The operating modes of the C48 Counter are programmed using the front
panel keypad. Accessibility to the Programming Menu depends on the Program
Disable Function setting (See Front Panel Accessible Functions With Program
Disable, page 14, for available settings).
Note: Before attempting to program the C48C, read the section Programming
General Description, page 15, for detailed information on using the front
panel keypad to navigate through the Programming Menu.

Access Prescaler Value
This parameter configures the type of access given to the
Prescaler Value when in normal operating mode with
Programming disabled. For more information on Program
Disable, see page 14.
Prescaler (0.00001 - 9.99999*)
The Prescaler is used to convert a pulse input signal to the
desired units of indication. For each pulse input, the
Prescaler value is added to or subtracted from the internal
count value. A prescaler of 1.00000, provides unity scaling,
i.e., for every pulse input, the display changes by 1. The
prescaler value selected will affect the maximum count rate
(See Appendix B - Specifications, page 39).
It is important to note that the precision of a counter
application cannot be improved by using a prescaler greater
than 1.
*Limited to 1.00000 or less on Prescaler Output Model or
when Counter 2 is assigned to total on the Batch Counter.
