6.11.7 Power line frequency [powerLineFrequency]
The parameter defines the line frequency of the power supply grid. A selection between 50 Hz
and 60 Hz can be made. By making the correct setting, interferences caused by the power
supply grid can be better suppressed.
6.11.8 Using a power line filter [PowerLineFilterActivated]
Activates the line filter with selection code 1
Selection code
0 Line filter deactivated
1 Line filter activated
6.11.9 External / internal sensor supply [internalExternalAdcSupply]
Activates the external supply of the load cell with selection code 1.
6.11.10 Impedance
Impedance reference (Ohm) [impedanceReference]
The impedance reference can be determined through command 907 after successful
commissioning of the electronic weighing system. After this time, the electronic weighing
system automatically monitors the current impedance with the reference value. When the
maximum permitted deviation is violated, a corresponding bit (impedanceError) is set in the
scale status.
Maximum impedance deviation (% of impedance reference)
[maximumAllowedImpedanceDeviation] 　
This parameter defines the maximum permissible deviation of the currently measured
impedance as compared to the reference impedance. It is specified as percentage in relation
to the impedance reference value.
