• ZPH, menu item 6.7.3
This is a factory-determined hydraulic calibration value at a flow of 0 m/s. This value is
automatically taken from the SmartPLUG of the measuring sensor. For older measuring
sensors without a SmartPLUG, the value must be transferred manually from the nameplate.
• Excitation frequency, menu item 6.7.4
This setting option depends on the type or the nominal width of the sensor or the probes.
Signal Transmitter
TRANSMAG 2
• Immersion check, menu item 6.7.5
The "Tube empty" detection depends basically on the conductivity of the medium. The
switching threshold is set to a typical value.
Adjustment may be necessary in special cases.
Here you have to determine the current internal measured values for electrodes 1 and 2 for a
filled and empty measuring tube under the menu items 'Act.Value El1' and 'Act.Value El2'. The
switching threshold of the immersion check should be set under menu item 'Threshold' to
about midway between these two values.
