8.2.3 DIRECT MODIFICATION OF K FACTOR
This procedure is especially useful to correct a “mean error” obtainable on the basis of several performed dispens-
ing operations. If normal K900 operation shows a mean percentage error, this can be corrected by applying to the
currently used calibration factor a correction of the same percentage. In this case, the percentage correction of the
USER K FACTOR must be calculated by the operator in the following way:
New cal. factor = Old cal. factor
*
(
100 - E%
100
)
Example Error percentage found E% - 0.9 %
CURRENT calibration factor 1,000
New USER K FACTOR 1,000 * [(100 – ( - 0,9))/100]=
1,000 * [(100 + 0,9)/100] =
1.009
If the meter indicates less than the real dispensed value (negative error) the new calibration factor must be higher
than the old one as shown in the example. The opposite applies if the meter shows more than the real dispensed
value (positive error).

1
NONE
K900 in normal mode, not in counting mode
2 LONG CAL KEY KEYING
K900 enters calibration mode, shows “CAL” and displays the calibration factor
being used instead of the partial. The words “Fact” and “User” indicate which of
the two factors (factory or user) is currently being us
3 LONG RESET KEY KEYING
K900 shows “CAL” and the partial at zero.
K900 is ready to perform in-field calibration by dispensing
4 LONG RESET KEY KEYING
We now go on to Direct change of the calibration factor: the word “Direct” ap-
pears together with the Currently Used calibration factor. In the bottom left part
of the display, an arrow appears (upwards or downwards) defining the direction
(increase or decrease) of change of the displayed value when subsequent opera-
tions 5 or 6 are performed
5 SHORT RESET KEY KEYING
Changes the direction of the arrow. The operation can be repeated to alternate
the direction of the arrow.
6 BSHORT/LONG CAL KEY KEYING
The indicated value changes in the direction indicated by the arrow
- one unit for every short CAL key keying
- continually if the CAL key is kept pressed. The speed increase rises by
keeping the key pressed.
If the desired value is exceeded, repeat the operations from point (5).
