6.1.4. CALIBRATION OF THE PETROL DISPENSERS WITH ULTRA HIGH FLOW (/UH)
Very high‐performance fuel dispensers (above 120 L/min; marked /UH) include two pumps and two
meters ‐ the main pump & meter and the auxiliary pump & meter. Calibration of the meters is performed
in the same way as in chapter 6.1.3, only the following procedure must be used:
a) disconnect the auxiliary pump
b) calibrate the main meter as described in 6.1.3
c) connect the auxiliary pump
d) calibrate the auxiliary meter settings as described in 6.1.3
NOTE
The auxiliary pump can be disconnected and connected either directly in the dispenser's electronic
cabinet by disconnecting the auxiliary pump motor contactor or by setting a parameter, eg PDEX: P84 = 0
(OFF) / 2 (ON). PDEX5: M8 / P11 = 0 (OFF) / 1.2... (ON).
NOTE
In the case of automatic electronic calibration of the meter (PDEX5 counter), it is not necessary to
mechanically disconnect the pumps. When setting parameter M6‐P15 = 1 and M6‐P15 = 2, only one pump
(main / auxiliary) is always switched on.
