• Parameters other than

are measured using an AC signal (AC measurement).
• Rdc measures DC resistance (DC measurement).
• For more information about series equivalent circuit mode and parallel equivalent circuit mode,

To perform DC measurement (DC resistance measurement)
When Rdc is set as a parameter, you can measure the DC resistance Rdc .
For more information about measurement condition settings, see "3.4 Setting Measurement Condi -
tions (basic settings)" (p. 43).
When Rdc is set as a parameter along with other parameters, DC resistance is measured (DC
measurement) after other parameters are measured using an AC signal (AC measurement).
DC measurement is performed automatically using the following series of operations:
Example: When the number of average iterations is 1

1
The DC resistance is measured after setting the generated voltage to 0 V, and the result is
used as the offset value. (See "DC adjustment (reducing measurement error) (DC)" (p. 61).)
2
The DC resistance is measured after outputting 1.0 V.
3
The measurement error is reduced using the offset value, and the Rdc measured value
is output.
• When the sample is a capacitor, it may not be possible to perform DC resistance measurement normally.
• The time required until the DC signal level stabilizes differs depending on the test sample to be measured.
To facilitate more accurate measurement, observe the measurement waveform in advance and set delay
times (adjustment delay and DC delay) to allow the DC signal level to stabilize adequately. (See "Mea -
surement and data acquisition timing" (p. 66).)
