6.3.4 Changing the K FACTOR directly
This procedure is helpful for the correction of a ‚mean error‘ that may be determined by monitoring a
certain number of output operations. In the event you observe a mean percentage error during normal
meter operation you may carry out a correction by changing the valid User K Factor by that percentage. In
order to calculate the correction of the USER K FACTOR, proceed as follows:
New calibration factor = old calibration factor x
Example:
Observed mean percentage error E % -0,9 %
Current K Factor 1.000
New USER K FACTOR 1.000 x 100-(-0,9)÷100=
1.000 x (100+0,9)÷100=
1.009
If the meter displays less than the actual amount of liquid output (negative error), the new K Factor must
be greater than the old one (see example). The opposite is true if the value indicated is greater than the
actual amount (positive error).
