along with the Program
Mode Lock-out () in the User Input Function parameter (Module 1).
Two programming modes are available. Full Programming mode allows all
unit parameters to be viewed and modified. Quick Programming mode permits
only user selected values to be modified, but allows direct access to these values
without having to enter Full Programming mode.
Entering a Security Code from 1-99 enables Quick Programming mode, and
displays a sublist to select which values appear in the Quick Programming
menu. All of the values set to
 in the sublist are accessible in Quick
Programming. The values include Setpoints (, ), Output Time-outs
(, ), Count Load value () and Display Intensity ().
Programming any Security Code other than 0, requires this code to be entered
at the  prompt in order to access Full Programming mode. Quick
Programming mode, if enabled, is accessed before the  prompt appears.

INPUT FREQUENCY CALCULATION
The meter determines the input frequency by summing the number of falling
edges received during a sample period of time. The sample period begins on the
first falling edge. At this falling edge, the meter starts accumulating time
towards Low Update and High Update values. Also, the meter starts
accumulating the number of falling edges. When the time reaches the Low
Update Time value, the meter looks for one more falling edge to end the sample
period. If a falling edge occurs (before the High Update Time value is reached),
the Rate display will update to the new value and the next sample period will
start on the same edge. If the High Update Time value is reached (without
receiving a falling edge after reaching Low Update Time), then the sample
period will end but the Rate display will be forced to zero. The High Update
Time value must be greater than the Low Update Time value. Both values must
be greater than 0.0. The input frequency calculated during the sample period, is
then shown as a Rate value determined by the scaling calculation.
