Submenu / parameter
Value range
Remark
Submenu Set the time-out limits and alarm behavior for values over or
under the electrode balance.
The electrode balance is calculated as the ratio between the
electrode AC voltages E1/E2. This value is displayed in [%]. If
the electrode voltage E2 is larger than E1, the value is
assigned a minus sign and the ratio E2/E1 is displayed.

Off Notice: To properly display the electrode voltage, the
electrode zero point must be adjusted. For additional
information, see ‘Submenu Adjustment’ on page 93.
Submenu Set the time-out limits and alarm behavior for values over or
under the magnetic linearity.

Notice: If magnetic linearity is being measured (at least every
5 minutes), the most recently acquired flow rate during the
measurement is retained (approx. 2 s).
