Maximum Fill Pressure (Temperature Compensated Units Only)
The maximum fill pressure (PLA and PLb) is the upper limit for
temperature compensated filling. The units of measure are in bar.
PLA is the maximum fill pressure of side A of the dispenser.
PLb is the maximum fill pressure of side B of the dispenser
This is only used in temperature compensated dispensers.
Do not set the maximum fill pressure so that it is below the
target fill pressure.
To adjust the Maximum Fill Pressure

pressure is displayed flow rate is displayed. ( PLA or PLb )

digit in a setting, making the digit blink. Holding the switch down for
more than a second changes whichever digit is currently displayed.
If you want to pass over a setting without changing any digits, keep
pressing and releasing the switch.
4. Let the menu time out so that the value and quantity amounts are

Vehicle Tank Temperature Rise (Temperature Compensated Units Only)
Vehicle Tank Temperature Rise (rA and rb) is used to compensate for
temperature rise in the gas during a fill. As the tank fills, the temperature
of the gas rises. The lighter the tank, the greater the temperature rise will
be.
rA is the vehicle tank temperature rise of side A of the dispenser.
rb is the vehicle tank temperature rise of side B of the dispenser
Typical values for these may be:
 Car filling = 20 [heavy steel cylinder].
 Bus/Truck filling = 30 [lighter carbon wrapped Aluminium cylinder].

tank temperature rise is displayed. ( rA or rb )

more than a second changes whichever digit is currently displayed.
