NO OPERATION
At the end of the calculation, the new USER K FACTOR is
shown for a few seconds, after which the restart cycle is
repeated to finally achieve standby condition.
IMPORTANT: From now on, the indicated factor will
become the calibration factor used by the Meter and will
continue to remain such even after a battery change.

NO OPERATION
The meter stores the new work calibration factor and is ready
to begin dispensing, using the USER K FACTOR that has just
been calculated.
Direct modification of k factor
If normal Meter operation shows a mean
percentage error, this can be corrected by
applying to the currently used calibration factor
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).

LONG CAL KEY KEYING
Meter 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 used.

Calibración
Calibration mode
New cal. factor = Old cal factor x
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.
