COUNT MODE
Select the count mode that corresponds with your application. The input
actions are shown in the boxes below. For simple counting applications, it is
recommended to use Count with Direction for the count mode. Simply leave the
direction input unconnected.

MODULE MENU (PAR KEY)
Each module has a separate module menu (which is shown at the start of each
module discussion). The PAR key is pressed to advance to a particular parameter
to be changed, without changing the programming of preceding parameters.
After completing a module, the display will return to
  . Programming
may continue by accessing additional modules.
SELECTION / VALUE ENTRY
For each parameter, the display alternates between the present parameter and
the selections/value for that parameter. The SEL  and RST keys are used to
move through the selections/values for that parameter. Pressing the PAR key,
stores and activates the displayed selection/value. This also advances the meter to
the next parameter.
For numeric values, the value is displayed with one digit flashing (initially the
right most digit). Pressing the RST  key increments the digit by one or the user
can hold the RST  key and the digit will automatically scroll. The SEL  key
will select the next digit to the left. Pressing the PAR key will enter the value and
move to the next parameter.
PROGRAMMING MODE EXIT (PAR KEY)
The Programming Mode is exited by pressing the PAR key with  
displayed. This will commit any stored parameter changes to memory and return
the meter to the Display Mode. (If power loss occurs before returning to the
Display Mode, verify recent parameter changes.)
PROGRAMMING TIPS
It is recommended to start with Module 1 for counting or Module 2 for rate.
When programming is complete, it is recommended to record the parameter
programming and lock out parameter programming with the user input or
programming security code.
FACTORY SETTINGS
Factory Settings may be completely restored in Module 3. This is useful when
encountering programming problems.
ALTERNATING SELECTION DISPLAY
In the explanation of the modules, the following dual display with arrows will
appear. This is used to illustrate the display alternating between the parameter
on top and the parameter’s Factory Setting on the bottom. In most cases,
selections and values for the parameter will be listed on the right.

This selects the decimal point position for Counter A and the setpoint value,
if assigned to Counter A. The selection will also affect Counter A scale

COUNTER A SCALE FACTOR
The number of input counts is multiplied by the scale factor to obtain the
desired process value. A scale factor of 1.0000 will result in the display of the
actual number of input counts. (Details on scaling calculations are explained at
the end of this section.)*
