NORMA 4000/5000
Operators Manual
7-16
You can either:
• Enter the transducer ratio (U over I) at the external current meters and instruct the
device to calculate the final scale factor.
• Or enter the scale factor at the current transducer so that the final scale factor can
be calculated.
The parameters of the formula must be entered as follows:
• Scale factor x transducer ratio, whereby:
o Scale factor is generally "1.0000" (one).
o Transducer ratio is current (in amperes) to voltage (in volts).
Note
If you select Set All to apply the configuration to all channels, only the
scale factor is transferred. If shunt values U/I are entered, the scale factor
is always 1, and Set All is not available. If probes are used, it is generally
easier to enter the transducer ratio, and Set All is thus not recommended.

1. Move the cursor to the value in column Scale and press Enter.
A dialog window showing the scale formula is displayed.
2. Select a value for each parameter and confirm by pressing Enter.
The settings are shown in column Scale.
3. Save the configuration settings by pressing the SAVE function key.
Configure Coupling
By configuring the coupling, you determine the current you wish to analyze. Select AC to
analyze alternating currents; select DC to analyze direct and alternating current.
1. Move the cursor to the field in column Coup and press Enter.
The options AC and DC are displayed.
2. Select AC or DC and confirm with Enter.
The settings are shown in column Coup.
3. If you wish to configure all three current channels in this way, press Set All.
4. Save the configuration settings by pressing the SAVE function key.
