I2.2 IN FIELD CALIBRATION
FOREWORD
This procedure calls for the fluid to be dispensed into a graduated sample con-
tainer in real operating conditions ( flow rate, viscosity, etc.) requiring maximum
precision.
ATTENTION
For correct K400 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
Not 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.
