The following is a list of abbreviations as they appear on the display and front panel of the unit.

ABBREVIATION

DESCRIPTION

FACTOR

SCALING FACTOR - For A and B Inputs.  Each input has a separate 5 digit dividing scale factor.

DP F A

DECIMAL POINT FOR FACTOR A - Enter location of decimal point for scaling Factor A by pressing the
button under the digit where the decimal is desired.

DP F B

DECIMAL POINT FOR FACTOR B - Enter location of decimal point for scaling Factor B by pressing the
button under the digit where the decimal is desired.

COUNT

PORTION OF MENU FOR SETTING COUNTER VARIABLES

RST 0

RESET TO 0 - Counter will reset to 0.  Input A will  count up from 0.  Input B will subtract (count down) in A
Sub B mode.  Input B will add (count up) in A Add B mode.

SET PR

SET TO PRESET - Counter will reset to preset A.  Input A will count down from preset A.  Input B will count
up (add) in "A add B" mode and input B will count down (subtract) in "A sub B" mode.

DP LOC

DECIMAL POINT LOCATION  - Enter desired location of decimal by pushing the button under the digit  where
the decimal is desired.  Changing the decimal will change the decimal location in the A & B counters as well
as the rate display.

A NET B

NET RESULT OF ADDING OR SUBTRACTING A & B INPUTS

A SEP B

A & B INPUTS ARE SEPARATE - A & B are not added or subtracted.

A SUB B

A SUBTRACT B - The number of scaled pulses from Input B are subtracted from the number of scaled pulses
from Input A.  (-99999 TO 999999)

A ADD B

A ADD B - The number of scaled pulses from the A Input are added to the number of scaled pulses from the
B Input.

HI CPS

HIGH COUNTS PER SECOND - This sets the unit for high count speeds (0-9.99KHz)

LO CPS

LOW COUNTS PER SECOND – This sets the unit for contact debounce filtering (0-40Hz)

RATE

PORTION OF MENU FOR SETTING RATE VARIABLES

RPS

RATE PER SECOND - The display will read in rate per second.

SCALE

SCALING - Allows unit to display rate per minute or rate per hour.

Z  60

DIVIDE K FACTOR BY 60 - This sets the unit for rate per minute; equal to 60 times rate per second.

Z 3600

DIVIDE K FACTOR BY 3600 - This sets the unit for rate per hour; equal to 3600 times rate per second.

NOR##

NORMALIZING FACTOR - Normalizes (averages) the data being received. Higher settings provide more
normalizing (averaging) for a more stable display. Derived from the equation:

(Old Data x "NOR" + New Data)

("NOR" + 1)

FIGUR ##

SIGNIFICANT FIGURE - This sets the amount (1-5) of meaningful figures the unit will display. (RATE DIS
PLAY ONLY). FOR EXAMPLE: If "2" is set as the figure, a rate of 273.45 will be displayed as 270.

DLY##

DELAY FACTOR - The amount of time (02 to 24 sec.) the unit will "look" for valid data, before the display
defaults to zero. (RATE DISPLAY ONLY)
