Calibration
Calibration mode
In field calibration
This procedure calls for the fluid to be dispensed
into a graduated sample container in real
operating conditions ( flow rate, 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.
4.
Don't reduce the flow rate to reach the
graduated area of the container during the
final dispensing stage (the correct method
during the final stages of sample container
filling consists in making short top-ups at
normal operation flow rate).
5.
After dispensing, wait a few minutes to
make sure any air bubbles are eliminated
from the sample container; only read the
Real value at the end of this stage, during
which the level in the container could drop.
6.
Carefully follow the procedure indicated
below.

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.
