In field calibration
This procedure calls for the fluid to be
dispensed into a graduated sample container
in real operating conditions
viscosity, etc.) requiring maximum precision.
attention
For correct meter calibration, it is
most important to:
1. When the Factory Factor is confirmed,
the old User factor is deleted from the
memory.
2. Use a precise Sample Container with a
capacity of not less than 5 litres, featuring
an accurate graduated indicator.
3. ensure calibration dispensing is done at a
constant flow rate equivalent to that of
normal use, until the container is full.

LONG CAL key keying
The meter enters calibration mode, shows <<CAL>> and
displays the calibration factor in use instead of partial. The
words "Fact" and "USER" indicate which of the two factors
(factory or user) is currently in use.
Important: This factor is that which the instrument
also uses for field calibration measurement
operations.

LONG RESET key keying
The meter shows "CAL" and the partial at zero. The Meter
is ready to perform in-field calibration.
