3.3 Calibration
In the factory the meter is calibrated for the medium water transported at a mean flow rate of 40 l/min. Various
operating conditions such as slower flow rates or the transportation of media with greater viscosity can result in
measurement inaccuracy (see chapter B 1.6).
To adjust to these operating conditions, a changeable correction factor can be used to recalibrate the flow meter
in manual mode. The correction factor is either entered directly or the electronic evaluating unit calculates the
right correction factor according to a comparative measurement between the displayed and the actual filled
volume.
The flow meter is also equipped with nine addressable memory locations (memory numbers 1-9), in which
already ascertained correction factors can be stored and copied to the main memory (memory number 0) if
required.
3.2.11 Locking function automatic mode
The locking function in automatic mode makes it impossible to change over to manual mode and prevents
inadvertent input of a new filling volume. This helps to prevent operator errors when filling always the same
volumes.
The following functions remain active even when the keypad is locked: RESET, START, STOP, totalizer (TOT),
display flow rate (SPEED) and cycle counter (see chapter C 3.2.8).
