The density factor (dSF
displayed. For kilograms, a density factor of 1.000 is used. For other
units of measure, different density factors are required.
To determine the correct density factor for the unit of measure you would
like to use on the read-out, consider the following:
 The loading post read-out displays the measured quantity in
KG divided by the density factor.
 When the required unit of measure is kg the density factor
should be set to 1. In this case the display will show the
measured quantity in kg
 When another unit of measure is required, the density factor
should be set to the ratio between the required unit of measure
and kgs. In this case the display will show the measured
quantity (kg) / density factor (unit of measure/kg )
For example if you wish to show the display in pounds:
1 pound = 0.4535 Kg so the density factor is entered as 0.4535. If 1 Kg is
now dispensed the display will now read 1 / 0.4535 = 2.205 pounds.
1. Make sure that the loading post is idle.
2. Open the access panel and remove the cover of the C4000
processor box.
3. Press the K-Factor switch once and release.

The display shows
setting for the loading post that you are commissioning.
4. Enter the required Density Factor.
Each press of the K-Factor switch passes you over a digit
in a setting, making the digit blink. Holding the switch down for more than
a second changes whichever digit is currently displayed. If you want to
pass over a setting without changing any digits, keep pressing and
releasing the switch.
F
The meter K-Factor ( ) is a meter correction factor used to ensure the
displayed quantity is correct.
The K-Factor is set during the calibration phase Meter Calibration (see
page 40) and does not require adjusting during service.
1. Make sure that the loading post is not in use.
2. Press and release the K-Factor switch until the required K-factor is
F
shown ( )
3. Enter the required K-Factor.
Each press of the K-Factor switch passes you over a
digit in a setting, making the digit blink. Holding the switch down for
more than a second changes whichever digit is currently displayed. If
you want to pass over a setting without changing any digits, keep
pressing and releasing the switch.
