SCALE FACTORS
28
The Model 5886-1400 Control includes the ability
to scale incoming counts. This means that for each
pulse received on the count inputs, a fraction or
multiple of that pulse is counted. Scaling can be
used to compensate for wear on measuring
wheels, consistent material slippage or material
stretch, to make conversions between different
units of measure (inches to centimeters, for exam-
ple) or to totalize parts produced from multiple part
manufacturing processes (such as 6 parts pro-
duced for each operation of a press).
Figure 22.
Table of Scale Factors versus Count Speed
The scale factor can be a number from 0.0001 to
9.9999. This number becomes a factor by which
incoming count pulses are multiplied. The sum of
the scaled count pulses is shown on the front
panel display.
ENTERING A SCALE FACTOR
Function 5 selects the Scale Factor. Note that any
jumper connected to the Program Inhibit terminal
on the rear panel of the counter must first be dis-
connected before the Scale Factor may be modi-
fied. To change the Scale Factor, follow these
steps:
1. Press the “FUNCTION” key. The display
blanks to indicate that the key has been
pressed.
2. Press the “5” key. The display indicates this
digit.
3. Press the “ENTER” key. The current value for
the Scale Factor is displayed. If the value does
not need to be changed, proceed on to step 6
below.
4. Press the digit keys for the desired entry. Note
that for a Scale Factor of 1 the entry of 10000
