4.12.4.
Calibration procedures
1. in-field calibration
2. direct calibration
By pressing the cAl key while the meter is in standby, the display shows the current calibration factor used. two cases can occur:
CASE 1: "FACT"
if no calibration has ever been performed, or the factory setting has been restored after previous calibrations, the following
display page will appear, see fig.20:
Note: The word "Fact" abbreviation for "factory" shows that the factory calibration factor is being used.
CASE 2: "USER"
if on the other hand calibrations have been made by the user, the display page will appear showing the currently used calibration factor
(in this example 0.998), see fig.21.
Note: The word "user" indicates that a calibration factor set by the user is being used.
To confirm the choice of the calibration factor quickly press CAL while "User" or "Fact" are displayed.
4.12.4.1. In-field Calibration Sequence
1. Wait until the METER returns into Standby, (display shows TOTAL), see fig.22.
2. Press cAl key for more than 2 seconds. the meter enters calibration mode and shows
"cAl". the words "fAct" or "user" indicate which factor (factory or user) is currently in
use, see fig.23.
3. Press the meter and hold the reset key. the meter shows "field" and the Batch total
is zero. The meter is ready to perform in-field calibration, see fig.24.
4.12.4.2. process For In-field Calibration
4. Dispense fluid into a sample container without pressing any key, see fig.25.
Continue dispensing until the level of the fluid in the sample container has reached the graduated area, see fig.26.
5. Press RESET key once. The METER detects that the calibration dispensing is finished. An arrow (up/down) appears which indicates
the direction in which the value can be changed via steps 6 & 7.to calibrate the meter, the value indicated by the Batch total
(example 9.800) must be forced to the Container value 9,860 marked on the graduated sample container, see fig.27.
