OMICRON 163
Using the Quick Test feature
10.9 Impedance measurement
This is a predefined measurement type, intended especially for the quick
measurement of impedances.
To select the Impedance measurement type, use the cursor key to move
the cursor to the Measurement Type field in the CT-Quick card and then press
the Imped. soft key.
Figure 10-19: CT-Quick card and Results card for impedance measurement
For the Impedance measurement type, the CT-Quick card holds the following measurement quantities:
The following values are displayed in the Results Impedance card:
Table 10-13: Parameters for Impedance measurement type
Parameter Description
Output The output signal type is fixed to "AC".
V/I Operating mode of the internal signal generator: voltage or current source. Fixed to
"Current".
Amplitude RMS value of the output current. Adjustable by the user.
Possible values: 0 to 5A.
Default: 1.00A.
f Frequency of the output signal. Adjustable by the user.
Possible values: 5.0 to 400.0Hz or soft keys 16.7Hz, 50Hz, 60Hz or 400Hz.
Default: 50Hz
Table 10-14: Values displayed for Impedance measurement type
Value Description
OUTPUT Internally measured RMS value and phase of the output current.
SEC RMS value of the voltage measured at input SEC.
This input is considered as the phase reference, therefore the phase is always 0.
PRIM Not used for impedance measurement.
Z Measured impedance, calculated from the magnitude and phase angle of the output
signal and the voltage measured at input SEC.
cos
Ď•
Power factor of the measured impedance.
