Description
Cur. Range
Current range options:
-
Shunt:
Auto, 0.1A,
1A, 10A (
when "Ext. Sensor" is not selected
)
-
Ext. Sensor:
Auto, 0.1V, 1V, 10V (when "Ext. Sensor" is selected)
Ext. Sensor
Choose whether to use an external sensor.
When the external sensor is selected/deselected, you must reset the current
range.
If an external sensor is not selected, the current signal is directly connected to
the current channel of 10A, and the current is measured via the internal shunt;
If an external sensor is selected, the current is measured by connecting the
current signal of external sensor output to the BNC interface.
Cur. Ratio
(A/A)
Scale of an external current sensor (CT). After setting the scale of the external
current sensor correctly, the Analyzer automatically calculates the actual
current value of the measured signal based on the current scale and the
measured value.
The ratio settings are, A/A and mV/A.
If the internal shunt is selected, the current scale represents the ratio of the
actual current (A) to the input current (A) on the shunt (that is A/A).
If an external sensor (BNC) is selected, the current ratio represents input
voltage (V) on the BNC port to the ratio of the actual current (A) of the
connected sensor (expressed as mV/A).
For example, when connecting a current sensor probe with an output sensitivity
of 1 mV/A, which represents a 1:1000 ratio, the Cur. Ratio (A/A) on the
Analyzer should be set to 0.001.
Cur. Line Filter
Current signal filter options:
-
Off
: No current filter is used.
-
650 Hz:
Automatically turn on the line filter, and the cutoff frequency is
650 Hz. Use
to observe the synthesis frequency signal of the frequency
conversion system.
-
10 kHz:
Automatically turn on the line filter, and the cutoff frequency is
10 kHz. Use
for anti-aliasing.
Inserting a current measurement circuit has a direct impact on current
and power measurements. When the line filter is turned on, the
measurements do not contain high frequency components. Noise from
the frequency inverter or distorted waveform can be removed.
