7.1.9. Zero setting

The zero-setting function is useful in the cases where the actual flow rate is very small (e.g. due to leakage
in closed valves) and for all practical purposes equal to zero. This function can only be used with meters in a
single flow-direction application. Should you open the zero-setting programming mode by mistake (not
wishing to change the zero setting), proceed using the Cancel-Zero setting sequence of commands.
Menu: Zero setting, depress
The display will read "Setting Completed" and show the flow rate as indicated by the meter prior to entry to
the programming mode. Make a note of this value as it cannot be otherwise reconstructed once the new zero
setting has been completed. Depress . The basic programming menu will reappear on the display with the
"Zero Setting" item selected.
The new zero setting will become effective upon leaving the meter programming mode. At the same time,
three flashing exclamation marks will appear on the display showing the actual flow rate values.

actual maximum flow rate is lower than Qmax.
Menu: 100 percent, depress
The display will read "100 percent xxxx". Using push-button move the cursor to the desired decimal
