6. Press reset key once. the arrow changes direction. the operation can be repeated to alternate the direction of the arrow,
see fig.28.
7. Press "cAl" key to change the value in the direction indicated in the arrow. the reading changes:
- by one unit for every short press of the cAl key.
- continually if the CAL key is kept pressed, see fig.29.
8. Press and hold RESET key for more than 2 seconds. The METER is informed that the calibration procedure is finished. The meter
calculates the new USER K FACTOR for a few seconds, see fig.30.
9. The new USER K FACTOR is shown for a few seconds, after which the restart cycle is repeated to finally achieve standby condition,
see fig.31.
10. The METER stores the new calibration factor and is ready to begin dispensing, see fig.32.
4.12.4.3. Direct Calibration Sequence
if normal meter operation shows a mean percentage error e, (obtainable on the basis of several performed dispensing operations),
this can be corrected by applying a correction to the current calibration factor as shown below :
new cal. factor = old cal factor x
example:
error percentage found e%
current calibration factor
new user K fActor
1. Wait until the METER enters Standby (display shows TOTAL), see fig.33.
2. Press and hold cAl key. the meter enters calibration mode and shows "cAl". the words "fact" or "user" indicate which factor
(factory or user) is currently in use, see fig.34.
3. Press and hold RESET key. The METER shows "CAL", "Field" and the Batch Total at zero. The meter is ready to perform in-field
calibration, see fig.35.
4. Press and hold reset key. "direct" appears together with the current calibration factor. An arrow appears (upwards or downwards)
defining the direction (increases or decreases) of the reading, see fig.36.

= 1.000
= 1.000 * [(100 – ( - 0.3))/100]
= 1.000 * [(100 + 0.3)/100]
= 1.003
