8.2.2 IN FIELD CALIBRATION
FOREWORD
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 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 ac-
curate 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 dis-
pensing 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.
8.2.2.1
IN-FIELD CALIBRATION PROCEDURE
OPERATION
Display
1
NONE
K900 in normal mode, not in counting mode.
2
LONG CAL KEY KEYING
K900 enters calibration mode, shows «CAL” and displays the calibration factor
in use instead of total. The words “Fact” and “USER” indicate which of the two
factors (factory or user) is currently in use
3
LONG RESET KEY KEYING
K900 shows “CAL” and the partial at zero. The meter is ready to perform in-field
calibration.
4
DISPENSING INTO SAMPLE CONTAINER
Without pressing any button,
start dispensing into the sample container.
Dispensing can be interrupted and started again
at will. Continue dispensing until the level of
the fluid in the sample container has reached
the graduated area. There is no need to reach
a preset quantity.
