Setting Measurement Conditions (basic settings)
Measurement range (AC/DC)
There are the following three methods for setting the measurement range.
AUTO (p. 46)
The most suitable test range is set automatically.
(This setting is useful when measuring a sample whose impedance varies great-
ly with measurement frequency or when measuring an unknown sample.)
HOLD (p. 47)
The measurement range is xed. The range is set manually.
(High-speed measurement is possible.)
JUDGE SYNC
(JUDGE synchroni-
zation)(p. 48)
The optimal range is set automatically based on the comparator or BIN mea-
surement judgment standard.
(This setting is useful when measuring a sample whose impedance varies great-
ly with measurement frequency.)
• Ranges consist of impedance values. Consequently, values for measurement parameters other than im-
pedance are calculated based on the measured |Z| and
θ
values.
See "Appx. 1 Measurement Parameters and Calculation Formula" (p. Appx.1).
• Enabling the HOLD setting or AUTO setting while the JUDGE SYNC setting is on will cause the JUDGE
SYNC setting to be turned off.
• The selection of ranges that can be set during AC measurement varies with the measurement frequency,
DC bias on/off setting, and cable length setting. For more information, see p. 211 of "10.6 Measurement
Range and Accuracy".
• The guaranteed accuracy range varies depending on the measurement conditions. Check the accuracy
assured ranges in "Guaranteed accuracy measurement level range" (p. 213).
• The range of impedance for each range for which accuracy is guaranteed refers to the total impedance for
the sample and measurement cables (probe and xture) (p. 190).
• When the measurement value is outside the guaranteed accuracy range, the following
• icon appears at the top of the screen.
This issue may be the result of the following causes. Check the guaranteed accuracy range as described
in "Guaranteed accuracy measurement level range" (p. 213) and either change the measurement signal
level and measurement range or use the measured value for reference purposes only.
• The test signal level is too low: Increase the test signal level.
• The current measurement range is not appropriate: Either change the measurement range or change to
the AUTO setting so that the instrument can select an optimal range automatically.
